Stock is the lower part of the plant and scion is the upper part of the plant.
The other stem is cut without roots and is called scion. Of the two cut stems, one stem is with the roots and is called stock.
In grafting stems of two different plants is cut and joined in such a way that they grow as on plant. The propagation of Jasmine plant (Chameli) by the layering method. The layering method is used for the plants like Jasmine, Strawberry, raspberry, etc. In this way a new plant is formed from the buried branch. The part of the branch which is inside the soil develops roots and is later cut from the parent plant. In layering the branches of the parent plant are allowed to go inside the soil in such a way that a part of the branch comes out of the soil. The propagation of plants by ‘cuttings’ method. Plants like bougainvillea, chrysanthemum, grapes, etc., can be grown by cutting. After a few days one can notice a new plant growing. This part is then grown into soil and watered. They are:Ī new plant is grown by cutting a small part of a plant which can be a stem or a leaf that has a bud on it. There are three common methods of artificial propagation of plants. When many plants are grown from one plant using man-made methods, it is called artificial propagation. Plantlets growing in the margin of bryophyllum leaf. Vegetative propagation of potato plant from a Potato tuber. Plants that undergo vegetative propagation are green grass, Bryophyllum, money plant, potato plant, onion, banana, etc. The buds which are present in dormant state in old plant are provided with suitable conditions like moisture and warmth so that they grow and develop to form a new plant. In vegetative propagation, parts of old plant like stems, roots and leaves are used to grow a new plant. This form of asexual reproduction occurs in plants only. Spirogyra, a filament type algae plant reproduces by the method of fragmentation. Spirogyra which is a plant and sea anemones which is a sea animal undergoes the process of fragmentation. Each piece than grows into a new organism. In this process the multicellular organism breaks into two or more pieces on maturation. Hydra and planaria undergo regeneration.įragmentation occurs in multicellular organisms, be it plants or animals. Regeneration occurs in both plants and animals. These cells then move to their proper places to form organs and body parts. This happens because when the body of an organism that can undergo regeneration gets cut then the cells of cut body part divide rapidly and form a ball of cells. In this process, if the body of a parent organism gets cut, then each cut part can regenerate and form a whole new organism from its body parts. Regeneration is an asexual method of reproduction. Hydra reproducing by the method of budding. Hydra and yeast undergoes the process of budding. In the process of budding, a small bud grows on the body of parent organism and when the time comes it detaches itself to form a new organism. Plasmodium undergoes the process of multiple fission. When the favourable conditions come, the cyst breaks and the many daughter cells inside it are released. Inside this cyst the nucleus of an organism breaks in many smaller nuclei. This happens when cyst is formed around a unicellular organism. Multiple fission is also a process of asexual reproduction in which parent cell splits to form many new organisms. In this process, after splitting parent cell do not exist and two new organisms are formed.Įxamples of unicellular organisms that undergo binary fission are amoeba, paramecium, Leishmania etc. In binary fission, the parent cell divides into two after reaching a point where it has fully grown.
