The plant cell wall

is a protective structure made of cellulose fibrils.

_____ are found only in plant cells, but _____ are found in both plant and animal cells.

Central vacuoles; ribosomes

Which of the following is part of the endomembrane system?

Golgi apparatus

Which plant cell organelle converts chemical fuel into packets of chemical energy that can power the cell?

Which of the following is a function of the central vacuole?

Storing compounds produced by the cell

Which of the following describes the function of the chloroplast?

The chloroplast converts light energy to chemical energy.

Can you label the structures of a plant cell?

a. central vacuole b. cell wall c. chloroplast d. Golgi apparatus e. smooth endoplasmic reticulum (ER) f. rough endoplasmic reticulum g. nucleus h. mitochondrion

What are the three organelles that plant cells have but animal cells do not?

chloroplast, central vacuole, cell wall

Plant cells have two energy-related organelles. ________________ harness light energy to create sugars and ________________ break down these sugars to create ATP.

chloroplasts; mitochondria

The structural framework in a cell is the

cytoskeleton

Which organelles comprise the endomembrane system of a cell?

endoplasmic reticulum, Golgi apparatus, lysosome

The ____________________ builds compounds, whereas the ________________ breaks things down.

endoplasmic reticulum; lysosome

Which of the following organelles breaks down worn-out organelles?

What carries instructions for making proteins from the nucleus into the cytoplasm?

mRNA

Where in a cell is ATP made?

mitochondria

Where is the genetic information of the cell stored?

nucleus

What structure acts as a selective barrier, regulating the traffic of materials into and out of the cell?

plasma membrane
