B.2 Unit 2 Exam - Matter & Energy

Front

What is the primary source of energy for photosynthesis?

Back

The Sun.

Front

Do plants only undergo photosynthesis?

Back

False. Plants undergo both photosynthesis and cellular respiration.

Front

What happens to the phytoplankton population in spring when solar energy increases?

Back

The phytoplankton population typically increases.

Front

What is the significance of photosynthesis in the ecosystem?

Back

Photosynthesis converts light energy into chemical energy, which is essential for life.

Front

How do decomposing phytoplankton affect dissolved oxygen levels?

Back

The rate of cellular respiration increases as bacteria decompose the dead phytoplankton, which can decrease dissolved oxygen levels.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is cellular respiration?

Back

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

Front

Explain the role of chlorophyll in photosynthesis.

Back

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

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy.
