What is STEM teaching and learning?

STEM is a curriculum based on the idea of educating students in four specific disciplines — science, technology, engineering and mathematics — in an interdisciplinary and applied approach. … This campaign also addresses the inadequate number of teachers skilled to educate in these subjects.

What is an example of a stem vegetable?

Stem vegetables include asparagus and kohlrabi. Among the edible tubers, or underground stems, are potatoes. The leaf and leafstalk vegetables include brussels sprouts, cabbage, celery, lettuce, rhubarb, and spinach. … Seed vegetables are usually legumes, such as peas and beans.

What is the primary function of leaves?

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy.

What are the types of stem?

There are several types of stem cells that can be used for different purposes.Embryonic stem cells. Embryonic stem cells come from human embryos that are three to five days old. … Non-embryonic (adult) stem cells. … Induced pluripotent stem cells (iPSCs) … Cord blood stem cells and amniotic fluid stem cells.

Which part of the plant is most important?

LeavesLeaves. Leaves are the most important part of a plant. They contain chlorophyll that helps the plants to prepare their food using sunlight, carbon dioxide and water. A leaf consists of three main parts- petiole, leaf base and lamina.

What is difference between stem and trunk?

Stems are directly attached to the leaves and don’t have surrounding bark. Meanwhile, the trunk isn’t directly connected to the leaves and has a coat of bark. The trunk also features the tree “rings” which are often the indicators of the tree’s age and growth in its lifetime.

How do I make my plant stems stronger?

Bend your young plant’s stem back and forth to force it to be very thick and strong. Spindly stems can not support heavy flowering growth. An internal oscillating fan will reduce your humidity on the leave’s stomata and improve the stem strength as well.

How are stem useful to us?

Stems do many things. They support the plant. They act like the plant’s plumbing system, conducting water and nutrients from the rootsand food in the form of glucose from the leavesto other plant parts. Stems can be herbaceouslike the bendable stem of a daisy or woody like the trunk of an oak tree.

What is stem in tree?

Trees: The stem is upright, very tall, very thick, hard. It is called the trunk. The trunk of a tree is its stem. • The stem can be underground, for example that of garlic or onion.

What is a flower stem called?

The flower stem is known as a pedicel, and those flowers with such a stem are called pedicellate, while those without are called sessile. In the angiosperms, the flowers are arranged on a flower stem as an inflorescence.

What is a cross section of a stem?

Cross section of a stem: axis of a plant. Epidermis: outer layer of the stem. Phloem vessels: tubes that carry sap. Cambium: new parts of the stem. Cork: protective covering of the stem.

How does a stem work?

The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.

What are 3 main functions of a stem?

A stem connects the roots to the leaves, provides support, stores food, and holds the leaves, flowers, and buds.

What are the three types of stems?

Xylem and Phloem conduct water across the plant. Stems stores food, water, and nutrients. Cells of a stem, meristems, produce new living tissues. Underground stem, Aerial stem, and subaerial stem are three different types of Stem.

What would happen if we break the stem of a plant?

The stem of a tender plant can be easily damaged by high winds, heavy rains or poor handling. This vital part of the plant transports the nutrients from the water and soil to its blossoms and leaves. If the stem becomes broken or bent, it can interrupt this flow and can cause your plant to die.

How are roots and stems similar?

Similarity: Both stems and roots contain vascular tissues (xylem and phloem), the circulatory system of the plant. Difference: In herbaceous stems, the vascular tissues are contained in bundles; these bundles sit relatively near the surface of the stem.

How is stem modified?

Modified stems that grow horizontally underground are either rhizomes, from which vertical shoots grow, or fleshier, food-storing corms. New plants can arise from the nodes of stolons and runners (an aboveground stolon): stems that run parallel to the ground, or just below the surface.

What are the two main types of stems?

There are two main types of stems: woody and herbaceous.

Why are leaves important to humans?

Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe. Living things need plants to live – they eat them and live in them. Plants help to clean water too.
