Flowering Plant Reproduction

Flower is the site of sexual reproduction in flowering plants. Pollination and fertilization must occur in order to achieve the goal of producing seeds.

Pollination involves the transfer of pollen from Anther to stigma. Pollen mengancung male gamete.

Flowers mostly have Anther and stigma, etapi to generate genetic variation, pollination usually occurs between flowers of different plants.

Pollen can be carried by animals, wind and water. The following are integral parts of the Flowering Plant Reproduction:

When the male gametes and female gametes meet, fertilization occurs. This occurs in the ovary ovules surrounded by. Ova (female gametes) that develops into an embryo fertilized.

Embryos with food deposits and Testa form a seed. Once fully developed, the seeds are scattered, often still in pieces, but far from the parent plant. In the right conditions, the seeds grow into plants bergerminasi and new.

Flowering Plant Reproduction structure which assisted pollination by wind

This plant does not need to attract insects as pollinators. Wind assisted pollination of flowers which are usually small, unattractive, colorless, odorless fragrant.

Maize is one example of plants that require pollination wind

These plants are generally also Unisexsual. Male and female flowers are on different plants or in the plant but different place. Anther pad abunga male looks tergantun at the end of long filaments and release a number of pollen grains of light that brought winds. Stigma in the female flowers are also directed and made a balanced to withstand winds that carry the pollen grains as he passed.

During the trip between the anthers and stigma, male gametes are protected by a thick wall of pollen grains. Pollen wall consists of layers intin inside and outside layers of hard Eksin. When viewed under a scanning electron microscope, appears to look like intricate carvings. This pattern can be used to identify the plant species.

nsects such bees, attracted by flowers as color, odor, and nectar contained in the flowers. When bees crawl into the flower, the bee sprinkle pollen grains.

When bees visit flowers else with the same species, pollen grains move to the sticky stigma. Eksin carved help spores attached to the insect during berpollenasi. Here is a picture Illustration A bee who is looking for nectar in flowering plants:

Fertilization Process In Flowering Plants

When the pollen grains are in strigma, pollen will make the pollen tube grows through the stylus, the ovary wall, and into the inside ovulum. Two male gametes of pollen grains down to the pollen tube. One gametes will join the ovum to form an embryo. One other gametes join pollar core to form the endosperm, which is a supplier of food for the embryo.
