Front

What are the three essential components for photosynthesis?

Back

Sunlight, carbon dioxide, and water.

Front

What structures in leaves allow gases to enter and exit?

Back

Stomata.

Front

What is the correct equation for photosynthesis?

Back

6CO₂ + 6H₂O + Sunlight → C₆H₁₂O₆ + 6O₂.

Front

What are guard cells?

Back

Cells that open and close stomata to regulate gas exchange and prevent water loss.

Front

Which factor does not affect photosynthesis?

Back

Salt.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for the photosynthesis process.

Front

What is the byproduct of photosynthesis?

Back

Oxygen.

Front

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point.

Front

What is the function of stomata in plants?

Back

To facilitate gas exchange (CO₂ in, O₂ out) and regulate water loss.
