Question

How do plants that depend on cross pollination, prevent development of their own pollen on their stigma? What is this phenomenon called?​

Answer 1

Self-incompatible plants can be thought of as the opposite of the fate of organ transplants in animals. A transplanted organ will be rejected if its genetic makeup is different from that of the host but is more likely to be accepted if the genetic makeup is similar. In the case of self-incompatible plants, genetic relatedness between pollen and stigma results in rejection of pollen, and genetic unrelatedness results in acceptance.

I hope this helps a little.

Answer 2

Explanation:

Abiotic pollination uses nonliving methods such as wind and water to move pollen from one flower to another. This allows the plant to spend energy directly on pollen rather than on attracting pollinators with flowers and nectar.
