asexual reproduction of a plant

The plant body is not differentiated into stem, root and leaves but is in the form of an undivided thallus. Vascular tissues are absent. The reproductive organs are single-celled and there is no embryo formation after fertilization. This division includes three sub-divi..

. Tutor The two components are abiotic & biotic components. Physical components like light, soil, water, air & temperature are abiotic and plants & animals including humans are the biotic components. Tutor How are animals classified? Tutor vertebrates and invertebrates Tutor Cell division..

Mitosis becomes significant for the following reasons. Mitosis forms two daughter cells which will have the same chromosome number and same genetic material as the parent cell. Daughter cells formed from mitosis are genetically identical to their parent cell and no variation would be introduced dur..

. Some amount of variation is always seen and these appear more pronounced for species that reproduce sexually, when compared to those having asexual reproduction. All the plants of wheat in a field seem one and the same at harvest time. But if you view a litter of pup..

Modes of reproduction in plants can be grouped into 2 types a) asexual b) sexual reproduction Regeneration of new plants from portions of vegetative organs is very common. Runner, rhizome, bulbs, corns and tubers serve as means of propagatio..

Fission occurs in lower plants and animals such as the bacteria, blue-green algae and protozoa. In this process, the cell divides after the genetic material has divided. If the cell divides into two it is called binary fission. The DNA or the nucleus of a mature cell divides first and th..

The offsprings are genetically identical and therefore advantageous traits can be preserved. Only one parent is required which eliminates the need for special mechanisms such as pollination, etc. It is faster. For example, bacteria can multiply every 20 minutes. This helps the organisms to incr..

Production of offsprings by a single parent without the formation of gametes is called asexual reproduction. It is also called as somatogenic reproduction..

Reproduction occurs by vegetative propagation, asexual and sexual reproduction. Vegetative propagation through artificial method can be done by cuttings, layering and grafting. Pollination refers to the transference of pollen grains from the anther of a flower to the s..

Cloning of Organisms - Two or more individuals with identical genetic make up formed from one parent by asexual reproduction are called clones. For example, daughter plants produced by strawberry runners and whole plants produced by tissue culture are clones...
