I WONDER - What Is Photosynthesis?

Photosynthesis is a vital process that allows plants to produce their own food using sunlight, water, and carbon dioxide. Chlorophyll in the chloroplasts absorbs sunlight, converting it into chemical energy. This energy transforms water and carbon dioxide into glucose and oxygen. Photosynthesis occurs in two stages: the light-dependent stage, requiring sunlight, and the Calvin cycle, which can occur without light. This process is crucial for plant growth and, consequently, human survival, as it forms the base of the food chain.

What is the primary role of chlorophyll in photosynthesis?

• To absorb water from the soil

• To release oxygen into the air

• To convert sunlight into chemical energy

• To give plants their green color

How do plants obtain carbon dioxide for photosynthesis?

• Through their roots

• From the soil

• From the water they absorb

• Through stomata in their leaves

What is the main product of photosynthesis that serves as food for the plant?

• Glucose

• Carbon dioxide

• Hydrogen

• Oxygen

Which stage of photosynthesis can occur without sunlight?

• Light-dependent stage

• Calvin cycle

• Chlorophyll stage

• Oxygen release stage

Why is photosynthesis crucial for human survival?

• It helps plants grow taller

• It prevents soil erosion

• It produces glucose for human consumption

• It provides oxygen for us to breathe
