1

What is the function of the cell membrane?

Regulates what goes in and out of the cell

2

What are the 4 types of passive transport?

Simple diffusion, osmosis, filtration, and facilitated diffusion

3

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

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

4

What is endoytosis?

Large partices enter a cell are conveyed in a cesicle that froms from a section of the cell membrane

5

What are some characteristics of active transport?

It requires ATP and compunds moves from an area of low concentration to an area of high concentration

6

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

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

7

What is the function of the Lysosomes?

Destroys any cellular debris or damaged cells

8

What is the function of the cytoplasm?

Allows for movement of objects in the cell

9

What are some characteristics of passive transport?

It requires no ATP and compounds move from and area high concentration to and area of low concentration

10

What is the function of the Smooth endoplasmic reticulum?

Synthesis lipids and drug breakdown

11

What is the function of the Nucleus?

Regulates cellular activity

12

What is the function of the golgi apparatus?

Modifies, transports, and packages different substances, such as proteins

13

When a cell is in a isotonic state, the cell...?

Has equal osmotic pressure, no net movement of water

14

What is the function of the mitochondria?

Site of cellular respiration; produces ATP

15

What is the function of the nucleolus?

Ribosome production

16

What is the function of the cilia?

Aid in the movement of substances through passage ways

17

What is the function of the flagellum?

Aids in the movement of the cell

18

What is the function of the ribosomes?

Site of proteins synthesis

19

What is Transcytosis?

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

20

What is one example of active transport?

Sodium potassium pump

21

What is the function of the Rough endoplasmic reticulum?

Protein synthesis

22

What is the function of the microvilli?

Leads to increase of surface area, increasing absorption

23

What is excocytosis?

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