Veins and arteries are organs because they are made up of more then one tissues but capillaries aren't.

The genes are switched on for the job it needs and the rest are off as their are not needed for this cells job.

The develop to do the job because the genes are copied during mitotic division.

Cell differentiation = cells becomes specialised in structure to suit the role they perform.

Interphase divided into 3 parts = first growth (protein producted), synthesis (DNA is replicated) and second (cont) http://tl.gd/1k8jl7

Repair = repair and damage cells back to their original structure so they can preform the same function as before.

Differentiation = cells do the same jobs for effeiciency and same function and have same structure.

Growth = two haploid cells fuse to form a diploid cell. Reproduction.

Telophase = nuclear envelope forms and things go back to normal. Spindles go, chromatids become invisible and nucleolus reforms.
1 Jun 2010
Anaphase = chromotids seperate and move to the opposite sides of the poles by the spindle fibres.
1 Jun 2010
Metaphase = chromosomes arrange themselves at the equator of the cell and spindle fibres forms.
1 Jun 2010
Prophase = chromosomes become visible and nuclear envelope disappears and nucleolous disappears.
1 Jun 2010
Interphase = most cell activity happens, protein synthesis, DNA replicates.

Process of mitosis = interphase, prophase, metaphase, anaphase, telophase.
