cell devision/ reproduction

Question 1

how many daughter cells does mitosis form

Answer 1

2

Question 2

how many daughter cells does meiosis form

Answer 2

4

Question 3

How many chromosomes in a human diploid cell

Answer 3

46 individual chromosomes (23 pairs)

Question 4

How many chromosomes in a human haploid cell

Answer 4

23

Question 5

what’s the process of meiosis

Answer 5

cell makes copies of chromosomes(x2 genetic info)

chromosomes line up at centre of cell

LEFT AND RIGHT IS RANDOM

1st division (dna in each cell diff) and contain 46 chromosomes

chromosomes line up at centre of cells

two arms of each chromosome pulled apart

4 daughter cells formed

all are haploid (23 chromosomes)

Question 6

what’s the process of mitosis

Answer 6

all 46 chromosomes replicate

cell grows cuz increased number of organelles

chromosomes line up at centre of cell

fibres from either side of cell attach to respected half of each chromosome

fibres pull arms of chromosomes to opposite side of the cell (poles)

division takes place (membrane and cytoplasm pull apart)

2 identical daughter cells which are diploids

Question 7

which type of cell division forms gametes (sex cells) (haploids)

Answer 7

Meiosis

Question 8

which type of division forms body cells (diploids)

Answer 8

mitosis
