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.Know More
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

Plants with red leaves can range in color from a brilliant red to a deep burgundy, according to Shrubland Park Gardens. The Japanese maple, for example, has purple leaves that turn brilliant red in the fall. This small tree grows very well in a well-drained pot in the garden. The Japanese fern also makes an interesting display with a dark red stripe running down the center of its metallic-looking leaves.Full Answer >
