Why do you think the bud was able to grow in the cut of the bark? What
procedures in the lab help the bud to begin growing on the seedling?

What will be an ideal response?

Question 2

Why do you think the seeds need to be exposed to a moist cold environment
before they will germinate? (Hint: Think about fruit trees and their seeds as
they evolved in the natural world.)

What will be an ideal response?

Answer to Question 1

The bud is provided with water and nutrients it needs for growth from the seedling.
Wrapping the shoots in cool moist towels keeps the vascular tissue from drying out
so that when the tissue is reunited with a source of nutrients, it is able to function.
The sharp knife reduces the amount of tearing of bud tissue; sliding the bud into the
bark and tightly wrapping it with budding rubber reduces drying and promotes the
growth of the two tissues together

Answer to Question 2

The moist cold temperatures simulate the environmental conditions of winter. Seeds
that are able to overwinter before germinating may not have to compete with as
many members of the parental generation. Parent plants that die in winter make
space available for new seedlings in the spring.
