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

The stem is very small and disc-like. For example: Onion, Garlic, Lilies, etc. From the stem arise scaly and fleshy leaves which bear buds in their axi..

The stem is swollen and the nodal regions are called the eyes. For example: Potato Each eye has scaly leaves and axillary buds which develop into new plants when the tuber is plant..

These are non-motile spores produced inside structures called sporangia in fungi such as Rhizopus and Mucor. These spores are dispersed by wind. fig. 8.20 - Modes of Asexual Reproduction..

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 female. The sperms ..

It is generally seen in bacteria and most fungi. One of the cells enlarges and forms the sporangium (literally meaning spore sac). The nucleus divides many times and then the daughter nuclei are surrounded with protoplasm bits to form daughter cells called spores. The spores are covered with a thi..

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. Fragmentation in Spirogyra Worms such as ribbon-worms (Nemertinea) and flatw..

Roots of some plants develop new plants either by directly producing shoots or producing buds. Shoots are produced by roots of woody plants like Dalbergia, Murraya etc. Adventitious buds are formed on the roots of plants like sweet potato, dahlia, asparagus, tapioca, etc. These buds detach from the..

The stem is also swollen but it is branched. The scaly leaves are bigger. For example: Ginger, Turmeric etc. Diagrammatic Structure of an Iris (Rhizome) Rhizomes also give rise to new plants from the axillary bu..

This is not very common and is seen in plants such as Bryophyllum. Totipotency Exhibited by BryophyllumIt has succulent (fleshy) leaves and adventitious buds are present at the margins of the leaves. These buds fall off and grow into new plan..
