Prokaryotic
Cell
- The organisms made of
prokaryotic cells are called prokaryotes e.g. bacteria and cyanobacteria.
- These cells lack a membrane
bound nucleus. The hereditary material (DNA) is found in cytoplasm.
- These cells lack membrane
bound organelles.
- Ribosomes are of small size
in and freely scattered cytoplasm.
- Cellulose is absent in cell
wall, rather it is made up of peptido-glycan or murein.
- These cells are simple and
of smaller size (average diameter 0.5 – 10 nm)
Eukaryotic
Cell
- The organisms mae of
Eukaryotic cells are called Eukaryotes, e.g. animals, plants fungi and
protists.
- These cells have a membrane
bound nucleus; and hereditary material is found inside the nucleus.
- These cells have membrane
bound organelles.
- Ribosomes are of large size
and are present in endoplasmic reticulum free in cytoplasm.
- Cellulose is present in cell
wall of plant cells. The cell wall of most of fungi is composed of chitin.
- These cells are complex and
of larger size (Average diameter 10-100nm)
