1.
This is when uniform offspring grow from a part of a parent plant. Parent plants sends out runners. Where the runner touches the ground, roots can grow. A new plant is produced even if the runner is broken apart Each new plant is uniform and identical to the parent.
a)
Vegetative propagation
b)
Regeneration
c)
Budding
d)
Fission
2.
This is when a new organism grows by mitosis and cell division on the body of its parent. The bud, or offspring is identical to the parent. The bud, when large enough, can break off of the parent and live on its own.

3.
What type of asexual reproduction is taking place?
Fishermen work hard to catch and remove all the starfish that get into their favorite shell fishing beds and the “underwater farms” where they raise clams and oysters. In the past, they put the starfish into their boats, cut them up with knives, and then throw the pieces of starfish overboard. They thought this would kill the starfish. What they did not know was that each piece of starfish will grow into a whole new animal.
