12/2/24 UNIT 4 REVIEW Q'S (ONLY 2 ATTEMPTS!)

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, and releasing oxygen as a byproduct.

Front

What gases are involved in photosynthesis?

Back

The main gases involved in photosynthesis are carbon dioxide (CO2), which is taken in by plants, and oxygen (O2), which is released as a byproduct.

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

How do plants and animals differ in energy acquisition?

Back

Plants produce their own energy through photosynthesis, while animals obtain energy by consuming plants or other animals.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

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, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis can be affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.

Front

What is the significance of oxygen in cellular respiration?

Back

Oxygen is essential for aerobic cellular respiration as it acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is the main energy currency of the cell?

Back

Adenosine triphosphate (ATP) is the main energy currency of the cell, providing energy for various cellular processes.

Front

What is the process of energy transformation in ecosystems?

Back

Energy transformation in ecosystems involves the conversion of solar energy into chemical energy by producers (plants), which is then transferred to consumers (animals) through food chains.
