Gametes are delicate single cells. For two plants to cross fertilize, there must be a mechanism for the two gametes to reach each other safely. There must also be a mechanism to disperse their offspring far enough away from the parent so that they do not have to compete with the parent for light, water, and soil minerals. The functions of the flower solve both of these problems.

Plants play a key role in the maintenance of terrestrial ecosystems through stabilization of soils, cycling of carbon, and climate moderation. Large tropical forests release oxygen and act as carbon dioxide sinks. Seed plants provide shelter to many life forms, as well as food for herbivores, thereby indirectly feeding carnivores. Plant secondary metabolites are used for medicinal purposes and industrial production.

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination occurs in flowers where the stamen and carpel mature at the same time.

Use the table of pollination syndromes below to determine the likely pollinator for the flowers available in your lab. Observe the fruits available and use the table below to predict which characteristics are related to each of the following dispersal agents.

Of these, more than 260,000 are seed plants. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. Some biologists also consider green algae to be plants, although many others exclude all algae from the plant kingdom and place them in Protista.

It details the processes of pollination and double fertilization, which lead to seed formation containing embryos and food. Furthermore, it describes how fruits, derived from ovary walls, aid in seed dispersal through various methods, contributing to the survival and distribution of the species.
