Answer 1

the two types of cell are prokaryotic and eukaryotic.

prokaryotic cells are simpler than eukaryotic cells.
prokaryotes include bacteria and blue-green algae.

Eukaryotic cells are more complex and include all animal and plant cells.

Question 2

what are the differences between prokaryotes and eukaryotes

Answer 2

prokaryotes :
. extremely small cells (0.5-3.00 um diameter)
.no nucleus -DNA free in cytoplasm
.cell wall made of polysaccharide, but not cellulose or chitin
.few organelles
.small ribosomes
. examples include - coli bacterium

eukaryotes:
.larger cells (20-40 um diameter)
.nucleus present
.cellulose cell wall (in plants and algae) or chitin cell wall (in fungi)
.many organelles
.larger ribosomes
.example- human liver cell
