Reproduction
Reproduction is the process by Which all the organism multiply in number and increase their populations.
Asexual Reproduction:
A sexual reproduction is a method of reproduction that involves only one organism. A single organism reproduce two or multiple organism on its own. This is seen in all unicellular organism some multicellular and few plants.
Fission:
Fission is an asexual reproduction that is common in most of the unicellular organism.
1. Fission results in two daughter cell. It is binary fission e.g paramecium
amoeba.
2. When fission result in many daughter cell, it is called multiple fission e.g. Plasmodium.
Budding:
Budding is a type of asexual reproduction in which a small cyst-like structure is formed
on the parent's body which gives rise to a new individual.
Bud may remain attached to the parent e.g(yeast) or may separate and become a
new individual e.g hydra.
Regeneration:
It is the process of growing back the last organ or body part by the
Organism. E.g Lizard
Fragmentation:
It is the process by which an organism gets fragmented into smaller pieces and each piece
grow into a whole new organism. E.g Planaria, Hydra.
Spore Formation:
Organism such as fungi make spores that can grow into complete new individual when dispersed from their fruiting body.
Vegetative Propagation:
It is a type of asexual reproduction seen in plants.
-> The vegetative part of the plant like leaves, stem , roots gives rise
to a new plant.
-> Vegetative propagation can artificial or natural.
-> Natural vegetative propagation happens through leaves(e.g bryophyllum), stem,(turmeric, ginger)
runners/stolon(eg. grass strawberry) bulbs (e.g. onion, lily) etc.
-> Artificial method include, cutting, grafting layering and plant tissue culture.
