Chapter 10- Movement Through Membranes

Question 1

Diffusion

Answer 1

Movement of molecules from areas of high concentration to areas of lower concentration

Question 2

Osmosis

Answer 2

Movement of water from a high concentration of water to a lower concentration through a semi permeable membrane

Question 3

Osmoregulation

Answer 3

Control of water and salt level in the cell or the organism

Question 4

Turgor pressure

Answer 4

Force of cell contents against the cell wall in plants

Question 5

Turgid cell

Answer 5

A plant cell in which the plant cells are being pushed against the cell wall due to turgor pressure

Question 6

Plasmolysis

Answer 6

Loss of turgor pressure in a plant cell due to loss of water from cytoplasm

Question 7

Active transport

Answer 7

Absorption of molecules into cells against the concentration gradient, using energy

Question 8

Why do plants use turgor pressure?

Answer 8

To keep upright

Question 9

Where does osmoregulation take place in humans?

Answer 9

Kidneys
