Questions and Answers 100%
PASS
B1 1) What is the difference in magnificaiton in light and electron
microscopes?—ANSWER-Cheap, easy to transport
B1 2) What is the difference in resolution between light and electron
microscopes?—ANSWER-less resolving power, less magnification
B1) 3) Define Magnification—ANSWER-How many times larger something
appears.
B1 4) What is a Micrograph?—ANSWER-Another word for a microscope
image.
B1 5) Define resolution—ANSWER-The ability to distinguish between two
points.
B1 6) How do you work out Total magnification?—ANSWER-Magnification =
magnification of eyepiece x magnification of objective lens.
, B1 7) How do you work out magnification of image?—ANSWER-
Magnification = size of image / size of real object
B1 11) What is the function of the Cell membrane?—ANSWER-Surrounds
the cell and controls the passage of substances into and out of the cell.
B1 12) What is the function of the Cell wall?—ANSWER-Found outside the
cell membrane in plant and bacterial cells, provides support for the cell.
B1 13) What is the function of the Chloroplast?—ANSWER-Found in plant
cells. Contain chlorophyll that absorbs light for photosynthesis.
B1 14) What is the function of the Cytoplasm?—ANSWER-Where most of the
chemical reactions take place in a cell.
B1 15) What is a Eukaryotic cell?—ANSWER-Type of cell that contains a
nucleus
B1 16)What is the function of the Mitochondria?—ANSWER-Where aerobic
respiration takes place.
B1 17)What is the function of the Nucleus?—ANSWER-Contains DNA and
controls cell activities.
B1 18)What is the Plasmid?—ANSWER-Small rings of DNA found in
bacterial cells.
B1 19)What is a Prokaryotic cell?—ANSWER-Cells without a nucleus.
B1 20)What is the function of the Ribosomes?—ANSWER-Where protein
synthesis occurs.
