Detailed explanation-1: -In cross pollinated flowers more pollen grains are produced and cross pollination helps flower to survive in different climatic environment. Cross pollination allows diversity in the species as the genetic information of different plants are combined. Was this answer helpful?

Detailed explanation-2: -Cross-pollination is a type of fertilisation in which sperm from one plant’s pollen (anther) is transmitted to the stigma of another plant’s flower. Cross-pollination produces more new genotypes than self-pollination. It contributes to increased genetic diversity.

Detailed explanation-3: -In contrast, cross-pollination-or out-crossing-leads to greater genetic diversity because the microgametophyte and megagametophyte are derived from different plants. Because cross-pollination allows for more genetic diversity, plants have developed many ways to avoid self-pollination.

Detailed explanation-4: -Cross-pollination is the process of applying pollen from one flower to the pistils of another flower. Pollination occurs in nature with the help of insects and wind. This process can also be done by hand to produce offspring with desired traits, such as colour or pest resistance.

Detailed explanation-5: -Cross-pollination or xenogamy enables the fusion of two genetically distinct plant characters, belonging to the same species. Therefore, it introduces genetic recombination and variations in plants due to the fusion of gametes that are genetically distinct.
