Plants are the creatures that compose the beauty of the earth and also can grow virtually all over except the open seas as well as the posts. Although reproduction, which is the common feature of all living points, is not required for the continuation of specific life, it is necessary for the continuation of the living types. In our write-up, information is given regarding the recreation, fertilization, germination and growth stages of plants.
Recreation is the production of a living being of the same species as an outcome of mating with living points of the same species, in order for all living points on earth to continue their generation. Reproduction, which is the common function of all living points, is not essential for the continuation of individual life; however it is necessary for the continuation of the living varieties.
Generally, there are two kinds of recreation in living things: sex-related reproduction and also nonsexual recreation. Plants have a life process, whether they live long or short. With the end of winter months as well as the look of springtime, the turf begins to grow from the soil. When the moment comes for the establishing and also growing plant, they spread several of their seeds on the soil.
By doing this, plants can be located around them that allow their own kind to grow by the technique of reproduction. Recreation or fertilizing in plants is not meiosis; It takes place in the primary stage of mitosis, which establishes after meiosis. The name offered to this period; is monopolydevelopment. reproduction in plants; It creates in different ways in flowering plants and also non-flowering plants.
Reproduction in Non-flowering Plants
Almost all non-flowering plants create spores. Spores germinate to create gametophytes. Throughout recreation, sexual as well as asexual reproduction takes place one after the other. They vary amongst themselves in recreation in non-flowering plants:
- In algae in water, zygotes form spores by meiosis. Haploid period is observed in such algae.
- After fertilization in mosses, the zygote is created. By mitosis from the zygote, sporophyte plant gametophytes are created as well as begin to establish on the plant. They produce spores on the plant by meiosis. Subsequently, these spores germinate by mitosis as well as ultimately form a gametophyte plant. A haploid duration is likewise observed in the recreation of mosses.
- The zygote, which is formed as an outcome of fertilizing in the weeds that we understand as makeshift yards and which are seen in wealth, develop the sporophyte plant thanks to the succeeding mitotic departments. The resulting sporophyte can photosynthesis. The spore sacs on the sporophyte germinate by meiosis and the gametophyte is formed. A diploid period is observed in the reproduction of makes shif.
Reproduction in Flowering Plants
In blooming plants, the component of the blossom is the area where the body organs that will create sexual recreation are located. In female organs, there are several seeds in the ovary. Inside the seeds are megaspore cells. Megaspore cell experiences both meiosis and mitosis; It develops the 8-nucleated embryo sac in the egg. In the male organ, there are microspore cells inside the plant pollen cavities.
This microspore, likewise known as plant pollen mother cell, produces 4 microspore cells by meiosis. Each of these 4 microspores goes through mitosis as soon as well as ends up being 2 nuclei. These 2 nuclei are called pollen. Among the centers in the plant pollen undertakes mitosis as well as sperm is created. The continuing to be center creates the pollen tube after the pollination phase.
When the reproductive body organs are like this; reproduction occurs as complies with: Pollen can be transferred from male plant to female plant by various factors (wind, rainfall, water, bugs). This movement is called pollination. Among the cores of the sperm brought by the pollen tube feeds the egg cell and creates the zygote. The zygote undertakes mitosis to form the embryo. Beyond the developed embryo, there is the ovule of the seed. The seed sac that develops after fertilizing develops the bacterium membrane layer and the bacterium sac.
Let’s briefly compose the parts of the blossom and also their role in reproduction;
- Flower Stem: The part that connects the flower to the plant body.
- Flower Tray: The part on which the petal, sepal, male and female organs are located.
- Sepals: When the flower becomes a bud, it protects from external effects.
- Petals: These are the colorful petals of the flower that we see. These eye-catching colors serve to attract insects.
- Male Organs: It is the structure that is located between the petal and the female organ and consists of two parts, namely the pedicel and the pedicel.
- Head: It is the part where the pollen is located.
- Petiole: It is the part that carries the head.
- Female Organ: This structure, consisting of stigma, stigma and ovary, is located in the innermost part of the flower.
- Hillock: It is the first part of the pollen to settle on the female reproductive organ.
- Pharynx Tube: It is the tube through which pollen is carried from the stigma to the ovary.
- Ovary: It contains the ovules of the seeds. Inside these germs is the female reproductive cell, the egg.
How Does Germination and Development Happen in Plants?
The developing stage happens right away after fertilizing. In other words, the embryo has not yet divided from the mother plant. As the zygote splits; leaves, chins, origins and also stems are developed. Its nutrition is provided by the endosperm from the seed. The young plant that is created remains to feed the plant draft up until it begins to produce enough food for itself thanks to photosynthesis. Germination occurs when appropriate problems such as humidity, temperature level and oxygen are supplied. When the suitable environment is supplied; The seeds swell by taking the provided water as well as the enzymes are activated. Hence, while mitosis proceeds quickly; mobile respiration is also increased.
When mitosis speeds up, the very first root occurs. Afterwards, the initial leaves and stem growth are seen. If the ambient light appropriates; photosynthesis begins. The plant, which undertakes this growth in a specific time period, at some point supplies the formation of blossoms. Plants continue to expand throughout life. Leaves fall and brand-new ones arise. Newly created plants produce brand-new embryos by brand-new fertilizing. This is just how the life cycle of plants occurs.
