Cell Processes and Energy Test Review

Plants use sunlight to make food in a process called

• respiration.
• photosythesis.
• fermentation.

In the second stage of photosynthesis, plant cells

• turn green.
• absorb light.
• make sugars.

Organism that cannot make their own food are called

• autotroph.
• heterotroph.
• amino acids.

Plants are considered

• autotrophs.
• heterotrophs.
• amino acids.

The first stage of respiration takes place in the

• nucleus.
• chloroplasts.
• cytoplasm.

During fermentation, cells

• release energy from sugar.
• make food using sunlight.
• make a copy of their DNA molecule.

What happens during mitosis?

• DNA replication takes place.
• A cell's nucleus divides to form two new nuclei.
• A cell's cytoplasm divides.

In the DNA molecule, adenine pairs only with

• thymine.
• guanine.
• cytosine.

During photosynthesis, plants produce sugars and

• water.
• oxygen.
• carbon dioxide.

Most of the energy that is released during respiration is produced in the

• mitochondria.
• cytoplasm.
• nucleus.
