(9 cards)
1
Q
What is necessary for an organism to be multicellular?
A
Cells need to adhere to one another to form tissues.
2
Q
What is responsible for cell adhesion?
A
The plasma membrane.
3
Q
What are the two types of cell adhesion?
A
Permanent or temporary.
4
Q
What are cell adhesion molecules (CAMs)?
A
A type of cell surface protein required for cell adhesion.
5
Q
How do CAMs function?
A
They bind cells with other cells or with the extracellular matrix.
6
Q
What does the extracellular matrix contain?
A
Supporting structures, such as collagen proteins.
7
Q
What is the function of the extracellular matrix?
A
Provides support for the cells.
