Eukaryotic Cells + Prokaryotes Cells Flashcards
Eukaryotic cells
Animal and plant cells are examples of eukaryotic cells. Eukaryotic cells all have a cell membrane, cytoplasm,and genetic material that is enclosed in a nucleus.
The genetic material is a chemical called DNA and this forms structures called chromosomes that are contained within the nucleus. All animals (including human beings), plants,fungi,and Protista are eukaryotes
Prokaryotes
Bacteria are single-celled living organisms. They are examples of prokaryotes. At 0.2-2.0um in length prokaryotes are 1-2 orders of magnitude smaller than eukaryotes. You could fit hundreds of thousands of bacteria on to the full stop at the end of this sentence,so you cannot see individual bacteria on an agar plate, you grow many millions of bacteria. This enables you to see the bacterial colony with your naked eye.
Bacteria have cytoplasm and a cell membrane surrounded by a cell wall,but the cell wall does not contain the cellulose you see in plant cells.In prokaryotic cells the genetic material is not enclosed in a nucleus. The bacterial chromosomes is a single DNA loop found free in the cytoplasm
