Introduction: Angiosperms are the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species. Most crop and ornamental plants are angiosperms. Their success results, in part, from two innovative structures: the flower and the fruit. Flowers are derived evolutionarily from modified leaves. The main parts of a flower are the sepals and petals, which protect the reproductive parts: the stamens and the carpels. The stamens produce the male gametes, which are pollen grains. The carpels contain the female gametes, which are the eggs inside ovaries. The walls of the ovary …show more content…
Showing the advantages and disadvantages of asexual and sexual reproduction in plants. Asexual Reproduction Sexual Reproduction
Advantages Only one parent needed Mix of the gene pool can produce diversity. It requires less energy compared to sexual reproduction. Offspring can be dispersed widely in different places from their parents. Asexual reproduction gives the ability to produce large quantities of offspring. The off springs all vary from one another and the parents-better adapted to the new conditions due to their different genetic make-up. It enables the plant to spread and colonize an area in short period of time. It helps natural selection remove harmful mutations from the population.
Disadvantages Asexual reproduction usually leads to struggle for existence as well as overcrowding. Requires two parents to mate- requires more energy Unfavorable conditions such as extreme temperatures can wipe out entire colonies. Slower reproduction rate- Plants raised through seeds have long juvenile period. It takes long time to fruiting Results in an exact replica of the parent plant - if the parent has a genetic disease, offspring do too The improved characteristics of a particular cultivar cannot be perpetuated in plants raised from
