Match the process with the correct phase of the cell cycle (G1, S, G2, M). If the process occurs in M phase indicate subphase (ex. telophase). A) ___________________ The bipolar spindle forms from microtubules. B) ___________________ The nucleus breaks down. C) ___________________ Mitochondria are duplicated. D) ___________________Sister chromatids are formed.
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:
Match the process with the correct phase of the cell cycle (G1, S, G2, M). If the process occurs in M phase indicate subphase (ex. telophase).
A) ___________________ The bipolar spindle forms from microtubules.
B) ___________________ The nucleus breaks down.
C) ___________________ Mitochondria are duplicated.
D) ___________________Sister chromatids are formed.
E) ___________________Extra cell membrane is synthesized by the smooth ER.
F) ___________________DNA is compacted into chromatin.
