Cells Review and Practice

Multiple Choice

What purpose does a cell membrane play in eukaryotic cells?

• It digests waste.

• It maintains homeostasis.

• It translates cellular proteins

• It creates energy to fuel cell processes.

Multiple Choice

What organelle in a plant cell generates the ATP energy the plant uses to grow?

• chloroplast

• vacuole

• mitochondrion

• ribosome

Multiple Choice

What is the function of chloroplasts?

• Chloroplasts chemical energy into light energy for immediate use in the cell.

• Chloroplasts convert light energy into chemical energy for immediate use in the cell.

• Chloroplasts convert chemical energy into light energy for later use in the cell.

• Chloroplasts convert light energy into chemical energy for later use in the cell.

​A bacteria's rigid cell wall is primarily composed of a substance called peptidoglycan (also known as murein), which provides structural support

Multiple Choice

Which cells contain a rigid cell wall?

• heart cells

• skin cells

• amoebas

• bacteria

Multiple Choice

What is the purpose of the thylakoid membranes in the chloroplast?

• to increase the amount of DNA present

• to maintain energy production

• to decrease surface area for light release

• to increase surface area for light absorption

Multiple Choice

Where is glucose synthesized in the cell?

• stroma of the chloroplast

• matrix of the mitochondria

Multiple Choice

• DNA replication occurs in the nucleus.

• 
  Translation occurs in the mitochondria.

Multiple Choice

What is the function of ribosomes?

• to provide energy for cellular respiration

• to speed up chemical reactions

• to transport molecules

• to synthesize proteins

Multiple Choice

What would most likely happen if the nucleus failed to make ribosomes?

• Protein synthesis would stop.

• The cell membrane would harden.

• Vacuoles would fail to retain water.

• The cytoplasm would thicken.
