We will learn about the types of asexual reproduction. We know that some organisms produce the next generation from single parents like Amiba, Hydra etc. The reproduction in which only one parent participates is called asexual reproduction. Variety of asexual reproduction is found in different organisms. On the basis of it, there are different types of asexual reproduction. Today, let's learn about the types of asexual reproduction. Fishing Some organisms produce new organisms by cell division. We call this method Fishing. Amiba is a unicellular organism. In Amiba, reproduction begins with the division of the nucleus. When division of the nucleus is complete, the cells also divide into two parts. This division can occur from any part of the Amiba. During the division process, each cell carries one nucleus with them. In this way, the formation of two cells by the division of one cell is called binary vision. Some unicellular organisms, such as leshmanias, body structure, is more organized. In such organisms, after the division of the nucleus, the cell divides from a fixed orientation. In some organisms, such as the malaria parasite plus modium, one cell divides in several cells. We call it multiple fission. Fragmentation Some multicellular organisms, such as pyrogyra, which is an early, have simple body structure. Generally, such organisms are just group of different cells. When they are fully grown, they break into small pieces. Each part or fragment develops into a new organism. This method of reproduction is called fragmentation. Body structures of other multicellular organisms are complex. In such cases, there is formation of tissue from cells and formation of organs from tissues. The location of organs is fixed in the body due to which, cell by cell division of these organisms is not possible. Therefore, fragmentation is not seen in such organisms. In such organisms, we see a complex process of reproduction. You must have seen that, lizards separate their tail from body under adverse circumstances. Later, the lizard region rates its tail again. Similarly, in the method of regeneration, if some organisms like Plenarya cut down into different parts, each part develops into new Plenarya. This method of reproduction can also be seen in Hydra. Some organisms such as Hydra have cells with regenerative potential. When the Hydra is fully grown, the regenerative cells divide by creating a bulge that is a bud on the body wall. This bud develops into small Hydra. On sufficient growth, these organisms separate from parent Hydra and become independent organisms. In favorable circumstances, some plants can be grown from their part like root, stem, leaves or buds. This is called as vegetative propagation. For example, carrot, radish, sweet potato, etc. can be grown from the root of the plant, rose, ginger, etc. from the stem of plants. Briophylum can be produced from the leaves of the plants. Sugarcane and various types of grasses can be produced from buds. Candidative propagation can be used in agriculture for the production of grapes, bananas, oranges, jasmine, sugarcane, etc. For this, techniques like layering, grafting, etc. can be used. The method in which a portion of an above ground stem is buried in the soil so as to grow a new plant attached to the parent plant is called layering. Similarly, the method of joining the parts of two different plants so as to grow a new plant is called grafting. Collect information about them yourself. Flowers and fruits can be obtained in less time from plants grown by such technology than from plants grown by seeds. For example, if you take a piece of bread and soak it in water and keep it in a moist and dark place, then within one or two days you will see some thread like structures developing on it. It is a hyphae of rhizopus. If you observe the vertical fibers with a microscope, then you will be able to see a blob on a stick structures on it. These structures are called sporengia. Special cells are found in these structures which are called spores, a thick wall protects the spores. Under favorable conditions, this wall breaks and spores get spread at appropriate temperatures and humidity. These pores begin to grow and form new fungus. This method of reproduction is known as spore formation. Now, you must have understood various methods of asexual reproduction. Today we have learnt the types of asexual reproduction.
