In this video we will be looking at sexual reproduction implants. Did you know that they are an estimated 390,900 plant species known to science? This diversity of plant species is in part due to sexual reproduction. In plants, sexual reproduction is carried out in the flowers. The flowers contain the sexual organs. Let's start with labeling the different parts of the flower. The petals and the seaple help protect the flower bud and can be brightly coloured or scented to attract pollinators. The stem and the receptacle are the parts that connect the flower to the rest of the plant. The stem in is the male part of the flower. It consists of anther, where pollen is produced and the filament which is the stalk that supports the anther. These structures are responsible for the production and the positioning of pollen, the male gametes. The female part of the flower is called the carpal and this consists of three parts, the stigma, a sticky landy four pollen, the style, where the pollen grained as scents and the ovary, where the female gametes or six styles are located. Within the ovary, ovules produce female gametes. So how does pollination work? Pollination is a transfer of pollen from the male anther of one flower to the female stigma of another. Flowers can be pollinated in different ways, by wind and water or by pollinators such as insects, birds and other animals. Flowers pollinated by pollinators are structurally different from those pollinated by a wind or water. Look at the differences in size, scent and colour of the petals and the positioning of the stamen and style. Here are some key differences. Why do you think they are different? Did you know that pollinators are very important to our food supply. They pollinate plants that are responsible for bringing us one out of every three bites of food. Once the plant has been pollinated, fertilization can occur. Fertilization results in the production of seeds. In mature pollen grain containing two male six cells has landed on the female stigma of the same species. The pollen grain grows a pollen tube that goes down the female style to the ovary, where it enters through an opening called the microbiome. The male six cells travel from the pollen grain down to the pollen tube to the female ovule. Here, one male six cell fuses with the female egg fertilizing it. This develops into the seed. The other male six cell attaches to two cells in the embryo sac, forming an endospew. This provides the starchy food for the seed to grow. The ovary in the loggers and becomes a fruit surrounding the internal seeds. The fruit and seeds are dispersed in many ways. Some even by humans, where they will again grow into a new plant under the correct conditions, completing the long cycle of sexual reproduction in plant. So there we have sexual reproduction plant. Pollination has to happen before fertilization. The male pollen is produced in the anther, where it is then dispersed during pollination. The female parts of the flower are the stigma, style and the ovary.
