MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The ovum nucleus and sperm nucleus combine to form a ____, which then begins dividing by mitosis to form a new organism.
A
ovum
B
zygote
C
primordial
D
ovarian follocles
Explanation: 

Detailed explanation-1: -Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote.

Detailed explanation-2: -Within the ovum, the nuclei of the sperm and ovum fuse, forming a diploid nucleus. This fertilized egg cell is called a zygote.

Detailed explanation-3: -Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm are haploid, which means they each contain one set of chromosomes; upon fertilization, they will combine their genetic material to form a zygote that is diploid, having two sets of chromosomes.

Detailed explanation-4: -There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

Detailed explanation-5: -Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg). The development of a new progeny organism is then initiated by the fusion of these gametes at fertilization.
