Cell Basics
$100: According to cell theory, all living organisms are made of these.
Cells
$100: These structures make proteins.
Answer: Ribosomes
$100: The cell membrane is primarily made of this type of molecule.
Phospholipid
$100: The diffusion of water across a membrane is called this.
Osmosis
$100: Bacteria are this type of cell.
Prokaryotic
$200: According to cell theory, all cells come from these.
Answer: Pre-existing cells
$200: This organelle is the site of cellular respiration.
Answer: Mitochondrion / Mitochondria
$200: The cell membrane contains this many phospholipid layers.
Two
$200: Movement from high concentration to low concentration without energy is called this.
Answer: Simple diffusion
$200: This structure is found in eukaryotes but not prokaryotes.
Nucleus
$300: These cells contain a nucleus and membrane-bound organelles.
Answer: Eukaryotic cells
$300: This organelle modifies and packages proteins.
Answer: Golgi apparatus
$300: The water-fearing part of a phospholipid is called this.
Hydrophobic
$300: Transport that uses a membrane protein but does not require energy is called this.
Answer: Facilitated diffusion
$300: Bacterial cell walls contain this substance.
Peptidoglycan
$400: Plant and animal cells belong to this cell type.
Answer: Eukaryotic
$400: This organelle contains digestive enzymes that break down old cell material.
Lysosome
$400: The interior of the phospholipid bilayer is described by this term.
Hydrophobic
$400: Moving molecules against their concentration gradient requires this type of transport.
Answer: Active transport
$400: These two organelles are believed to have once been free-living bacteria.
Answer: Mitochondria and chloroplasts
$500: Cell theory says all of the following are true EXCEPT that all cells have this structure.
Answer: A rigid cell wall
$500: Rough ER primarily makes these, while smooth ER makes lipids and sugars.
Proteins
$500: These types of molecules can cross the membrane through simple diffusion most easily.
Answer: Small, uncharged molecules
$500: A cell placed in a hypertonic solution will experience net water movement in this direction.
Answer: Out of the cell
$500: This theory explains how mitochondria and chloroplasts originated from free-living prokaryotes.
Answer: Endosymbiotic theory
