1. Binary Fission How single cell organisms reproduce
This process is sometimes referred to as “cell division”, where one cell turns into two identical cells
The cell uses mitosis in order to replicate its DNA and splits.
THE CELLS ARE IDENTICAL
Happens quickly… and does not take a lot of energy

2. Binary Fission

3. Fragmentation/ regeneration
Fragmentation or Clonal Fragmentation is a form of asexual reproduction or cloning where an organism is split into fragments. The splitting may or may not be intentional. Each of these fragments develop into mature, fully grown individuals that are a clone of the original organism. If the organism is split any further the process is repeated.
Fragmentation is seen in many organisms such as molds, some annelid worms, and starfish. Binary fission of single-celled organisms such bacteria, protozoa and many algae is a type of fragmentation.
Molds, yeast, and mushrooms, all of which are part of the Fungi kingdom, produce tiny filaments called hyphae. These hyphae obtain food and nutrients from the body of other organisms to grow and fertilize. Then a piece of hyphae breaks off and grows into a new individual and the cycle continues.
Fragmentation is observed in nonvascular plants as well, liverworts and mosses.

4. Budding Asexual Offspring grows out of parent Yeast, hydras
+ Fast, somewhat easy
- No variation

5. Pollination Sexual Pollen is delivered to female part of plant
Flowering plants
+ Plants don’t have to move, mixes DNA to provide variation
- Need external source for pollination to take place; wind, bee, bat, butterfly etc.

6. Pollination

7. Sexual Reproduction Sexual DNA from 2 individuals merge to form one
Animals, Plants
+ Diverse DNA (variation in species)
- Takes a long time, 2 individuals needed
