Seed kernel diagram diagram base website kernel diagramOn 26.10.2020 by Megar
At one end of the testa, there is a scar, called hilum. The hilum is the position of attachment of seed with its stalk, the funiculus.
Near the hilum a small opening is present, called micropyle, through which water enters the seed. Sometimes a ridge is present beyond the hilum, opposite the micropyle, it is called raphe. It represents the base of the funiculus which becomes fused with integument. The testa are of various natures: It may be tough and leathery in gram Cicer arietinum and pea Pisum sativum of Fabaceae; hard and horny in castor Ricinus communis of Euphorbiaceae; soft and fleshy in gourd Cucurbita maxima of Cucurbitaceae.
The tegmen is much thinner than the testa. It may be closely adpressed in gram, remains free in gourd and sometimes it is absent in pea. The inner part of the seed coat is called kernel. It consists either of the embryo only as in exalbuminous seeds gram or the embryo enclosed within the endosperm as in albuminous seeds paddy, wheat etc. These are the leaves of embryo. Sometimes they store food and become fleshy. But in some cases, they do not store food, remain thin and papery.
The cotyledons are attached to an axis — the tigellum, and the point of attachment is called cotyledonary node. It is the main axis, of which one end is pointed and protrudes out of the cotyledon, it lies next to the micropyle and is called radicle, i. The other end of the tigellum is the plumule, the first apical bud of shoot Fig. In mono- cotyledonous seeds, both radicle and plumule remain covered by protective sheaths, known as coleorhiza and coleoptile, respectively.
Endosperm is the food- reservoir of seed. Top Menu BiologyDiscussion. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes.

The following diagram shows the major components of the Android platform.
The foundation of the Android platform is the Linux kernel. For example, the Android Runtime ART relies on the Linux kernel for underlying functionalities such as threading and low-level memory management. Using a Linux kernel allows Android to take advantage of key security features and allows device manufacturers to develop hardware drivers for a well-known kernel.
The hardware abstraction layer HAL provides standard interfaces that expose device hardware capabilities to the higher-level Java API framework. The HAL consists of multiple library modules, each of which implements an interface for a specific type of hardware component, such as the camera or bluetooth module. When a framework API makes a call to access device hardware, the Android system loads the library module for that hardware component.
For devices running Android version 5. ART is written to run multiple virtual machines on low-memory devices by executing DEX files, a bytecode format designed specially for Android that's optimized for minimal memory footprint.
Prior to Android version 5. If your app runs well on ART, then it should work on Dalvik as well, but the reverse may not be true. Android also includes a set of core runtime libraries that provide most of the functionality of the Java programming language, including some Java 8 language featuresthat the Java API framework uses. The Android platform provides Java framework APIs to expose the functionality of some of these native libraries to apps. These APIs form the building blocks you need to create Android apps by simplifying the reuse of core, modular system components and services, which include the following:.
Developers have full access to the same framework APIs that Android system apps use. Android comes with a set of core apps for email, SMS messaging, calendars, internet browsing, contacts, and more. Apps included with the platform have no special status among the apps the user chooses to install. So a third-party app can become the user's default web browser, SMS messenger, or even the default keyboard some exceptions apply, such as the system's Settings app.
The system apps function both as apps for users and to provide key capabilities that developers can access from their own app. For example, if your app would like to deliver an SMS message, you don't need to build that functionality yourself—you can instead invoke whichever SMS app is already installed to deliver a message to the recipient you specify.

