CELL DIVISION IN AN ANIMAL CELL
CELL DIVISION IN AN ANIMAL CELL
nucleus divides first and the two daughter nuclei separate then the cytoplasm divides to form two new cells called daughter cells this is called BINARY FISSION
form of reproduction (animal cells) results in growth (human cells) increases its number of cells (multicellular organisms)
thread like structures found in every nucleus of every living cell each chromosome carries information which is necessary for the development of the cell
every species has a fixed number of chromosomes in each cell
human chromosome number is 46
type of cell division
nucleus divides so the new cells have the same number of chromosomes as their parent cells
ne
new cells have the exact same genetic info as parent cells
the chromosomes are not seen in the nucleus the chromosomes double to make two chromatids the chromosomes line up at the middle of the cell the chromatids separate and move to opposite ends of the cell the chromosomes form a nucleus in each daughter cell mitosis is complete
mitosis must occur before cell division to ensure the new cells produced have the correct chromosome number (which ensures they function properly)
