Photosynthesis Respiration

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 respiration?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, carbon dioxide, and water. It occurs in both plants and animals.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, to facilitate the process of photosynthesis.

Front

When does respiration occur in plants?

Back

Respiration occurs in plants both during the day and at night.

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose, which plants use for energy and growth.

Front

What gas do plants take in during photosynthesis?

Back

Plants take in carbon dioxide during photosynthesis.

Front

What gas do plants release during photosynthesis?

Back

Plants release oxygen as a byproduct of photosynthesis.

Front

What is cellular respiration?

Back

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

Front

Why are plants green?

Back

Plants are green because of chlorophyll, the pigment that reflects green light and absorbs other wavelengths for photosynthesis.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in respiration to release energy, while respiration produces carbon dioxide and water, which are used in photosynthesis.
