Question

2. Sketch and label the diagram showing self- and cross-pollination.

Answer 1

Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). ... Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma.( It is self pollination)
(Cross pollination) pollination of a flower or plant with pollen from another flower or plant.
