Reproduction In Flowering Plants
Reproduction In Flowering Plants
Reproduction in flowering plants reproduce differently from other plants that don’t reproduce sexually. Flowering plants are categorized as being either asexual or sexual stage. Both sex and sex reproduction are important in the growth and development of plants. Asexual reproduction is when a plant reproduces by budding. This occurs in plants that have already flowered.
Flowers are the reproductive organs of the plants. Flowers changes into fruits. Fruits have seeds and seeds grow into new plants. Therefore, plants reproduce from seeds present in the fruits but some plants such as ferns and mosses grow from spores as they do not have fruits and flowers.
Parts Of Flower And Its Functions:
1. Sepals: Sepals gives protection to the plants at the bud stage. It is like a leaf present at the flower base.
2. Petals: Petals are used in pollination as it attract insects. They are of sweet smell and brightly coloured for attracting insects.
3. Stamens: They are the male reproductive part of flower. It consists of anthers and filaments. When insects collect nectar from flowers then pollen sticks to their body and this is how insects help in pollination.
Pollination is defined as the the transfer of pollen grains from anther to stigma.
4. Carpel: It is female reproductive part of the flower and is also known as pistil. It consists of stigma, style and ovary. Ovules are present in the ovary. After pollination, pollen tube will grow from pollen grains and reaches the ovary through style.
Fertilization is defined as the fusion of pollen grains with ovules.
How Does Reproduction In Flowering Plants Take Place?
Germination occurs at the division of an individual cell. The division of cells occurs because of some signal such as light, temperature, chemical, or physical. The division of cells occurs without the need for fertilization as in sexual reproduction. Flowering plants take about four weeks to form a sporulation, or new plant grows from the original one. Asexual reproduction takes place after the development of new vegetative cells has stopped and the development of a reproductive organ such as the ovary or sperm.
Flowering plants carry life-giving parts called pollen and seeds. Seeds are responsible for producing new plants by allowing the reproduction process to continue. There are three parts of a flower that carry seeds: stigma, base, and petals. Stem means the upper part of the flower where the seed is stored; base is the middle area on the flower where the seed is stored; and petals are the soft part at the bottom of the flower where the seeds are dropped off. Flowering plants have sepals also.
Separate parts of a flower have different functions. The stigma is usually white in color and the area around it is colored, while the base and petals are either clear or colored. The reproductive part of a flower has a clear or colored ovary which allows the transfer of the sexual reproduction cells.
Flowering plants have many sepals. Each has a reproductive organ called a thysanula, which is present in a thin layer of the flower’s skin. These thysanulas transfer the reproduction cells, or pollen, from one flower to another. Flowering plants have a single thysanula. When the pollen comes in contact with a suitable receptacle on the next flower, the thysanula and the pollen are transferred and new flowers are born.
Flowering plants have a variety of petals that serve as their sexual organs. Flowering plants have two types of petals: stamens and pistils. The stamens, which can be wingless, are used to attract insects. The pistils, on the other hand, contain the reproductive organs.
Flowering plants have parts called stamen and corpus, which differ from other parts of the plant. Flowering plants have these parts attached to the stigma, which is the male organ of reproduction. The parts of the stamen that produce a flower are called stigmas, while the parts that do not produce a flower are called corpus. Most of the living parts of a plant that are not made up of living cells are called apoplasties.
Self-pollination is a process in which insects, which are called pollinators, deposit their eggs at the stigma, or center, of a flowering plant. When the pollen comes in contact with a suitable anther the anther discharges its pollen. The pollen then fertilizes the anther. Self-pollination is common in most flowering plants. A common condition that causes self-pollination is having a short or a wet summers.
An important class of flowering plants are the asexual reproduction. Asexual reproduction occurs when a plant reproduces sexually without the help of any sexual reproduction system. Many types of asexual reproduction plants are pungent. The most common asexual reproduction is that by which seeds are produced without the aid of fertilizers. In angiosperms, seeds are produced by sexual reproduction.
Asexual reproduction does not occur with all flowering plants. Some plants, for example, have a structure, called an ovule, that contains an embryo and develops into a flower before maturity. In such plants reproduction is through sexual reproduction.
The process of vegetative reproduction is also called sporogenesis. It occurs in certain species of algae when the algae cells divide before the sporulation of the new organism occurs. This division of the algae cells is called sporulation. When this process occurs, the new organisms is called zooids. Most of the algae cells divide and form nooks and crannies where the new organisms settle and form a variety of vegetative microorganisms.
