Cell Division Flashcards
1
Q
CELL DIVISION
A
Each species will have a constant number of chromosomes which make up the genetic constitution of a living thing
The number will be even the majority of the time
The number of full set is called diploid number
2
Q
MITOSIS
A
2n———2n&2n = equational division
Equational division takes part within the whole organism apart from reproductive area (vegetable cell)
3
Q
MEIOSIS
A
2n———1n&1n = reductional division
Reproductive division
Equal distribution of split chromosome pairs in each daughter cell
Cells neede to be halved because cells are reproductive, if cells are not halved there will be two sets of chromosomes

Pterido Gymno Angio (2n) dominant phase
