Question

A student is creating a T chart of prokaryotic vs eukaryotic cells

Answer 1

T chart of prokaryotic cell vs eukaryotic cell.

Prokaryotic cell

1. size is generally small ( 0.5-10um ).
2. Nuclear region is not surrounded by nuclear membrane.
3. Membrane bound organelles such as mitochondria, Lysosomes, endoplasmic reticulum are absent
4. nucleus is absent.
5. cell division is by fission or budding ( but no mitosis ).
6. they always have single chromosome.
7. DNA is circular and lies free in the cytoplasm.
8. DNA is nàked( not associated with proteins or RNA to form chromosome) eg - found in PPLO bacteria and blue green algae.

Eukaryotic cell

1. they are larget in size (1-100um)
2. Nuclear region is surrounded by a nuclear membrane.
3. all the membrane bound organelles are present.
4. nucleus present.
5. cell diviis mitotic or meiotic.
6. they have more than one chromosome.
7. DNA is linear and contained in a nucleus.
8. DNA is associated with proteins and RNA to form chromosomes. e.g found in plants and animals other than PPLO and blue green algae.
