Cell Continuity
Cell continuity is the ability of cells to divide and survive from
one generation to the next.

Produce materials it will need
Grows larger
Reproduces to form a new cell

When dividing = Chromatin forms a numbers of clearly
distinguishable Chromosomes
distinguishable Chromosomes
Chromosomes are in pairs in diploid cell, called homologous pairs.
Homologous chromosomes are pairs of chromosomes that posses the
same genes, in the same positions.
Homologous chromosomes are pairs of chromosomes that posses the
same genes, in the same positions.
Diploid is symbolised as ‘2n’ and total no. of chromosomes in cell
is given as 2n=46 in humans
In diploid cells, 1 chromosome from the homologous pair comes from
the mother and the other comes from the father
