Biology EOC Review Questions and
Answers|Latest Update
Active Transport Requires energy (ATP) for large molecules. Gets molecules across the
cell through pumps and vesicles. From a low concentration to a high concentration
Vesicles Used when molecules are too large to pass through the membrane, even with
the help of a transport protein
Endocytosis Large molecules going INTO the cell
Exocytosis Large molecules going OUT of the cell
Concentration Gradient Drives diffusion; usually from a high to low concentration (down
the concentration gradient )
Nucleus Only in eukaryotic cells, command center of the cell where the DNA is keep
,Mitochondria Makes ATP, (Power house of the cell); Where Cellular Respiration occurs
Chloroplast Makes glucose for the plant; Where Photosynthesis occurs
Lysosomes Breaks down waste, food, etc.
Vacuole Where molecules, waste, etc. is stored; Bigger in Plant Cells
Ribosomes Makes protein; Where translation in protein synthesis occurs
Rough ER Transports Proteins; Has Ribosomes on the surface
Smooth ER Transports Lipids (sometimes proteins) ; Does not have Ribosomes
Golgi Apparatus UPS of the cell; Sorts and packages molecules
Cell Membrane Semi-permeable, therefore maintains homeostasis
, Cell Wall Only in Plant and Bacteria cells; supports and provides protection
Cytoplasm dissolves nutrients, allowing diffusion to occur; holds all the organelles
Hypotonic Water only entering the cell, resulting in it being Lysed/Burst
Isotonic Same amount of water entering the cell as existing, resulting in an equilibrium,
normal Cell
Hypertonic Water only exiting the cell, resulting in it being shriveled
Photosynthesis
Cellular Respiration
