Fotosíntesis: cómo las plantas transforman luz en vida

Photosynthesis is a vital chemical reaction that uses sunlight, water, and carbon dioxide to produce glucose and oxygen. It occurs in the chloroplasts of plant leaves, where chlorophyll captures solar energy. This process is essential for plant growth and sustains the food chain by providing energy and oxygen, making it crucial for life on Earth.

What are the basic ingredients used by leaves to produce food?

• Sunlight, water, and carbon dioxide

• Carbon dioxide, oxygen, and sunlight

• Sunlight, water, and oxygen

• Water, oxygen, and nitrogen

What is the role of chlorophyll in photosynthesis?

• It captures energy from the Sun

• It converts glucose into starch

• It releases oxygen into the atmosphere

• It absorbs water from the soil

Which gas is released as a byproduct of photosynthesis?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

Why is photosynthesis considered essential for the food chain?

• It helps in the decomposition of organic matter

• It forms the base of the food chain by producing food for plants

• It produces oxygen for animals

• It provides energy for the Sun

How does photosynthesis impact the atmosphere?

• By increasing nitrogen levels

• By consuming carbon dioxide and producing oxygen

• By releasing methane

• By reducing water vapor
