Ch 7 Cell Structure & Function Review

Which of the following structures is found in the cytoplasm?

• nucleolus

• ribosome

• cell wall

• chromatin

Which of the following contain a nucleus?

• organelles

• prokaryotes

• bacteria

• eukaryotes

Which organelles help provide cells with energy?

• rough endoplasmic reticulum

• Golgi apparatus and ribosomes

• smooth endoplasmic reticulum

• mitochondria and chloroplasts

All of the following are examples of cell specialization EXCEPT:

• muscle cells that control movement of materials in the body

• red blood cells that carry oxygen

• pancreatic cells that produce digestive enzymes

• prokaryotic cells that photosynthesize

You will NOT find a cell wall in which of these kinds of organisms?

• plants

• fungi

• animals

• all of the bove

Which structure makes proteins using coded instructions that come from the nucleus?

• vacuole

• ribosome

• Golgi apparatus

• mitochondrion

Unlike the cell membrane, the cell wall is:

• found in all organisms

• made of tough fibers

• composed of a lipid bilayer

• a flexible barrier

Which organelle breaks down food into molecules the cell can use?

• endoplasmic reticulum

• lysosome

• Golgi apparatus

• mitochondrion

Diffusion occurs because:

• molecules never move or collide with each other

• the concentration is always the same throughout a solution

• molecules constantly move and collide with each other

• the concentration is never the same throughout the solution

An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes:

• water to move into the cell

• solutes to move out of the cell

• solutes to move into the cell

• water to move out of the cell
