Discuss
about classification at cellularity – unicellular or multicellular
Broad concept of classification
There is a great diversity in structure,
cellularity, habitat, mode of nutrition
of different organisms in ecosystem. To understand these differences and similarities
between different organisms, we can classify various animals and plants on the
basis of the following parameters.
Cellularity
An
organism can be unicellular or multicellular. The number of cells decides the
structure, metabolic functions and other parameters of organism. The characteristics
of unicellular and multicellular are given bellow .
