Q
What is the function of lysosomes?
A
- contains enzymes that break down materials that are take down into the cells or break down worn out cell parts.
2
Q
What is the function of the cytoskeleton?
A
- consists of microfilaments and microtubules that give the cell it’s shape and assist the movement of materials, organelles or the whole cell.

- modify proteins and package them in vesicles for secretion from the cell.
7
Q
What is the function of the cell membrane?
A
- semipermeable membrane that separates the inside of the cell from surrounding cells and determines which substances get into or out of the cell.
8
Q
What is the function of the cytoplasm?
A
- thick fluid in which all of the structures within the cell are suspended in.
9
Q
What is the function of the centrioles?
A
- a pair of cylindrical structures that are involved in the reproduction of cells.
10
Q
What is the function of the endoplasmic reticulum?
A
- pair of parallel membranes that are used for providing a surface for reactions to take place and it’s channels are used for the storage and transport of materials.
11
Q
Why are cells so small?
A
Increases surface area to volume ratio so that they are more efficient.
