Day One Review: Biology (Cells)

What will most likely be the result if all of the mitochondria are removed from a plant cell?

• It will be unable to carry out respiration.

• It will lose water through osmosis.

• It will break down the ribosomes in the cell.

• It will be unable to photosynthesize.

What process best explains how a nerve cell and a muscle cell can both develop from the same fertilized egg?

• differentiation

• natural selection

• selective breeding

• genetic engineering

During strenuous exercise, body temperature increases. The body responds to the increase in temperature by sweating, which helps to reduce the body temperature. Which is demonstrated in this situation?

• excretion

• metabolism

• homeostasis

• synthesis

This diagram shows a plant cell. Which structure is found in a plant cell but is absent in an animal cell?

​

​

• 1

• 2

• 3

• 4

Which best explains why muscle cells are different from blood cells?

• A mutation occurs during the development of muscle cells but not in blood cells.

• Different genes are activated in muscle cells than in blood cells.

• Muscles cells experience different environmental influences than blood cells.

• Muscle cells are produced by the brain, but blood cells are produced by the heart.

If a fresh water plant is placed in a salt water tank, what will likely happen to the cells of the plant?

• They will swell because water will move into them.

• They will swell because salt will move into them.

• They will shrink because water will move out of them.

• They will shrink because salt will move out of them.

If energy is needed to move materials into or out of a cell, what is most likely occurring?

• active transport

• passive transport

• osmosis

• diffusion

How are prokaryotic and eukaryotic cells similar?

• Both contain a nucleus.

• Both contain ribosomes.

• Both contain membrane-bound organelles.

• Both contain cell walls.

These diagrams represent a Euglena and a Paramecium. Which function do structures X and Y have in common?

• digestion

• gathering food

• movement

• reproduction

Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?

• Substances are moving rapidly across the cell membrane.

• ATP is being rapidly consumed near the cellular membrane.

• Substances are moving from high to low concentrations.

• Substances are moving through channels in the cell membrane.
