Q1: What is the main function of the cell membrane?
A1: Controls what goes in and out of the cell.
Q2: What is the cell membrane made up of?
A1: Phospholipid bilayer and channel protein.
Q3: Which side of the phospholipid bilayer is hydrophobic, and which side is hydrophilic?
A3: Head is hydrophilic, tail is hydrophobic.
Q4: What is the three ways to transport molecules?
A4: Active transport, facilitated diffusion, simple diffusion.
Q5: What is osmosis?
A5: The movement of water molecules from an area of high water to low water potential.
TRICKY
Q1: What is active transport?
A1: The movement of molecules from an area of low to high concentration with the help of
energy and channel protein.
Q2: What is facilitated diffusion?
A2: The movement of molecules from an area of high to low concentration with the help of
channel protein.
Q3: What is simple diffusion?
A3: The movement of molecules from an area of high to low concentration through the
selectively permeable membrane.
Q4: What is a hypertonic solution?
A4: When the extracellular solution is higher.
Q5: What is an isotonic solution?
A5: When the solution inside and outside the cell are the same.
DIFFICULT
Q1: List three differences between a plant cell and an animal cell.
A1: Animal cells don’t have a cell wall, but plant cells do. Animal cells don’t have chloroplasts,
but plant cells do. Animal cells don’t have a large permanent vacuole, but plant cells do.
Q2: List three differences between a prokaryote and a eukaryote.
A2: Eukaryotes have a nucleus, but prokaryotes do. Eukaryotes have mitochondria, but
prokaryotes don’t. Prokaryotes contain free floating DNA, but eukaryotes don’t.
Q3: What does the word karyon mean?
A3: Nucleus.
Q4: What does the cholesterol do in a phospholipid bilayer?
A4: It decreases flexibility.
Q5: What is the term for the change in an animal cell when it is put into a hypertonic solution?
A5: Crenated
SUPER DIFFICULT
Q1: List the three types of prokaryotes.
A1: Coccus, spirillum, bacillus.
Q2: Do golgi apparatus exist in both plant and animal cells?
A2: Yes
Q3: What is the tail-like structure in a type of prokaryote?
A3: Flagellum
Q4: Name all organelles a typical prokaryote cell contains.
A4: Cytoplasm, free floating DNA, cell wall, ribosomes (flagellum in some cases)
Q5: What is the function of an endoplasmic reticulum?
A5: Folding of protein molecules.
