The production of offspring

cell
Structures found in the nucleus of our cells
that determine our physical characteristics
(traits). They have the genetic information(DNA)
Chromosomes need to be
passed onto the offspring. They
are the “instructions” for the cell.

Do the cells in our body undergo
asexual reproduction?
Yes
When do the cells of
our body undergo
Asexual Reproduction?
Growth
Repair
Some organisms are capable of
Regeneration
The ability of
organisms to grow
back limbs if they are
cut off.
Types of Asexual Reproduction:
Fission: The splitting
of a one-celled
organism into 2 equal
halves.
Types of Asexual Reproduction:
Budding: a new cell is formed from a
tiny bud on the parent cell
What is Sexual Reproduction?
It involves the joining of two cells to
begin the development of a new
individual.
These special cells are called: Sex
Cells (Gametes)
What are the names of these sex cells?

Characteristics of Sexual Reproduction:
1) Is the creation of a new individual from
2 parents.
2) Offspring are not genetically identical

We get half our genetic information
from mom and half our genetic
information from dad
