Question

Give five characteristics each of the following
a. Roots
b. Stems
c. Leaves

Answer 1

Plants are multicellular and eukaryotic, which means that there are a nucleus and membrane-bound organelles in their cells. They produce most of the world’s oxygen and are important in the food chain.

Complete answer:

Roots - The root is usually a part of the plant that is underground. The fixation and absorption of water are primarily responsible for it. The root is known as the root system, with its branches. Its main characteristics are
• The descending portion of the plant axis is the root.
• The root carries unicellular root hairs.
• Without the roots, the transport mechanism will cease to function in many plants.
• It is favorably geotropic.
• The root does not carry leaves or tree buds.

Stems - The stem is the ascending part of the branches, leaves, flowers, and fruits that bear the axis. It emerges from the embryonic plumula of a germinating seed. It bears internodes and nodes. Its main characteristics are
• The descending portion of the plant axis is the root.
• The root carries unicellular root hairs.
• Without the roots, the transport mechanism will cease to function in many plants.
• It is favorably geotropic.
• The root does not carry leaves or tree buds.

Leaves - The leaf is a green, smooth, small, extended lateral appendage of the stem. At a node, this portion is born and bears a bud in its axil. It is exogenous in nature and grows from the shoot apex primordium leaf. It’s main characteristics are
• The node of the stem still holds a leaf.
• Leaf growth is minimal.
• Prominent vascular threads, or veins, are traversed by the leaf lamina.
• The leaves do not contain an apical bud.
• They are carried in acropetal succession on the stem.

Note: A few distinguishing features, structural as well as functional, are shared by terrestrial plants. Maybe their division into shoots and roots is the most basic shared characteristic of most plants. During the evolutionary shift from an aqueous environment to a terrestrial one, the separation between these two parts of the plant came about, and each part is essential in its own way to the ability of the plants to survive on land.
