Multiplying cells
- advantages of being multicellur
- bigger - travel
further - get
nutrients in different
ways - fewer things
can eat and squash
you
- cell differentiation - one cell
doing doing everything -
different cells instead doing
different jobs
- specially adapted
- more complex
- speciallised
organs-
different
shapes and
behaviour
adapted
specially to
their
environment

- specialised organ systems:
- communication system
= nervous sytem
- cells with
nutrients they
need =
circulatory
sytem
- exchange of
substances =
respiratory sytem
- communication system
= nervous sytem
- mitosis = new cells for growth and repair
- cell reproduces itself by spilting - forming 2 identical offspring
- 1. DNA replicated
- 2. DNA coils into double armed chromosomes - arms
are exact copies of each other - same DNA
- 3. chromosomes line up at center
of the cell - divide as cell fibres pull
them apart - 2 arms of each
chromosome go to opposite poles
- 4. membranes form around each of the 2
different sets of chromosomes
- 5. cytoplasm divides - 2 new
cells = same genetic material as
original
