Question : Plants propagate normally through seeds. What are other ways that plans propagte through ? Give examples.

Answer»

Solution :Asxeual reproduction takes place by six different method. They are
1) fission 2) budding 3) spore formation 4) regeneration 5) fragmentation and 6) vegetative propagation.
1) Fission : Single called organisms split into two equal offsprings or more offsprings. Ex : Paramoecium BACTERIA.
2) Budding : A growth on the body as a bud grows to form indentical copy of perent. Ex : Yeast.
3) SPORES formation : spores are produced in SPORANGIUM.
Ex : Rhizopus, mucor, bacteria, ferms and mosses.
4) Regeneration : Ability of organisms to give rise to new individual organisms.
Ex : Hydra, flatwrom, tapewrom.
5) Fragmentation : New individual growth from a separate piece of parent organisms.
Ex : flatworms, moulds, lichens, spirogyra.
6) vegetative propagation :
a) Natural propagation :
i) leaves : Eg : Bryophyllum
ii) Stems:
Eg : Stolon - Vallisneria, Strawberry
Bulbs - Onion
Corms - Colacasia
Tuber - Potato
b) Artificial propagation :
i) Layering : Eg : Nerium, GUAVA, orange, rose.
ii) cutting : Eg : Rose, Hibiscus, sugarcane.
iii) Grafting: Eg : Sapota, Guava, MANGO.
