Stems, in botany, axillary, with shoots and shoots with leaves, and at its basal end roots. The plant carries water, minerals and food to other parts of the plant. It can also store food and green plants make food. In most plants the stem is the main vertical shoot, some it is indistinct and some it is modified and similar to other plant parts (for example the underground stem may look like a root).

The main function of the stem is to support the leaves; To direct water and minerals to the leaves, they can be converted into usable products by photosynthesis. And transport these products from the leaves to other parts of the plant, including the roots. The stem carries water and minerals from the roots to the leaves through some vascular tissue in the xylem. The movement of synthetic food from the leaves to other plant organs occurs primarily through other vascular tissue in the stem called the phloem. Food and water are also often stored in the stem. Examples of food storage plants include specialized forms such as tubers, tubers, stems and stalks, and trees and shrubs. Water storage is established at high levels of cacti stems and all green stems are capable of photosynthesis.

The young roots or first shoots of the embryonic plant emerge from the seed after the roots have first emerged. The growing part at the top of the shoot is the shoot at the end of the plant, and by the continuation of this shoot and the adjacent tissue, the stem grows taller. Shoots and leaves grow from the stem at intervals called nodes; The intervals on the stem between the nodes are called internodes. The number of leaves appearing at the nodes depends on the type of plant; One leaf per node is common, but two or more leaves can grow at the nodes of some species. When a leaf falls off a stem at the end of the growing season, it leaves a scar on the stem due to the rupture of the vascular bundle (process) that connects the stem and the leaves. As the stem continues to grow, later shoots are produced that develop into later shoots, more or less similar to the parent stem, and these eventually determine the division of the plant. In later trees, the shoots develop into branches, where later shoots, called twigs or branches, occur. The point where the leaves turn axially from a stem is called the axil. The shoot that forms at the axis of the previously formed leaf is called the axillary bud, and it looks like the leaf is produced from the tissue of the stem. During the development of such buds, vascular bundles are formed in them, which continue with the stem.

In the stems of young dicotyledons (two-leafed angiosperms) and vascular bundles gymnosperms (xylem and phloem) are arranged in a circle around the central nucleus of the soil tissue called the pith. Surrounding the blood vessels are layers of different thicknesses in different types and are called cortex. Surrounding it and including the outer surface of the stem is a layer called the epidermis. In plants with trees, many secondary tissues are added to these primary tissues. Among the most important are the rings of meristematic cells that give rise to the vascular cambium. This tissue forms between the primary xylem and the phloem and forms the second phloem on the outside and the secondary xylem on the inside. The last tissue is the wood of the tree.

Many plants are perennials and complete their life cycle in one growing season, after which the entire plant, including the stem, dies. In two-year-old plants, the lower part of the stem, which is often modified for food storage, persists after the first growing season, and there are shoots that grow straight up during the second growing season. . In perennial plants, short stems can form new shoots for many years. Plants that make up trees are called trees and shrubs. Stems sprout from the ground or near the ground, while the stems have sprouts.

Usually the stems grow straight or up and down, but they can lie on the ground like Javanese potatoes and strawberries. Stems can climb rocks or plants using roots such as vines. The other vines have twin stems that rotate around the support tree in a spiral, as in Honeysuckle and Hop. In other cases, climbing plants are supported by tendons, which can be specialized stems, as in vines and passion flowers. In tropical climates, twin plants often form dense trees and are called lianas, while in warmer climates they are generally grass vines. A stolon is a tree that bends toward the ground, and when it reaches a moist place, the roots and stems form straight, and eventually a separate plant. Among the underground plants are tubers, tubers. In some plants the stem does not extend during its initial development but instead forms a short conical structure from which the crown of the leaf occurs. These can form a bulb (as in onions and lilies), heads (cabbage, lettuce) or roses (dandelion, plantain. To be successful. In this post you will learn about simple things. Here are four things you can do to help your students succeed in their next STEM challenge.

Is there a successful lesson that every student completes on time? Does success mean that every student has shown some understanding of the content? Maybe success means that every student tries to complete the task?

Success does not mean meeting construction needs. It also does not mean getting all the right answers. You and your students should work together to define your success so that they understand the purpose of your challenges and expectations for their work.

What Is Stem For Kids

Feel that your lesson failed because the students ran into a lot of roadblocks? This happens to everyone! Redefine the situation and consider the learning that students can gain through their challenges.

Maybe they learned how to use new materials. Maybe they thought they should draw their design first. Maybe they know something about who they should not work with in the future. These are valuable lessons for students to learn.

Suppose you really want students to apply their knowledge of angles in their simple machine design, but no group talks about angles or seems to get this information. This does not mean that the lesson failed. Review the content to students after the challenge. You will probably hear a lot of “Oh, right!” And “I forgot about it.”

There are a number of things to consider if you want to prepare students for success, including do’s and don’ts. These four ideas may not apply to each lesson, but they will provide a great start when you plan for your next STEM challenge.

Think about what students will struggle with the most and formulate questions around that part of the challenge. For example, if students are designing a table, help them consider ways to ensure that the table will be limited. Talk about symmetry and balance and encourage them to think about it in their design.

If we show students a potentially completed project, we know they will want to copy it. Remember that helping them to agree with the design process is an important learning process in the STEM classroom.

Consider the factors that will help your lesson run smoothly. Setting up a learning environment and storing some materials in advance will help. For some students, they may need help when it comes to choosing materials that will work well for a planned challenge.

Other students may think outside the box and want to use something else. It’s okay! If students can specify the materials they need and how they think it will help their design, then give them a chance to experiment.
