Plant Structure

What is the primary function of the roots in a plant?

• Producing energy through photosynthesis

• Storing excess water and nutrients

• Supporting the leaves and flowers

• Anchoring the plant in the soil and absorbing water and nutrients

Explain the process of photosynthesis in plants.

• Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

• Photosynthesis is the process by which green plants use sunlight to convert oxygen and water into carbon dioxide and glucose.

• Photosynthesis is the process by which plants use water and nitrogen to convert sunlight into carbon dioxide and oxygen.

• Photosynthesis is the process by which plants use moonlight to convert carbon dioxide and water into glucose and nitrogen.

What is the function of the stomata in plant leaves?

• The function of the stomata in plant leaves is to facilitate gas exchange for photosynthesis.

• The function of the stomata in plant leaves is to produce energy for the plant through photosynthesis.

• The function of the stomata in plant leaves is to provide structural support for the leaf.

• The function of the stomata in plant leaves is to store water for the plant.

Describe the structure and function of the xylem in plants.

• Control the opening and closing of stoma

• Primarily for photosynthesis in plants.

• Transports oxygen from the leaves to the roots.

• Responsible for transporting water and nutrients from the roots to the rest of the plant.

What is the role of chloroplasts in plant cells?

• The role of chloroplasts in plant cells is to store water.

• The role of chloroplasts in plant cells is to conduct photosynthesis.

• The role of chloroplasts in plant cells is to produce hormones.

• The role of chloroplasts in plant cells is to regulate temperature.

what is the function of cuticle?
