2.  doubling of cellular components> strictly controlled and monitored  nuclear mass is responsible for this process  in the nucleus there are chromosomes REPRODUCTION

3.  chromosomes in the nucleus duplicate two copies of all information are prepared  nucleus divides into two  the number of organelles doubles  both new daughter cells receive half the material of the parent cell REPRODUCTION

4.  daughter cells are identical  they are similar to the maternal cell  they are usually smaller  repeated cell division > by the growth of an individual REPRODUCTION

5. Simplified drawing of cell division: 1)Cell got bigger and can divide. 2)All parts of the cell including the content of the nucleus – hereditary information – double. 3) Nuclei and doubled cell parts divide spaciously. On each end of the cell there is one nucleus and about a half of cell parts 4) In the middle a new membrane arises, which separates both the parts from each other 5) Two new almost identical daughter cells star a new life. When they grow up to the correct size, they can also separate.

6. DIVISION OF BACTERIA REPRODUCTION

7.  ways of reproduction:  asexual  sexual  asexual reproduction:  new cells are formed from one cell  both parents are never needed  bacteria  plants  fungi  protozoa REPRODUCTION

9.  sexual reproduction:  new individual grows by dividing cells  at the beginning there are two different sex cells  sex cells = gametes  by fusion of gametes a zygote is formed REPRODUCTION
