requirement of only one living being requirement of male and

REPRODUCTION
It is a method by which offsprings are produced by the living beings
. Reproduction is not a necessary instinct for survival of a living being

&
Green algae

I
Red algae mode of reproduction: Fragmentation

fully develop that later develops

P Develops buds to form

I
main method of
reproduction in hydra

reproduction

.
e) REGENERATION
It occurs in simple multicellular organisms like planaria and hydra, rhizopus

"
Phylum: Platyhelminthes
Eg: Tapeworms, flatworms
They are free living

f) VEGETATIVE PROPAGATION

cutting of parent plants

-

organisms repairs or regenerates

the missing part of the body and
forms a complete organism again

It is a type of reproduction where new plants grow from a fragment or

Buds develop that is
not completely
developed
 eg: in a barren land when it rains,
grass grows as stems are present
on the ground

TYPES

i) CUTTING: a part of plant (stem or leaf)

is cut and planted into soil
eg: rose plant, money plant, sugarcane plant,
-> Why is vegetative propagation done? banana plant
I
To save time
I
To get varieties of plants of same ii) LAYERING: the stem of the plant is bent
All
↑
or different type to the ground and covered with soil
eg: Lemon, strawberry

iii) GRAFTING: cutting from some other

plant attached to the stem of a plant and
planted to soil
eg: Rose plant
 g) TISSUE CULTURE
Scientific artificial vegetative propagation is known as tissue culture

:
Tissue from different parts of plant are cultured in chemicals in laboratory to
develop into a new plant

used in ornamental plants

eg: Snake plant
Cost of selling such plant
is very high

h) SPORE FORMATION
It occurs in simple multicellular organisms like rhizopus

Bob and stick

like structures that
releases spores and
these spores further
reproduces to rhizopus

IVF (In vitro fertilisation)

IVF is a type of fertility treatment where eggs are combined with the sperm outside the body in a lab. The embryos
are then inserted into women’s vagina through the cervix up to the womb

Methods of Sterilisation
I
Tubectomy: It is a permanent method of contraception for woman. It involves surgically blocking the fallopian tube so
that the egg released by ovary cannot reach the uterus

&
Vasectomy: It is a permanent method of contraception in male. It involves cutting the supply of sperm to the semen

-
Parthenogenesis: it is a natural form of asexual reproduction in which growth and development of an embryo occurred
directly from an egg without the need of fertilisation

Honey bees, lizard

.Parthe: Virgin
↑
Genesis: Birth
