Photosynthesis

Plants have the unique ability to produce their own food through photosynthesis, a process that involves chlorophyll absorbing sunlight to convert water and carbon dioxide into oxygen and carbohydrates. These carbohydrates are stored in various parts of the plant and provide energy for growth and reproduction. Photosynthesis is crucial not only for plants but also for animals, as it provides oxygen and energy through the food chain, sustaining life on Earth.

What is the role of chlorophyll in photosynthesis?

• It stores carbohydrates in the plant.

• It absorbs light energy from the sun.

• It releases oxygen into the air.

• It absorbs water from the soil.

Where do plants store the carbohydrates produced during photosynthesis?

• In the flowers only.

• In the fruits and seeds.

• In the leaves only.

• In the roots only.

What is released into the air as a byproduct of photosynthesis?

• Carbon dioxide

• Oxygen

• Nitrogen

• Hydrogen

How does photosynthesis benefit animals?

• It helps them reproduce directly.

• It supplies them with carbohydrates for energy.

• It gives them a place to live.

• It provides them with oxygen to breathe.

Why is photosynthesis essential for life on Earth?

• It provides shelter for animals.

• It creates water for plants.

• It generates heat for the environment.

• It produces oxygen and food for all organisms.
