Reproduction
What and Why
The
process by which living organisms are able to produce more of their kind
It is
not essential for the individual
However it is
essential for the survival of the species
DNA Copying
This mechanism is
involved in sexual reproduction
DNA-
Macromolecules that are the cellular components of the hereditary transmission
DNA is
present on chromosomes
which are
located in the nucleus of the cell
DNA contains the info on how to make proteins
These
proteins form enzymes
to
control the body's chemical reactions
These
chemical reactions control the body's metabolism
to
produce specific characters
For transmission of characters,
DNA makes copies for the newly formed reproductive cells
Minor errors in DNA copying bring along variations in the offspring
Types of Reproduction
Sexual
Involves fusion of gametes
(Fertilization)
Comparatively
slower
Has
more chances of variation
(Genetically unidentical)
Needs 2 parents
Asexual
Doesn't involve fertilization
Comparatively
faster
Offspring are genetically identical
Individuals are produced from 1 parent
