Reproduction
De?nition: The biological 
process by which organisms 
give rise to o?spring.
Importance: Ensures 
the continuation of species.
Asexual 
Reproduction
De?nition: A mode of 
reproduction involving 
only one parent.
Types of 
Asexual 
Reproduction
Fission
Unicellular organisms 
split into two 
or more individuals.
Example: Binary 
?ssion in 
Amoeba.
Fragmentation
Organisms split i
nto fragments, 
each growing into 
a new individual.
Example: Spirogyra.
Regeneration
Some organisms 
can grow entire 
individuals from 
parts of their body.
Example: Planaria, Hydra.
Budding
New individual 
grows from a bud 
due to repeated 
cell division.
Example: Hydra.
Vegetative 
Propagation
New plants grow 
from vegetative 
parts like stems, 
roots, or leaves.
Example: Bryophyllum.
Spore 
Formation
Spores are produced 
to create new individuals 
under favorable conditions.
Example: Rhizopus 
(bread mold).
Sexual 
Reproduction
De?nition: Involves two
 parents contributing 
genetic material to 
produce o?spring.
Importance of 
Sexual 
Reproduction
Generates genetic 
variation, which 
is important for 
evolution and 
species survival.
Process in 
Plants
Flower Structure: 
Contains reproductive 
organs like 
stamens and pistil.
Pollination: Transfer
 of pollen from 
anther to stigma.
Fertilization: Fusion
of male and female
gametes, resulting
 in a zygote.
Human 
Reproduction
Male Reproductive
System
Testes 
produce 
sperm.
Seminal vesicles 
and prostate gland 
provide ?uid for 
sperm transport.
Female 
Reproductive 
System
Ovaries 
produce 
eggs.
Uterus prepares 
for embryo 
implantation.
Fertilization
Sperm meets egg
in the fallopian tube, 
resulting in embryo 
development.
Menstruation
If no fertilization
occurs, 
the uterine lining 
sheds as menstrual blood.
Variation in 
Reproduction
Importance
 of Variation
Leads to adaptation 
and survival in 
changing environments.
