Plants either reproduce sexually or asexually, depending on the type of plant. In sexual reproduction, two germ cells, or gametes, fuse to create the beginning of a genetically unique offspring. In asexual reproduction, a plant cell splits in two to create a genetically identical offspring.Continue Reading
During sexual reproduction, a male gamete needs to fertilize a female gamete. Depending on the plant, this is accomplished in a variety of ways. In flowering plants, the male and female gametes are located on different parts of the same flower. The sperm, located in the pollen grains, fall on the carpel of the flower, where the female gametes are located. This process occurs because of wind pollination or insect pollination that transports the pollen grains to the female gametes. As a result of this pollination, a fruit is created, which contains the seeds of offspring. In mosses, sexual reproduction can only occur if the male and female plant gametes combine directly. Conifers have two different cones: a male and a female cone. The male cone gives off pollen that the female cone catches.
Asexual reproduction occurs either through vegetative reproduction or apomixis. Vegetative reproduction occurs when a plant's shoots, roots and, sometimes, leaves fall onto moist dirt and take root. In apomixis, unfertilized plant seeds are used to create more offspring. Although asexual reproduction among plants occurs, sexual reproduction is far more common in most plant species.Learn more about Botany
Totipotency refers to a developmental flexibility within plant cells that distinguish them from most animal cells, in that many somatic plant cells can regenerate into entire plants. Two researchers in the 1950s were the first to prove this ability, which has become a fascinating trait in the plant kingdom.Full Answer >
Algae is not a plant, it is a protista; however, it shares many qualities with plants. Like plants, algae can perform photosynthesis.Full Answer >
The seed germination process is a complex process in which the embryonic plant created by sexual reproduction of plants propagates the species by forming a new, independent plant. In order to germinate, the moisture and temperatures must be right. New plants live a short while on the sugars stored in the seed, requiring the plant to start gathering nutrients and moisture from the soil and producing its own food quickly.Full Answer >
According to Biosciences for Farming in Africa, sexual reproduction in plants occurs when pollen from a plant's stamen reaches the stigma of a flower. The pollen contains sperm cells while the stigma holds the corresponding eggs. When the two meet, the sperm cells fertilize the egg, creating an embryonic seed that later germinates into a new plant.Full Answer >
