what are the two main functions of the stem?

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.

The xylem and phloem carry water and nutrients up and down the length of the stem and are arranged in distinct strands called vascular bundles. The epidermis is a single layer of cells that makes up the dermal tissue covering the stem and protecting the underlying tissue.

What is the function of xylem and phloem? The woody tissue of a stem that carries water and dissolves minerals upward from the roots to the leaves. The vascular tissue in plants that transports food manufactured in the leaves to the rest of the plant.

1: Xylem and phloem: Xylem and phloem tissue make up the transport cells of stems. ... These cells are joined end-to-end to form long tubes. Vessels and tracheids are dead at maturity. Tracheids have thick secondary cell walls and are tapered at the ends.

The most vital function is the process of converting carbon dioxide into oxygen. Secondarily the leaves and branches collect dust and dirt from the air and then provide pathways back to the ground when it rains.

The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It also plays a role in conduction. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem.

Stems possess nodes and internodes, but roots do not have. Stem branches are superficial or exogenous and develop from axillary buds; on the other hand, root branches are deep-seated or endogenous, though root branches do not arise from any specific area.

The Eustachian tube has three primary functions: 1) ventilation of the middle ear so that ambient pressure and middle ear pressure are similar; 2) protection of the middle ear from reflux of nasopharyngeal secretions and bacterial flora; and 3) drainage of secretions from the middle ear into the nasopharynx.

The ear's function is to transmit and transduce sound to the brain through the parts of the ear: the outer ear, the middle ear and the inner ear. The major task of the ear is to detect, transmit and transduce sound. Another very important function of the ear is to maintain our sense of balance.

The first root that comes from a plant is called the radicle. A root's four major functions are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) trans locating water and minerals to the stem.

There are two types of stem cuttings: tip cuttings, which include the apex or plant tip and a small portion of the stem; and section cuttings, which include a 2- to 3-inch section of stem (not including the apex or plant tip> and leaf joint.

The human skeleton serves six major functions: support, movement, protection, production of blood cells, storage of ions, and endocrine regulation.

Brainstem. The brainstem (brain stem) is the distal part of the brain that is made up of the midbrain, pons, and medulla oblongata. Each of the three components has its own unique structure and function. Together, they help to regulate breathing, heart rate, blood pressure, and several other important functions.

The two main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy.
