Name Type What ? Organisms + -

1. Binary Fission

Asexual Cell splits and replicated DNA goes with each part

• bacteria • fast • easy

• all offspring have same DNA

2. Regeneration/ Fragmentation

asexual Lost or damaged tissues, organs or limbs are restored

Invertebrates• worms • Starfish

• easy • parent broken• same DNA

3. Budding asexual Offspring grows off of parent

•Yeast•hydras

• fast•Some-what easy

•All offspring have same DNA

4. Pollination sexual When pollen is transferred from the anther to the stigma

Flowering plants

• plants don’t have to move• mixes DNA

• need a pollination vector

5. Sexual Reproduction

sexual Egg and sperm unite to form a zygote

Most animals and some plants

• results in genetically differences

• slow

Class Starter Questions1. Draw a picture of a flower and try to label it’s parts as best you can.

2. Can you Identify which are the female and male parts?
