You are looking at a spread of cells in some unknown stage of cell division, and you discover that there are seven chromosomes (3 metacentric, 3 telocentric, and 1 acrocentric) visible in each dividing cell. What type of nuclear division have you identified, and what conclusions can be drawn about the number of chromosomes that make-up the species?
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

Cells are the biological, structural and functional unit of an organism. Cell has a nucleus. Nucleus is a membrane bound organelle that contains chromosomes. Chromosome has DNA which contains genetic information.
