Photosynthesis

Front

What is photosynthesis?

Back

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

Front

What are the raw materials needed for photosynthesis?

Back

The raw materials needed for photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

Where does photosynthesis primarily occur in plants?

Back

Photosynthesis primarily occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in chloroplasts that absorbs light energy, which is essential for photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the function of guard cells?

Back

Guard cells regulate the opening and closing of stomata, controlling gas exchange and water loss in plants.

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.

Front

How does light intensity affect the rate of photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis, up to a certain point, after which other factors may limit the process.

Front

What is the role of water in photosynthesis?

Back

Water is a raw material in photosynthesis and is split to provide electrons and protons, and it also helps in the transport of nutrients.
