1
Q
What is osmosis
A
Osmosis
is the
diffusion
of water molecules, from a region where the water molecules are in higher concentration, to a region where they are in lower concentration, through a
partially permeable
membrane.
2
Q
Flaccid
A
Water lost from the cell, vacuole shrinks and cell loses shape.
3
Q
Turgid cell
A
Water enteres by osmosis, vacuole swells and pushes against the cell wall

5
Q
Active transportation
A
the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient(requires energy)
