Diversity in Living Organisms Notes

Eukaryotic:

• They are eukaryotic organisms, i.e., they contain a well defined nucleus and membrane bound organelles.

Cell wall:

• Fungal cells are covered with cell wall made up of chitin- a complex carbohydrate. Presence of cell wall is a peculiar feature of plant cells and some unicellular organisms also. Unlike fungal cells, plant cell wall is made up of cellulose while in bacteria [unicellular organism] it is made up of peptidoglycan.

Body organization:

Eukaryotic:

• They are made up of eukaryotic cells, i.e., they contain a well defined nucleus and membrane bound organelles. The important feature of plant cell is that they have special organelle known as plastids. These plastids help:

1. in the process of photosynthesis
2. providing color to the part of the plant
3. storage of different plant products. Also they have large vacuoles and few or no lysosomes unlike animal cell.
