The ovum is the scientific word for the egg cell and this is a gamete. This is thefemale’s reproductive cell that is located within the female’s reproductive system. It is
also a large size for two reasons, due to the storage of nutrients and also the ovum
contains a majority of a all organelles, DNA, and nutrients that are required for
zygote growth.
The ovum is inadequate of actively moving as it is static. During fertilization, when
the sperm cell meets the ovum, it will become a diploid cell and create a zygote. This
will gradually create a new organism.
The ovum has a nucleus, cytoplasm and cellular membrane. Located within the
nucleus is half of the genetic material, also known as the chromosomes. There are a
total of 46 chromosomes, 23 in the ovum and 23 in the spermatozoa.
The cytoplasm is essential for storing all foods and nutrients. The ovum has a large
volume of cytoplasm as it contains mitochondria that produce the ATP required for
mitosis that comes after fertilization.
