Dispersal by Water Aquatic plants and plants growing on river banks and seashore have fruits and seeds which are dispersed through water They have usually fibrous tissue for floating on water surface, and protective devices so that the embryo may not be damaged Fruits of cocoanut, Nipa (B Golpata) are common examplesCan be easily stored for future usage Long term viability of most of the seeds Apomixis Apomixis is a mechanism to produce seeds without fertilization This mechanism produces clones, hence can be considered as a form of asexual reproduction Apomixis can occur in a number of ways, some of which are mentioned below(a) It is the only method of reproduction in seedless plants like banana, orange etc (b) The plants produced by this method can bear flowers and fruits earlier than those that are produced by seeds (c) It is a short cut method for rapid multiplication
The seed must be implanted into the soil with a distance of 2 feet between each seed The plants propagate through seeds The seeds can initially be grown in a greenhouse and then transferred to the soil at the seedling stage This crop is considered to be selffertile and can also propagate through pollination by insectsAsexual Reproduction The process in which only one parent is involved in the production of new individuals of the same kind is called asexual reproduction In plants, asexual reproduction results in the formation of offsprings or new plants without seeds or spores Asexual reproduction in plants occurs through the following methodsHello, BodhaGuru Learning proudly presents an animated Science video in Hindi for children, which explains how plants reproduce without a seed like potato pl
