Although all flowering plants rely on pollination for reproduction, there is a variation in how plants pollinate. There are two types of pollination called self-pollination and cross-pollination. Self-pollination is the more basic type of pollination because it only involves one flower.
If pollen from one plantâs stamen is transferred to the stigma of a different plant of the same species, cross-pollination occurs. Cross-pollination is better than self-pollination because it produces stronger plants. However, the pollen from a different species plant will not work. Once ovules in a plant are fertilized with pollen, the ovules develop into fruit. The fruit covers the seeds, which eventually become new plants. Pollinators
