It is of two types :
A. Natural Vegetative propagation
1. Vegetative propagation by stem. e.g. grasses, turmeric, onion, colocasia, potato, gladiolus and crocus.
2. Vegetative propagation by roots. e.g., Tuberous roots of sweet potato, asparagus, tapioca, dahlia and yams (Dioscorea).
3. Vegetative propagation by leaves e.g. Bryophyllum, Begonia, Lilium.
4. Vegetative propagation from reproductive organs. Flower buds of century plant (Agave sp.) develop into bulbils.
B. Artificial vegetative propagation.
1. Cutting e.g. leaf cutting in Bryophyllum.
2. Layering e.g. Jasmine.
3. Grafting e.g. Rose, Mango.
4. Micro-propagation.
5. Gootee e.g. lemon, orange, guava, litchi
Examine a few flowers of any cucurbit plant and try to identify the staminate and pistillate flowers. Do you know any other plant that bears unisexual flowers?
Why are offspring of oviparous animals at a greater risk as compared to offspring of viviparous animals?
Why do algae and fungi shift to sexual mode of reproduction just before the onset of adverse conditions?
