Photosynthesis Review

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What role do guard cells play in photosynthesis?

Back

Guard cells regulate the opening and closing of stomata, controlling water loss and gas exchange (CO2 and O2) in the leaf.

Front

What is the significance of sunlight in photosynthesis?

Back

Sunlight provides the energy required for the photosynthesis process, enabling plants to convert carbon dioxide and water into glucose and oxygen.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the role of water in photosynthesis?

Back

Water is a raw material in photosynthesis; it is split into oxygen and hydrogen, with oxygen being released as a byproduct.

Front

How do plants absorb carbon dioxide for photosynthesis?

Back

Plants absorb carbon dioxide from the atmosphere through small openings in their leaves called stomata.

Front

What is the function of the stroma in chloroplasts?

Back

The stroma is the fluid-filled space in chloroplasts where the Calvin cycle occurs, converting carbon dioxide into glucose.
