Q

When a cell is in a hypotonic state, the cell…?

A

Has low osmotic pressure (a little bit of water inside of the cell), cell increases in size, and water moves into the cell

Q

When a cell is in a hypertonic state, the cell…?

A

Has high osmotic pressure (a lot of water inside of the cell), it shrinks, and water moves out of the cell

Q

What is the function of the flagellum?

A

Aids in the movement of the cell

18
Q

What is the function of the ribosomes?

A

Site of proteins synthesis

19
Q

What is Transcytosis?

A

Combines endocytosis and exocytosis to selectively and rapidly transport a substance or particle from one end of a cell to the other

20
Q

What is one example of active transport?

A

Sodium potassium pump

21
Q

What is the function of the Rough endoplasmic reticulum?

A

Protein synthesis

22
Q

What is the function of the microvilli?

A

Leads to increase of surface area, increasing absorption

23
Q

What is excocytosis?

A

Substances made in the cell are packaged into a vesicle, which fuses with the cell membrane releasing it’s contents outside of the cell
