Question Answer
What are the 4 main stages of the cell cycle ? Gap 1 , Synthesis , Gap 2 , mitosis
Why is cell size limited ? If the cell is too small it won't contain all necessary organelles and molecules . If it gets too big it'll cause surface area too small for adequate exchange of materials.
Why are your cells divided at different rates ? Divided to link to your body's needs fro cells.
Why do some cells have to be large ? The structure gives the neuron large surface area with relatively small increase in volume.
What is a chromosome ? It's a long continuous thread of DNA consists of numerous genes along with regulatory information.

How many stages does the cell cycle have ? The cell cycle has 9 stages .
What is telophase ? A complete set of identical chromosome positioned at each pole of cell.
