Photosynthesis and Environmental Impact

What is photosynthesis?

• A process where plants convert oxygen and water into carbohydrates using sunlight.

• A process where plants convert carbon dioxide and water into carbohydrates using sunlight.

• A process where animals convert carbon dioxide and sunlight into energy.

• A process where bacteria convert carbohydrates into oxygen and water.

What are the primary requirements for plants to perform photosynthesis?

• Nitrogen and strong roots.

• Abundant water and soil nutrients.

• Sufficient carbon dioxide and abundant sunlight.

• High humidity and warm temperatures.

What are the main products of photosynthesis?

• Carbon dioxide, water, and glucose.

• Oxygen, hydrogen, and carbohydrates.

• Nitrogen, carbon, and protein.

• Sunlight, chlorophyll, and water.

How does oxygen, a product of photosynthesis, benefit the human body?

• It helps in digestion and nutrient absorption.

• It maintains cells, supports brain function, and boosts immunity.

• It strengthens bones and muscles.

• It regulates body temperature and hydration.

How do strong tree roots contribute to environmental protection?

• They absorb excess carbon dioxide from the atmosphere.

• They provide shade and reduce air temperature.

• They hold rainwater to prevent floods and landslides.

• They produce more fruits for animals.
