This document discusses asexual reproduction in biology. It defines asexual reproduction as reproduction that involves a single parent and produces offspring with identical genes to the parent through mitosis. The document lists and describes several types of asexual reproduction: fission, budding, spore formation, fragmentation, regeneration, and vegetative propagation. Examples are provided for each type of asexual reproduction.
2. INTRODUCTION
Reproduction is the process by which organisms
produce young ones of their own kind. There are two
types of reproduction:
1.) Asexual Reproduction
2.) Sexual Reproduction
Here we are going to deal with Asexual reproduction
3. ASEXUAL REPRODUCTION
Asexual reproduction is a type of reproduction in
which offspring are produced from a single parent
by mitosis and inherit the genes of that parent only.
It does not involve fusion of gametes and almost
never changes the number of chromosomes.
5. FISSION
A unicellular organism may divide
into two identical (Binary Fission
– Amoeba) or more (Multiple
Fission – Plasmodium) identical
daughter organisms under
favourable and unfavourable
conditions respectively.
6. BUDDING
Budding is a type of asexual
reproduction in which a new
organism develops from an
outgrowth or a bud due to cell
division at one particular site.
Ex:-Hydra
7. SPORE FORMATION
Spore formation is a method of
asexual reproduction which is
found in non flowering plants. In
this method of reproduction ,
the parent plant produces
hundreds of tiny spores which
can grow into new plants.
Ex:-Rhizopus
8. FRAGMENTATION
The body of a multicellular
organism break into two or
more fragments and each one
grows into a new individual.
Ex:-Spirogyra
9. REGENERATION
The process of getting back full
organism from the cut parts of
an organism is called
regeneration.
Ex:-Planaria
