Gametophyte
The cells from the male and female that combine to form a zygote are called gametes. The main job of the gametophyte is gamete production. Gametes are haploid reproductive cells. Gametes are produced in the sex organs on the haploid gametophyte by mitosis or cellular division without reduction of chromosomes sets. There are two sex organs; archegonium<span> which is found in the female sex organ producing egg cell and </span>antheridium<span> which is found in the male sex organ producing sperm cells.</span>
<span>In table or Excel, it's merging or combining.
In biology, cells generally don't combine, they split (mother cells splits into two daughter cells)</span>
<em>DNA</em><em> </em>is what carries the genetic code for living organisms it contained in the nucleus of cells.
Hope that helps :)
