7) Exocytosis is an example of what type of transport?
down its concentration gradient
both A and B
Exocytosis moves substances out of the cell.
A plant's roots use osmosis to absorb water from the soil.
active transport
It is easier for small molecules to diffuse across the cell membrane.
water
endocytosis
