Osmoregulation VS Osmoconformers

Organisms who are Osmoregulators:

-Birds -Insects -Mammals

Three specialist structure which control osmoregulation:

-Contractile vacuole -Malpighian Tubule -Kidney

Which nitrogen containing product is the most toxic?

Ammonia

Osmoconformers

An organism that allows its internal salt concentration to change with the salinity of the surrounding water

Organisms who are Osmoconformers:

Any marine invertebrates

Three group of animals which have the greatest ability to conserve water:

Mammals, birds and insects

Osmoregulation

Regulation of solute concentrations and water balance by a cell or organism

Similarities between all three specialist structures:

They use osmosis to remove excess water from the organism
