State why red blood cells burst when immersed in pure water but plant cells do not.

2.1.6 State that the cytoplasm of all cells contains structures, limited to ribosomes on rough endoplasmic reticulum and vesicles

2.1.7 State that almost all cells, except prokaryotes, have mitochondria and rough endoplasmic reticulum

2.1.8 Identify mitochondria and rough endoplasmic reticulum in diagrams and images of cells

2.1.9 State that aerobic respiration occurs in mitochondria

3.2.1 State that water diffuses through partially permeable membranes by osmosis

3.2.10 Explain the importance of water potential and osmosis on animal cells and tissues

3.2.11 Explain how plants are supported by the turgor pressure within cells, in terms of water pressure acting against an inelastic cell wall

3.2.2 State that water moves in and out of cells by osmosis through the cell membrane

3.2.3 Investigate and describe the effects on plant tissues of immersing them in solutions of different concentrations

3.2.6 State that plants are supported by the pressure of water inside the cells pressing outwards on the cell wall

3.2.7 Define osmosis as the net movement of water molecules from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution), through a partially permeable membrane

3.2.8 Explain the effects on plant tissues of immersing them in solutions of different concentrations by using the terms turgid, turgor pressure, plasmolysis and flaccid

3.2.9 Explain the importance of water potential and osmosis in the uptake of water by plants
