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 is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the blue and red wavelengths, and 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 is the equation for photosynthesis?

Back

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

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and water availability.

Front

Why do leaves change color in the fall?

Back

Leaves change color in the fall due to decreased chlorophyll concentration, allowing other pigments like carotenoids to become visible.

Front

What is the ultimate source of energy for photosynthesis?

Back

The ultimate source of energy for photosynthesis is sunlight.

Front

What organelle is responsible for photosynthesis?

Back

The organelle responsible for photosynthesis is the chloroplast.

Front

How do plants in the desert adapt to photosynthesis?

Back

Desert plants adapt to photosynthesis by developing features like thick cuticles, deep roots, and CAM (Crassulacean Acid Metabolism) to minimize water loss.

Front

What is the significance of water in photosynthesis?

Back

Water is essential in photosynthesis as it provides electrons and protons for the light-dependent reactions and is a reactant in the overall process.
