Q

Peroxisomes

A

Have enzymes that destroy harmful substances produced in metabolism

17
Q

Rod shaped bodies near the nucleus that function in cell division. They help to organize the cell and divide the cell contents during this process

A

Centrioles

18
Q

What effect does isotonic have on a cell?

A

None, cell in equilibrium with its environment.

19
Q

Hypotonic

A

Has a lower concentration of dissolved substances then the fluid in the cell
Think hypo lower

20
Q

Hypertonic

A

Has a higher concentration of dissolved substances then the fluid in the cell
Hyper-higher

21
Q

What effect does hypertonic have on cells

A

Cell will lose water and shrink cell undergoes crenation

22
Q

What effect does hypotonic have on cells

A

Cell takes in water swells and may burst red blood cell undergoes hemolysis

23
Q

What is phagocytosis

A

Large particles are engulfed by the plasma membrane and moved into the cell. Material taken into a cell by phagocytosis is first enclosed in a vesicle made from the plasma membrane and is later destroyed by lysosomes
