Bacteria Reproduction: Not quite the same!

What type of cells are bacteria?Prokaryotic cells:

Single celledHave a single strand of DNA and

some plasmidsDo Not go through Mitosis or

Meiosis

How do Bacteria Reproduce asexually?

They reproduce asexually through binary fission.

Bacterial Conjugation - Transfer of a Plasmid (Primitive Sexual Reproduction)

How do bacteria reproduce sexually?

They reproduce sexually through conjugation.

How is a eukaryotic cell different from a prokaryotic cell when considering the heredity material?

Prokaryotic cells have a single strand of DNA, not chromosomes. Prokaryotic cells DO NOT go through mitosis or meiosis!

How do viruses reproduce?

Viruses:

What viruses are NOT!

Considered to be aliveAble to metabolize on their ownLive outside of a specific host cellReproduce on their own

In other words they are not LIVING!

Bacteriophage

How are viruses different from both prokaryotic cells and eukaryotic cells?

Viruses can NOT reproduce on their own. They must highjack a living cell!

Prokaryotic and eukaryotic cells reproduce on their own.

How do viruses reproduce?They attach, insert heredity

material, highjack cell, produce more viruses and break out of cell.

How do viruses reproduce?Lytic Stage: Active

How do viruses reproduce?Lysogenic Stage: Latent or

Hidden

Review:How are viruses different from

both prokaryotic cells and eukaryotic cells?

How do viruses reproduce?

How do bacteria reproduce asexually?

By replicating (copying) the single strand of DNA, cell grows and then divides into two cells. This is called binary fission.

How do bacteria reproduce sexually?

Bacteria attach to each other by their pili and exchange plasmid material.

What is the difference between a prokaryotic cell and eukaryotic cells?

Prokaryotic cells do NOT go through the processes mitosis or meiosis!

How are viruses different from both prokaryotic cells and eukaryotic cells?

Viruses are NOT cells, they are not considered living organisms. They can NOT reproduce on their own. They need a specific living host in order to reproduce.

How do viruses reproduce?

A. Attach to a host cell

B. Inject hereditary material into host cell

C. Highjack the host cell making it reproduce more viral material

D. Reassemble viruses and lysis from the host cell
