Cell Energy Test 2020

Photosynthesis is to chloroplasts as cellular respiration is to

• chloroplasts

• cytoplasm

• mitochondria

• nuclei

Students are studying the rate of photosynthesis in bean plants. Which of the following environmental condition changes would MOST directly affect the photosynthetic activity of the plant cell?

• oxygen concentration in the air

• sugar concentration in the water

• carbon dioxide concentration in the air

Single-celled algae and multicellular plants both perform photosynthesis. Photosynthesis is the process by which both types of organisms

• make food

• get rid of wastes

• extract energy from food

• reproduce

What is the original source of almost all the energy in most ecosystems?

• carbohydrates

• sunlight

• water

• carbon

A student is collecting the gas given off from a plant in bright sunlight. The gas being collected is probably

• ATP

• Carbon Dioxide

• Vaporized Water

• Oxygen

If carbon dioxide is completely removed from a plant's environment, what would you expect to happen to the plant's production of high-energy sugars?

• More sugars will be produced

• No sugars will be produced

• The same number of sugars will be produced without carbon dioxide

• Carbon dioxide does not affect the production of high-energy sugars in plants.

During the process of photosynthesis, plants take in _________ from the environment and release__________ back into the environment.

• oxygen, nitrogen

• oxygen, carbon dioxide

• carbon dioxide, nitrogen

• carbon dioxide, oxygen

The _________ of plants captures energy from sunlight and converts it into chemical energy.

• Mitochondria

• Vacuoles

• Chloroplast

• Cell Wall

____________ is the process plants use to capture the sun's energy and build carbohydrates that store energy.

• Cellular Respiration

• Fermentation

• The citric acid cycle

• Photosynthesis

Under which conditions would a cell use fermentation to make energy?
