Larger cell places demands on DNA that it cannot fulfill Ex: Large town; small library
Larger cell is unable to keep up with the intake of nutrients and the release of waste products Ex: Two way street for a busy town cause traffic
build up if the street is not enlarged

Cell cycle is how the cell grows, prepares for division, divides into two new daughter cells and then they each repeat the cycle again
What happens in phase G1?Cell has a growth spurt and increases in size while synthesizing new proteins and organelles
What happens in phase S?Replication of genetic material
What happens in phase G2? Organelles and molecules needed for cell division are
made
What happens in the M Phase?Mitosis (cell division) takes place. Two identical cells with the same genetic information as parent cell are produced

How is mitosis different in plant cells than in animal cells?
There are 2 differences!!

Contact Inhibition: Cells normally stop multiplying when they come in contact with other cells. This is mediated by cell cycle genes. Cells with mutated cell cycle genes continue to multiply, even when other cells are in close contact.
