Plant Structure and Functions

Plant Components and Their Functions

• Primary function of roots in plants is to absorb water and nutrients from the soil, anchoring the plant in place, and storing food.

Leaf Structure

• Main function of stomata in plants is to facilitate gas exchange, allowing carbon dioxide to enter and oxygen to leave the plant, thus regulating water loss.

Photosynthesis

• Role of chlorophyll in plants is to absorb light energy, which is then used to power photosynthesis, producing glucose and oxygen.

Plant Vascular System

• Purpose of the xylem tissue in plants is to transport water and minerals from the roots to the rest of the plant, providing structural support.

Leaf Adaptations

• Function of the cuticle in plant leaves is to prevent water loss by forming a waxy, impermeable barrier on the surface of the leaf, protecting it from dryness.
