Improper pruning has no effect on the branch collar.
Improper pruning will strengthen the branch collar.
4. What is the primary function of a leaf?
, Respiration
Photosynthesis

5. What is the definition of asexual reproduction in plants?
The growth of new plants from seeds.
The process of fertilization between male and female gametes.
Propagation not involving the fusion of gametes.
The method by which plants produce seeds.
6. The removal of dead and damaged branches, along with a general thinning
of the branches to allow easier passage of light and air is known as:

Humidity only affects flowering plants.
Humidity determines soil nutrient content.
Humidity has no effect on plant growth.
Humidity influences transpiration rates and water availability for
plants.
13. Girdling is a process by which
plants carry nutrients downward.
a tree is killed by interrupting the passage of phloem sap.
plants carry water upward.
a tree is killed by interrupting the passage of xylem sap.
plants carry nutrients upward.
