Essays Bio test 2

Question 1

vegetative propagation

Answer 1

1. cutting: a slip or piece of wood is planted and grows to form another plant that is the same type (faster than a seed)
2. layering: forces a plant to grow roots at another location and then that portion is cut and planted to form a new plant of the same type
3. grafting: uses plants of 2 (typically different) species and fuses them together with the stock at the base and the scion being added
4. budding: form of grafting but only fuses the bud instead of a larger portion of the plant
5. tissue culturing: seedlings are formed from individual cells in a lab

Question 2

pollination and fertilization

Answer 2

pollination: transfer of pollen from the anther to the stigma of a pistil
2. fertilization: when the pollen fuses with the ovules. This allows the ovules to form into seeds
