differentiate between pollen germination and seed germination (side by side difference) (4points)
Answers
Answer:
Pollination and Fertilization occur in plants during reproduction. They are the two main and natural process of producing offspring. Both the process occurs in all flowers, in which both the reproductive structure (anther and stigma) are involved. Therefore flowers are considered as the reproductive organs of all flowering plants.
Answer:
(1) Reserves are used partly to produce molecules to resist desiccation and partly to sustain the first phase of germination. (2) Pollen desiccation may occur in the anther before dehiscence, during presentation, or during dispersal. (3) Pollen and seeds lose water, depending on relative humidity, to a level typical of the species. The water content reached and the possibility of maintaining it distinguish the categories of orthodox and recalcitrant. (4) Orthodox seeds and pollen have a longer mean life and succeed in germinating at greater distances from the mother plant.
