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 products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that is consumed during a chemical reaction to form products.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide, water, and sunlight.

Front

Where does cellular respiration occur in the cell?

Back

Cellular respiration primarily occurs in the mitochondria of the cell.

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 vacuoles in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen.

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.
