Cell Transport

Question 1

Diffusion

Answer 1

Materials move from an area of higher concentration (crowded) to lower concentration (less crowded)

Question 2

Goal of Diffusion

Answer 2

Equalibrium

Question 3

Osmosis

Answer 3

Diffusion of water: High concentration of water to low concentration of water

Question 4

Hyper

Answer 4

“above” more water inside cell so it shrinks: Hyper-tonic water moves outside the cell

Question 5

Hypo

Answer 5

“below” less water in cell so it swells: Hypo-tonic more water moves inside the cell.

Question 6

Iso

Answer 6

“equal” same amount of water as cell so it stays the same: Iso-tonic water going in and out of a cell.

Question 7

Selective Transport

Answer 7

Uses channel proteins to move larger molecules across the membrane sometimes uses energy
Diffusion- no energy, through membrane

Question 8

Homeostasis

Answer 8

Variables within an organism are regulated so that internal conditions remain stable and relatively constant.
