Reproduction and Growth

All living organisms reproduce. Reproduction is the process by which organisms generate new individuals of the same kind ensuring continuation of the species.

 

There are two different types of reproduction:

  1. Asexual
  2. Sexual

They both lead to the formation of new individuals, however they achieve this by different ways.


Asexual Reproduction

In this type of reproduction only one individual is needed for it to take place.  This method produces offspring that are identical to the parent.  The offspring have exactly the same genes as their parents and are thus called clones

Some examples of asexual reproduction are:

a) Amoeba

These unicellular organisms reproduce by one cell dividing into two.

 



b) Hydra

These are multicellular animal cells.  Little buds grow on the outside of the parent body and eventually break off to form separate individuals. 

 

c) Potato plant

The potato plant forms potato tubers which become detached to make new plants.