Today, I want to focus on a library to create complex, highly customizable diagrams for your React apps.
React-diagrams offers advanced diagram visualizations for your project. You will be able to display boxes with titles and properties, and links that are connecting those properties. Links can be drawn as curves, or you can specify anchor points to make the connection between the two properties a serie of segments.
Diagrams can be controled by the user. You can move nodes, links, create links between nodes, move and scale the viewport. This library is really customizable, you can customize nearly every part of the rendered diagram, handle events to attach behaviours on clicking on elements or other user interactions.
To install this library, you first need to install it into your React application. Via yarn. Via npm. Then, import it and use it in your React app, in the component that will encapsulate your diagram :.
Once this step is done, you will be able to access all that you need to create a fully functionnal diagram, under the namespace SRD :. You can then render it with the following JSX code :.
There you have a classy diagram! This pattern allows the library to be built around design patterns such as factories, that make the system highly configurable.
In this example we want to draw a diamond shaped node, as shown in this screenshot :. Right after registering default factories from the diagram, we will declare two new factories. This will teach the diagram engine how to draw diamond shaped nodes, and register this new node in the diagram engine.
Event handling allows you to define custom behaviours when interacting with diagrams and execute them when interacting with it. This step is quite easy to reproduce :. This example shows how to bind events to a node model, but you can also bind events to link models and to the main diagram model.
Events for the diagram model. Events for Link models. Events for Node models and Point models. At any time you can use a serialization method to export your dragram in JSON using the serializeDiagram method on your diagram model. You can then restore a previously saved diagram using the deSerializeDiagram method on the same diagram model. Full example available here. Dagre is a library used to reorder diagrams visually. It will reorganize your diagram to make it readable.
This library can work with any diagram libraries and tools, as long as you can retreive positions of your elements and move them programmatically. A full example on how to bind it to storm-react-diagrams is available here. This library is really simple to use if you think about what is going on under the hood.If you are reading this, corn has touched your life in some way.
We eat corn, animals eat corn, cars eat corn well, it can be used as a biofueland we even can eat corn out of a container made from corn think: bioplastics. It is projected that the U. However, what do you know about the corn plant itself? Did you, for example, know that corn is a grass and not a vegetable? Look at a corn cob - you will see the seeds! The kernels that you eat can also be used as the seed source to start new plants. Don't worry; the corn kernels that you eat won't grow in your stomach.
Specific corn plants are set aside to provide seed. The corn plant's growth stages are broken down into vegetative and reproductive stages. Seedlings are dependent on kernel reserves up until about the V3 leaf stage when they become dependent on the roots to take up nutrients.
Corn plants are unusual in that they have two distinct sets of roots: regular roots, called seminal roots; and nodal roots, which are above the seminal roots and develop from the plant nodes. Nodal roots that form above the ground are called brace roots, but they function similarly to the nodal roots below the ground.
Sometimes brace roots actually penetrate the soil and take up water and nutrients. Therefore, corn can be vulnerable to dry soil conditions as they don't have a deep root system.
Corn grows on a single stem called a stalk. Stalks can grow up to ten feet tall. The plant's leaves emerge from the stalk. A single corn stalk can hold between 16 and 22 leaves. The leaves wrap around the stalk, rather than having a stem. The part of the leaf that wraps around the stem is called the node. The tassel and the corn ears are responsible for reproduction and formation of the corn kernels.
The tassel is the "male" part of the plant, which emerges from the top of the plant after all of the leaves have developed. Many male flowers are on the tassel. The male flowers release pollen grains which contain the male reproductive cells. The female flowers develop into the corn's ears, which contain the kernels.
The ears contain the female eggs, which sit on the corn cob. Silks - long strands of silky material - grow from each egg and emerge from the top of the ear. Pollination occurs when pollen is carried from the tassels to the exposed silks on the ear of corn, which is the female flower on the plant.
The male reproductive cell goes down to the female egg contained within the ear and fertilizes it. Each strand of fertilized silk develops into a kernel. The kernels are arranged on the cob in 16 rows. Each ear of corn averages about kernels.The Linux kernel, developed by contributors worldwide, is a free and open-sourcemonolithicmodular i. It is deployed on a wide variety of computing systems, such as embedded devicesmobile devices including its use in the Android operating systempersonal computersserversmainframesand supercomputers.
The Linux kernel was conceived and created in by Linus Torvalds  for his personal computer and with no cross-platform intentions, but has since ported to a wide range of computer architectures. Notwithstanding this, the Linux kernel is highly optimized with the use of architecture specific instructions ISA therefore portability isn't as easy as it is with other kernels e.
Linux was soon adopted as the kernel for the GNU Operating System which was created as an open source and free softwareand based on UNIX as a by-product of the fallout of the Unix wars. The Linux ABI i.
Device drivers included in the mainline Linux must be kept updated by their maintainers in order to stay at pace with the kernel evolution. Furthermore, the interface between the kernel and loadable kernel modules LKMsunlike in many other kernels, is not meant to be stable by design. In AprilLinus Torvaldsat the time a year-old computer science student at the University of HelsinkiFinlandstarted working on some simple ideas for an operating system.
He started with a task switcher in Intel assembly language and a terminal driver.
On 25 AugustTorvalds posted the following to comp. I'm doing a free operating system just a hobby, won't be big and professional like gnu for AT clones. This has been brewing since April, and is starting to get ready.
I've currently ported bash 1. This implies that I'll get something practical within a few months [ On 17 SeptemberTorvalds prepared version 0.
It was not even executable since its code still needed Minix for compilation and play. On 5 OctoberLinus announced the first "official" version of Linux, version 0. It has finally reached the stage where it's even usable though may not be depending on what you wantand I am willing to put out the sources for wider distribution. It is just version 0. After that, many people contributed code to the project, included some developers from the MINIX community. At the time, the GNU Project had created many of the components required for a free operating system, but its own kernel, GNU Hurdwas incomplete and unavailable.
The Berkeley Software Distribution had not yet freed itself from legal encumbrances. Despite the limited functionality of the early versions, Linux rapidly gained developers and users.
Torvalds assigned version 0 to the kernel to indicate that it was mainly for testing and not intended for productive use. When Torvalds released version 0. With the support of the POSIX APIs, through the libC that, whether needed, acts as an entry point to the kernel address space, Linux could run software and applications that had been developed for Unix.
On 19 Januarythe first post to the new newsgroup alt. Linux version 0. It started a versioning system for the kernel with three or four numbers separated by dots where the first represented the major release, the second was the minor releaseand the third was the revision.
The optional fourth digit indicated a set of patches to a revision. The current version numbering is slightly different from the above.Structures of Operating System -NTA NET - Operating System - In Hindi

Occasional updates to stable releases are identified by a three numbering scheme e. After version 1. Starting with version 2. In the stable team was formed as a response to the lack of a kernel tree where people could work on bug fixesand it would keep updating stable versions.The diagram s below can help you find the right part.
