Cellular Reproduction

1
Cellular Reproduction

• There are two types of cellular reproduction
• Asexual reproduction
• Sexual reproduction

2
What is asexual reproduction?

• Reproduction in which a single parent produces
  offspring that are genetically identical to the
  parent (a clone).

Asexual Reproduction

• 1. All three processes begin with the same phase
  INTERPHASE
• During interphase
• Cell grows
• DNA replicates
• Prepares for mitosis if eukaryotic cell

5
Eukaryotic vs. Prokaryotic

• Eukaryotic cells go through an extra phase
• MITOSIS
• Why dont prokaryotic cells go through mitosis?

6
4 stages of mitosis

• What do you start with?
• What do you end up with?

7
Last Phase

• All cells go through cytokinesis.
• Cytokinesis is the process of splitting the cell
  into 2.
• How it splits can be different.

8
Asexual Reproduction Processes

• The cell can be split in different
• ways
• Binary Fission (prokaryotic cells)
• Budding (eukaryotic cells)
• Fragmentation
• (eukaryotic cells)
• Regeneration

9
Binary Fission

• Occurs in prokaryotic cells
• Does not involve mitosis

10
Budding

• Occurs in eukaryotic
• cells
• Offspring grows off
• the body of the parent
• Includes mitosis

11
Fragmentation

• Part of an organism is broken
• off the piece can grow a
• new identical organism.

12
Regeneration

• A piece of the body can grow back after removed.
• If there is enough genetic material in the part
  removedit can then grow into a new identical
  copy of the original organism.

What is happening from start to finish as this
cell reproduces asexually?
