BIOLOGY

2. the cell membrane disapears and finds a new nuclei
5. membranes begin to form around the 2 new nulei
6. a membrane bound structure that contains the cells hereditary information and controls the cells growth and reproduction.
7. an exact sequence of events leads to the creation of new cells
10. doughnut like shape with a depression in the centre provides large surface area to carry oxygen
12. the points where the 2 copies of dna split apart
13. the cell grows to nearly twwice its size. the number or organelles increases. the dna in the nucleus duplicates
14. leinvolved;veins, artireis, tissues, muscle,oapillaries
15. thin, flat, and layeres cells form a gap free barrier to keep out potential invaders and keep in moisture

1. the cell membrane begins to disappear
3. some have a branching pattern that increases muscle strength
4. long thread like branches enable the cells to recieve and transmit signals
8. the second phase of mitosis
9. framework of hard materials which contains minerals that provide strength and support, hold the cells together
11. the elongated cell pinches apart at the centre dividing the cytoplasm into 2 parts
