Do Flowering plants reproduce sexually or asexually?
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. During sexual reproduction,…
What are the changes in a flower after fertilization?
Fertilization. Flowers attract insects and birds or else rely on the wind or another medium to take the male gametes in the form of pollen from the male flower to
How is an egg fertilized in a flowering plant?
Fertilization. The pollen tube expands down the style to the opening of the ovary and deposits the sperm at the egg. The sperm and egg each contain half of the genetic material needed to form a new plant. When they combine, the sexual union is complete and the egg is fertilized. The fertilized egg will develop into a plant seed.
What happens to the flower after fertilization?
After fertilization is achieved, the flower petals are no longer needed, so they wither and fall away. The ovule develops into a seed, enclosed in its protective seed coat. In many species, the ovum develops into fruit. Both the seed coat and the fruit protect the seed and aid in seed dispersal.
How does sexual reproduction take place in flowering plants?
Sexual reproduction in flowering plants involves the production of male and female gametes, the transfer of the male gametes to the female ovules in a process called pollination. After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit.
Where is in flowering plants does sexual reproduction take place?
Sexual reproduction in flowering plants centres around the flower . Within a flower, there are usually structures that produce both male gametes and female gametes. Inside the ovary there may develop one or more ovules.
How do flowering plants produce male gametes?
Formation of male gametes. In the anthers of a flower, certain diploid cells undergo meiosis, forming haploid spores (called microspores —”little spores”). These microspores divide by mitosis to form two-celled pollen, consisting of a tube cell and a generative cell. If the pollen reaches a receptive stigma (female plant part), the pollen germinates.
