P4~Photosynthesis

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

What are the main reactants needed for photosynthesis?

Back

The main reactants needed for photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is the main product of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen (O2).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs sunlight, providing the energy needed for photosynthesis.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: CO2 + light + H2O → O2 + glucose.

Front

What is the function of the phloem in plants?

Back

The phloem is responsible for transporting nutrients, particularly sugars produced during photosynthesis, from the leaves to other parts of the plant.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy required to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Front

What is respiration in plants?

Back

Respiration is the process by which plants convert glucose and oxygen into energy, carbon dioxide, and water, which occurs continuously, even in the dark.

Front

What is the stoma in a leaf?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere, which is essential for the respiration of most living organisms.
