She's so cute she's like a mini human. I can't believe you carried that in your belly for nine months.
Don't be silly! She wasn't this big all the time she had to develop inside my belly.
Wait what!? This baby completely formed in my moms belly. This is fascinating I'm going to ask the doctor about it.
Hi doctor! I wanted to ask you how do babies develop inside a mothers tummy, and how they stay alive and grow once their born.
I can help you with that! Pay close attention!
The first thing that has to happen for a baby to be created is fertilization. Here a sperm will fuse with an egg and result in the creation of a zygote. The first cell of the organism.
That's so cool! But how are more cells made after? Do more eggs need to be fertilized for more cells to be created?
Nope! The zygote can divide to replicate itself with the same genetic material through a process called cell division. One of the ways cell division happens in through mitosis. Before we go any further let me explain cell division to you!
