communicate with other cells

Question 8

Passive Diffusion (3)

Answer 8

Simple - permeable substances

Facilitated - via protein channels that is faster than simple

Osmosis - movement of water

Answer 9

Endocytosis - moving into the cell

Exocytosis - moving out of the cell

Question 10

Autotrophs vs. Heterotrophs (2)

Answer 10

Autotrophs - makes its own food

Heterotrophs - obtain nutrients from eating other organisms or their products
