Reference on the roots structure, stem and the leaves

Answer 1

The roots, stem, and leaves are the three main organs of a plant.

Roots: The roots of a plant are typically found underground and serve several important functions. They anchor the plant in the soil, absorb water and nutrients from the soil, and store food for the plant. There are two main types of roots: fibrous roots, which are thin and spread out in all directions, and taproots, which are thick and have one main root that goes straight down into the soil.

Stem: The stem of a plant is the main support structure that connects the roots to the leaves. It also transports water and nutrients from the roots to the rest of the plant and serves as a highway for sugars produced by the leaves during photosynthesis. Stems can be either woody or herbaceous, depending on the plant species.

Leaves: Leaves are the primary sites of photosynthesis, where plants convert sunlight into energy. They are typically broad and flat to maximize their surface area for capturing sunlight. Leaves also play a role in transpiration, the process by which plants release excess water vapor through tiny pores called stomata. Leaves come in a wide variety of shapes, sizes, and colors, depending on the plant species.
