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 then the cel..

In some higher fungi, several hyphae may become interwoven to form rope-like structures called rhizomorphs. Under favourable conditions, they resume growth to give rise to new mycelia. fig. 8.19 - Modes of Vegetative Reproduction..

When the plane of cytoplasmic division coincides with the longitudinal axis of the individual, the fission is called longitudinal binary fission. Example: Euglena Binary Fission in Amoe..

This is a special type of germination found in mangrove plants. Mangrove plants are found in marshy areas and on the sea coast. In viviparous germination, the seeds germinate while still attached to the parent plant. The embryo grows out of the seed and then out of the fruit and projects from it in..

The branches that arise from the stem which is very close to the surface of the ground break off from the parent plant and develop new plants. These branches are classified as follows: Runners - For example, strawberry, grass, etc. Strawberry Runner Suckers - For example, mint, Chrysanthemum ..

The stem is very similar to tuber but they do not have definite shape. For example: Amorphophalus, Colocasia, Gladiolus, saffron, etc. Vegetative Propagation by Underground C..

Neuruletion is followed by organogenesis. During this stage, various organs of the foetus are established and they become functiona..

It takes place in some lower plants and animals such as some worms. The mature organism breaks up into two or more pieces or fragments. The fragments then grow into complete organisms. For example: Spirogyra , an alga. Worms such as ribbon-worms ( Nemertinea ) and flatworms ( Turbellaria ). ..
