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?

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
