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

When do plants perform photosynthesis?

Back

Plants perform photosynthesis only when it is light outside.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

When do plants perform cellular respiration?

Back

Plants perform cellular respiration when it is light or dark outside (all 24 hours).

Front

Do plants produce oxygen?

Back

Yes, plants produce (release) oxygen during photosynthesis.

Front

What happens to blue BTB in the presence of carbon dioxide?

Back

In the presence of CO2, blue BTB will turn yellow.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to store and transfer energy.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for the photosynthesis process to convert carbon dioxide and water into glucose.
