is the next inner whorl and is often coloured brightly. The individual units of corolla are called petals . They serve to attract bees, birds, etc which are the agents of pollination. ..

The stem is also swollen but it is branched. The scaly leaves are bigger. For example: Ginger, Turmeric etc. Rhizomes also give rise to new plants from the axillary b..

It is seen in certain fungi and multicellular animals. In budding, the parent cell or body gives out a lateral outgrowth called the bud. The nucleus divides and one of the daughter nuclei passes into the daughter cell. The bud grows in size while being attached to the parent body. It then gets sep..

Pollination leads to fertilisation, resulting in the production of seeds and fruits, thus ensuring continuity of life...

Sterilisation is a surgical procedure that involves cutting of the tubes that conduct the gametes. Vasectomy - Sterilization of Man In males it is called vasectomy in which each vas deferens is cut and the cut ends are tied back. Tubectomy - Sterilization of Women In females, it is called ..

Fertilisation - Fertilisation can be defined as the fusion of the sperm nucleus with the egg nucleus to form a diploid cell known as zygote. The fertilisation is internal in the human reproductive system. It is achieved by the insertion of the male organ, penis into the vagina of the fema..

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..

The stem is swollen and the nodal regions are called the eyes. For example: Potato The Formation of Axils and Development of Aerial Shoots in Potato Each eye has scaly leaves and axillary buds which develop into new plants when the tuber is plante..

The stem is very small and disc-like. For example: Onion, Garlic, Lilies, etc. Diagrammatic Section through a Dormant Bulb From the stem arise scaly and fleshy leaves which bear buds in their axil..
