1. Magnification Image size/real size
2. Resolution The ability to distinguish between two points
3. Cytoplasm A jellylike fluid inside the cell in which the or-
ganelles are suspended
4. Nucleus A part of the cell containing DNA and RNA and
responsible for growth and reproduction
5. cell membrane thin, flexible barrier around a cell; regulates what
enters and leaves the cell
6. Mitochondria where cellular respiration takes place
7. Ribosomes Makes proteins
8. What type of micro- Electron microscope
scope would be best to
look at ribosomes
9. Chloroplast found in plant and algae cells where photosynthe-
sis occurs
10. cell wall a rigid layer made of cellulose that protects the
cell
11. Vacuole A sac inside a cell that acts as a storage area
12. What is found in the vac- cell sap
uole?
13. Bacterial cells have Plasmids
small ring of DNA called

15. prokaryotic cell smaller simpler with DNA free in the cytoplasm.
divides through binary fission
16. Sperm cell adaptations Long tails, many mitochondria, acrosome, large
nucleus
17. Nerve cell adaptations Lots of dendrites (to make connections)
Axon carries nerve impulse.
Axon can be very long.
Synapse produces special transmitter chemicals.
18. Root hair adaptations High surface area, large vacuole, many mitochon-
dria
19. Xylem adaptations Very long, waterproofed with lignin, hollow
20. Phloem adaptations holes allow liquids to flow, pore through which
sucrose is pumped, small cytoplasm = more room
for central channel
