Prokaryotes, plants, algae, fungi, and many protists have ______. Animal cells do not.
cell walls
cell membranes
chloroplasts
nuclei
Which of these structures are present in plant cells, but not animal cells?
cell wall and cell membrane
cell membrane and mitochondria
cell wall and chloroplasts
mitochondria and chloroplasts
A student is developing a model to show how most proteins are synthesized in animal cells. Which organelles would be LEAST useful for the student to include in a model?
ribosomes
endoplasmic reticulum
Golgi apparatus
chloroplasts
Instructions for making proteins are coded in the ________ of a cell. In eukaryotic cells, these instructions are located in the ______________________.
cytoplasm, DNA
DNA, nucleus
endoplasmic reticulum, nucleus
chloroplast, mitochondra
Which cell structure is correctly matched with its function?
vacuole: stores material inside the cell
cell membrane: divides the cell into two halves
lysosome: manufactures proteins
ribosome: packages and modified proteins
The cell membrane is made up of a lipid bilayer as shown in the model.
Which of the following describes the structure and function of the cell membrane?
The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell.
The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that allows water to enter the cell.

The pancreas is an organ present in some animals. It produces enzymes that are used in the digestive system of the animal. Which cell structure is likely to be abundant inside pancreas cells?
cell walls, because cell walls cannot be digested by enzymes
chloroplasts, because chloroplasts provide the energy for making enzymes
nuclei, because nuclei contain the instructions for synthesizing enzymes
ribosomes, because enzymes are synthesized on ribosomes
A student is comparing the cells of a prokaryote, an animal, and a plant. Identifying which two cell parts would show that the cell was a plant cell, and not a cell of a prokaryote or an animal?
nucleus and mitochondria
cell wall and chloroplast
cell wall and membrane
cell membrane and mitochondria
