Photosynthesis and 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

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What are the main inputs of photosynthesis?

Back

The main inputs of photosynthesis are carbon dioxide, water, and light energy.

Front

What are the main outputs of photosynthesis?

Back

The main outputs of photosynthesis are glucose and oxygen.

Front

What is respiration?

Back

Respiration is the process by which cells break down glucose and oxygen to produce energy, carbon dioxide, and water.

Front

Where does aerobic respiration occur?

Back

Aerobic respiration occurs in the mitochondria of cells.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that occurs in muscle cells when oxygen is scarce, producing lactic acid and energy.

Front

How do animals obtain glucose?

Back

Animals obtain glucose from the food they eat.

Front

True or False: Plants perform both photosynthesis and respiration.

Back

True. Plants perform photosynthesis to produce glucose and oxygen, and respiration to convert glucose into energy.

Front

What is the role of chlorophyll in photosynthesis?

Back

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