What does a nucleus contain
genetic material/DNA of the cells
what does a eukaryotic cell contain
their genetic material inside the nucleus
properties of a prokaryotic cell
genetic material is not enclosed in the nucleus
examples of eukaryotes
animal cells and plant cells
example of prokaryotes
bacterial cell
what is bigger procaryotic cell or eukaryotic cell
prokaryotic
What is one order of magnitude
10x larger
law of magnitude
every order of magnitude is 10x greater than the one before
function of nucleus
to enclose genetic material
what is the cytoplasm
watery solution where chemical reactions take place
what is the job of the cell membrane
to control the molecules that leave and enter the cell
what takes place in the mitochondria
anerobic respiration
what does the chloroplast contain
chlorophyll and is the site for photosynthesis
what is the cell wall made of
cellulose
role of the vaculole  
give the plant cell its shape
what is cell specialisation
where a cell adapts for a specific function
what is wrong with a light magniscope
limited magnification and resolution
properties of electron magniscopes
greater magnification and resolution than light magniscopes
how many pairs of chromosomes are there
23
first stage of the cell cycle
DNA replicates to form 2 of each chromosome
second stage of cell cycle
mitosis takes place, nucleus divides.
final stage of cell cycle
cytoplasm and cell membrane divide, forming 2 identical cells.
when does mitosis take place
during asexual reproduction or when an organ heals/repairs itself
Where are stem cells found
bone marrow
problems with bone marrow transplant
patient has to be compatible with donor, viruses could be passed from donors body
relationship between temperature and diffusion
higher the temperature the higher the rate of diffusion
