All living organisms have MRS.
GREN-Movement, respiration, sensitivity,
growth, reproduction, excretion and nutrition
Some protoctists, such as Amoeba, have features like an animal cell. Others, such as
Chlorella, have chloroplasts and are more like plants. Some protoctists are pathogens.
For example, Plasmodiumis, the pathogen that causes malaria. They are also single celled.
Animals are multicellular organisms – they consist
of many cells that work together. Examples of
animals include mammals
Plants are also multicellular organisms – they
consist of many cells that work together.
Examples include cereals (such as maize),
and peas and beans.
Mushrooms, toadstools and moulds
(such as Mucor) are multicellular fungi.
Yeast is an example of a single-celled
fungus.
All living things are classed into 5 kingdoms Protocitsts, prokaryates, fungi, plants and animals.
After thaat they are classed in the following order-Phylum, class, order, family, gunus and
species
Prokaryates are bacteria or
blue-green algae. THey are single
celled.
Individuals in a population are usually similar to each
other, but not identical. Some of this variation within a
species is genetic, some is environmental, and some is
a combination of both.
The genetic information comes
from mother and father.
There is species variation like gold
fish and clown fish
