Aim: How can we describe different methods of asexual reproduction?
Do Now:
• Draw a Venn diagram comparing & contrasting sexual & asexual reproduction
HW Review
• Take out your HW on binary fission and budding.
• Correct your mistakes as we go along.
Summarize in your notes
• How is binary fission similar to budding?
• How is binary fission in a paramecium different from budding in yeast?

Summary
• Name 3 methods of asexual reproduction. Give an example of each.
Aim: How do organisms reproduce with regeneration?
Do Now:
• 1. Draw a Venn Diagram of BUDDING and BINARY FISSION.
Summarize in your notes

HW Review
• Check your homework with a neighbor. (5 minutes)
• If you are still unsure, ask your teachers.
An orange with no seeds!?
Vegetative Propagation
• When stems, roots or leaves give rise to a new plant
Video Clip
• Watch the explanation of vegetative propagation.
• 1) Is this asexual reproduction or sexual reproduction? Why?
• 2) What part of the plant would be needed for sexual reproduction?
