Exam Questions and CORRECT Answers
Cell Membrane - CORRECT ANSWER - A thin semipermeable barrier around the cell
which regulates what enters and leaves the cell
Cell Wall - CORRECT ANSWER - This structure provides support and protection for
plant cells
Chloroplasts - CORRECT ANSWER - This is used by plant cells for photosynthesis
Mitochondria - CORRECT ANSWER - It is often described as the cell's Power Plant
Nucleus - CORRECT ANSWER - The control center of the cell
Vacuole - CORRECT ANSWER - This is a large, central fluid-filled structure that
provides turgidity
RNA - CORRECT ANSWER - A single stranded nucleic acid that plays a role in protein
synthesis
Monomer: Nucleotide
- phosphate
- ribose sugar
- nitrogen containing base
DNA - CORRECT ANSWER - This holds an organism's hereditary information
Monomer: Nucleotide
- double stranded
- double helix
, - bases are connected by hydrogen bonds
Double Helix - CORRECT ANSWER - This is the structure of DNA as first published by
James Watson and Francis Crick
Ribose - CORRECT ANSWER - This is a 5-carbon sugar which is a structural component
of RNA,
Deoxyribose - CORRECT ANSWER - This is sugar found in the side chains of DNA
Isotonic - CORRECT ANSWER - When the concentration gradient of solute and solvent
are equal on both sides of the membrane
Hypertonic - CORRECT ANSWER - A solution that causes a cell to shrink because of the
high concentration of solute in the solution surrounding the cell
- more solute, less water
Hypotonic - CORRECT ANSWER - A solution that causes a cell to shrink because of
osmosis
- less solute, more water
Active Transport - CORRECT ANSWER - Process requiring energy for the movement of
particles across a cell membrane against the concentration gradient
Passive Transprt - CORRECT ANSWER - A non-energy requiring process that moves
materials across a cell membrane with the concentration gradient
Diffusion - CORRECT ANSWER - The process when particles tend to move from an area
of high to low concentration
