Are animal cells eukaryotic or prokaryotic? - (ANSWER)Eukaryotic
Are plant cells eukaryotic or prokaryotic? - (ANSWER)Eukaryotic
Are bacteria cells prokaryotic or eukaryotic? - (ANSWER)Prokaryotic
are prokaryotic cells much bigger or smaller than eukaryotic? - (ANSWER)much
smaller
Parts of a eukaryotic cell - (ANSWER)cell membrane, cytoplasm, nucleus
Parts of a prokaryotic cell - (ANSWER)cell wall
dna loop
cell membrane
cytoplasm
plasmids
give 5 sub cellular structures that are found in both animal and plant cells? -
(ANSWER)-nucleus
-cytoplasm
,2|Page
-cell membrane
-ribosomes
-mitochondria
give 3 sub cellular structures that are found in plant cells but not in animal plants?
- (ANSWER)-cell wall
-chloroplasts
-permanent vacuole
what the function of the nucleus ? - (ANSWER)contains genetic material
Function of cell membrane - (ANSWER)regulates what enters and leaves the cell
function of mitochondria - (ANSWER)cellular respiration
function of chloroplast - (ANSWER)Contains chlorophyll which absorbs light
energy for photosyntheis
cell wall function? - (ANSWER)provides support and protection
function of plasmids in bacteria cell? - (ANSWER)contains extra genetic material
that can help the bacteria cell survive

What are plant cell walls made of? - (ANSWER)cellulose
what is a plant cells permanent vacuole filled will? - (ANSWER)cell sap
give 2 differences between electron microscopes and light microscopes? -
(ANSWER)electron microscopes have a much higher magnification and a much
higher resolution than light microscopes
what formula is used to calculate magnification of an image? -
(ANSWER)magnification = imagine size /real size
give a brief method for using a light microscope to look at a prepared slide -
(ANSWER)USING A LIGHT MICROSCOPE TO LOOK AT A PREPARED SLIDE
1)put the slide on the stage
2)select the lowest power lens
3)use the coarse adjustment knob to roughly focus the slide
4)use the fine adjustment(FA)knob to clearly focus the slide
5)switch to a higher power lens to increase magnification and refocus with the FA
knob
give 3 things to remember when drawing cells observed through a light
microscope ? - (ANSWER)-use a pencil
-label the main structures
-include the magnification used
, 4|Page
what happens when cells differentiate? - (ANSWER)when cells differentiate they
develop different sub-cellular structures that make them carry out certain
functions
how are animal cells different to plant cells in their ability to differentiate? -
(ANSWER)most animal cells differentiate early in development and can't
differentiate again
many plant cells can differentiate whenever they need to
give 3 ways that a sperm cell is specialised to do its job - (ANSWER)FUNCTION:to
get DNA into egg cell
-tail for swimming
-lots of mitochondria to provide energy
-enzymes in head to digest egg cell membrane
give 2 ways that a nerve cell is specialised to do its job -
(ANSWER)FUNCTION:carries messages around the body at high speed
-fatty sheath speeds up message transport
-long so it can carry messages over a distance
how is a plant root cell specialised to do its job? - (ANSWER)FUNCTION:helps a
plant absorb water and minerals from soil.
