Answer:
Only plants with perfect flowers are capable of self-fertilization.
Explanation:
Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.
However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.
