Reproduction

Cellular reproduction is the process of a stem cell making daughter cells.

We have 2 types of cellular reproduction:

We can represent like this:

      

           Mitosis

              2n

          2n    2n 

    2 daughter cells              

         

           Meiosis

               2n

           n       n               

     4 daughter cells    

Vegeative reproduction: 

It is the reproduction of a plant from a cell, a tissue or an organ of the mother plant.

Asexual: They don´t need seeds and has the sexual organs between themselves

Sexual: Needs male and female organs to reproduce.

Asexual Sexual

Genetic

Means inheritance through biology

Genetics says the characteristics you have from your parents bone (inheritance).

Genetics can find in the DNA

In the RNA we can see that they only have one elix and also that instead of thymine as well as the DNA has, Uracil has instead the DNA has 2 elixes.

The parts of DNA are nitrogenous base phosphate group and deoxyribase sugar (S carbon sugar).
Gametogenesis:
Gametogenesis is the formation of gametes through meiosis from germ cells.
