Questions and Answers Graded A+
Magnification = image size / size of real object - Correct answer-What is the
equation for magnification?
Light microscope, transmission electron microscopes, scanning electron
microscopes - Correct answer-What are the names of the 3 microscopes?
Give 2D images with very high magnification and resolution - Correct answer-
Transmission electron microscopes...
Give 3D images with lower magnification - Correct answer-Scanning electron
microscopes...
Cell membrane, nucleus, cytoplasm, mitochondria, ribosomes - Correct answer-
Animal cells contain...
Chloroplasts, cell wall and a permanent vacuole - Correct answer-What do plant
cells contain, not animal cells?

, Chlorophyll absorbs light so the plant can make food by photosynthesis - Correct
answer-What do chloroplasts contain and what does it do?
They increase the surface area available for water to move into the cell.
They have a large permanent vacuole that speeds up the process of osmosis from
the soil.
They have many mitochondria that transfer the energy needed for active transport
of mineral ions. - Correct answer-Give 3 adaptions of the root hair cells
Xylem cells are alive when first formed but a chemical called lignin builds up in
spirals in the cell walls. The cells die and form hollow tubes that transfer water and
mineral ions.
The spirals of lignin in the xylem cells make them very strong to help them
withstand pressure. - Correct answer-Give 2 adaptions of xylem cells
Lots of dendrites to make connections to other nerve cells.
An axon that carries nerve impulses from one place to another.
Synapses (nerve endings) are adapted to pass impulses to another cell using
transmitter chemicals; they also have lots of mitochondria to make the transmitter
chemicals. - Correct answer-Give 3 adaptions of nerve cells
A long tail moves to help the sperm travel.
