Photosynthesis & Cellular Respiration

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 is cellular respiration?

Back

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

Front

What is the primary purpose of photosynthesis?

Back

The primary purpose of photosynthesis is to produce glucose for the plant.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

What is produced during the light-dependent reactions of photosynthesis?

Back

The light-dependent reactions produce ATP, NADPH, and oxygen.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH.

Front

What are the products of cellular respiration?

Back

The products of cellular respiration are ATP, carbon dioxide, and water.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, resulting in products like lactic acid or ethanol.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.
