Combined Science Trilogy)
Cells are - correct answerwhat living things are made up of The two groups of cells -
correct answerProkaryotic and Eukaryotic Eurkaryotic cells - correct answerare
complex. They include animal and plant cells Prokaryotic cell - correct answerare
smaller and simple. Structures within cells - correct answerSubcellular structures
Nucleus' function + purpose - correct answercontains genetic material that controls
activity Cytoplasm's function + purpose - correct answerplace where chemical reaction
happens. Enzymes control the reaction Cell Membrane's function + purpose - correct
answerHold cell together and control what enter and exits Mitochondria's function +
purpose - correct answerAerobic respiration transfer energy for cell. Ribosome's
function + purpose - correct answerProtein synthesis Cell wall's function + purpose -
correct answerSupport and strengths cell Cell wall material - correct answerCellulose
Permanent vacuole function + purpose - correct answerHas cell sap Chloroplast's
function + purpose - correct answerWhere photosynthesis happens and creates food.
They contain chlorophyll Subcellular structures of a bacterial cell - correct answerCell
wall Cell membrane Cytoplasm Plasmids How do light microscopes work? - correct
answerThey use light and lenses to form an image and magnify it. What can you see
with a light microscope? - correct answerIndividual cells and nuclei What can you see
with a electron microscope? - correct answerInternal structure of mitochondria and
chloroplasts. Ribosomes and plasmids. What is the difference between electron and
light microscopes? - correct answerElectron microscopes have a higher resolution.
Magnification equation - correct answerMagnification = image size/ real size What do
you need to do in the B1 onion experiment before you put iodine? - correct answerPeel
the epidermal tissue off What do you need to do in the B1 experiment before you place
the epidermal tissue on the slide? - correct answerAdd a drop of water on the slide.
Why do you add iodine to the epidermal tissue in the B1 onion experiment? - correct
answerTo highlight object in the cell. What do you need to do in the B1 onion
experiment after you add a cover slip? - correct answerMake sure there are no air
bubbles. What do you need to do in the B1 onion experiment before you touch the
coarse adjustment knob? - correct answerPut it on the lowest powered objective What
does the coarse adjustment knob do? - correct answerMove the stage up and down.
Differentiation - correct answerWhen a cell changes to become specialised
Differentiation in animal cells - correct answerLost ability in a early stage Differentiation
in plants cells - correct answerNever lost ability Undifferentiated cells - correct
answerStem cells Sperm cell specialised features - correct answerlong tail to help swim
streamlined head to help swim mitochondria for energy Enzymes to digest through
