• Cells cannot reproduce.

• Cells come from other cells.

• Cells are the basic unit of life.

Nutrients and oxygen enter cells through the:

• cell membrane

• mitochondria

• robosomes

• nucleus

The process by which plant cells produce glucose:

• photosynthesis

• respiration

• protein synthesis

• diffusion

Which statement BEST compares the role of organelles in making proteins?

• Rough ER transport proteins, while cell membrane modifies proteins

• Vesicles modify proteins, while Golgi bodies manufactures

• Ribosomes produce proteins, while the nucleus contain protein blueprints

• Chromosomes modify proteins, while the nuclear membrane produce

Which statement BEST justifies the comparison of a cell’s nucleus to a person’s brain

• Both are encased in a hard, protective coating

• Both are involved in producing energy-containing molecules

• Both store information and control activities

• Both are directly involved in transporting wastes so they do not build up

If the cell membrane could not function properly, what would be the most immediate impact on the cell’s ability to maintain homeostasis?

• Most mitochondria will stop functioning

• The substance in the cytoplasm would change

• Transport along the endoplasmic reticulum would slow down
