Photosynthesis and Plant Functions

The video tutorial introduces the process of photosynthesis, explaining how green plants make their own food using sunlight, carbon dioxide, and water. It covers the roles of chlorophyll and stomata, the functions of plant parts, and the photosynthesis equation. The tutorial also includes an activity to describe the process and a test for starch presence in leaves.

What is the primary role of chlorophyll in plants?

• To protect from pests

• To provide nutrients

• To trap light energy

• To absorb water

Which part of the plant is responsible for absorbing water and minerals?

• Leaves

• Stem

• Roots

• Flowers

What is the function of stomata in the leaves?

• To take in carbon dioxide

• To store water

• To release oxygen

• To absorb sunlight

Which of the following is NOT a requirement for photosynthesis?

• Carbon dioxide

• Sunlight

• Oxygen

• Water

What happens to stomata during the night?

• They open to absorb sunlight

• They close to conserve water

• They open to release oxygen

• They close to absorb carbon dioxide

What are the products of photosynthesis?

• Chlorophyll and starch

• Water and carbon dioxide

• Minerals and sunlight

• Sugar and oxygen

Why can't mushrooms perform photosynthesis?

• They lack chlorophyll

• They don't need sunlight

• They don't have roots

• They grow in soil

Which part of the plant is primarily involved in photosynthesis?

• Flowers

• Roots

• Leaves

• Stem

What is the main purpose of photosynthesis in plants?

• To absorb sunlight

• To create food

• To generate oxygen

• To produce minerals

What is the significance of the iodine test in plants?

• To check for water content

• To test for starch presence

• To measure chlorophyll levels

• To detect carbon dioxide
