10TH GRADE BIOLOGY FINAL EXAM
QUESTIONS AND ANSWERS RATED A+
Light Microscope - ANSWER-1000-2000 times magnification
Electron Microscope - ANSWER-2 million times magnification
Prokaryote - ANSWER-A unicellular organism that lacks a nucleus and membrane
bound organelles. PRO = BEFORE NUCLEUS
Eukaryote - ANSWER-A cell that contains a nucleus and membrane bound
organelles. EU = TRUE NUCLEUS
Principles of Cell Theory - ANSWER-Cells are the basic units of live,
all living things are made of cells, and
all cells come from existing cells.
Hypertonic - ANSWER-Having a higher concentration of solute than another
solution. CELLS SHRINK
Hypotonic - ANSWER-A solution that has a lower concentration of solutes than
another. CELLS BURST
Isotonic - ANSWER-A solution whose solute concentration is equal to the solute
concentration of another solution.
ISO = SAME
Diffusion vs Osmosis - ANSWER-Osmosis = low conc. to high conc.,
always water across a selectively permeable membrane.
Diffusion = high conc. to low conc., can occur in any substance! Always equals out!
Producer / Autotroph - ANSWER-An organism that makes its own food.
Consumer / Heterotroph - ANSWER-An organism that obtains energy by feeding on
other organisms
Nucleus - ANSWER-Control center of the cell
Contains DNA
Ribosome - ANSWER-Cytoplasmic organelles at which PROTEINS are synthesized.
