EASY 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.
