$100 Question: Diffusion What is diffusion?
$100 Answer: Diffusion The movement of molecules from areas of higher concentration to areas of lower concentration.
$200 Question: Diffusion Does diffusion require extra energy?
$200 Answer: Diffusion No. It occurs with no added energy.
$300 Question: Diffusion Why are cells small?
$300 Answer: Diffusion Diffusion is a slow process. Diffusion into larger cells would take too long to transport materials in and out of the cell.
$400 Question: Diffusion Heat is simply molecules moving quickly. Would increasing temperature increase or decrease the rate of diffusion?
$400 Answer: Diffusion Increasing temperature would INCREASE the rate of diffusion. Molecules move faster when heated!
$500 Question: Diffusion Which cell would experience the higher rate of diffusion of material into it: a chicken egg or an ostrich egg?Which would have the larger surface area to volume ratio? CHICKEN EGG OSTRICH EGG
$500 Answer: Diffusion Diffusion would occur faster into the chicken egg because of its smaller size. It would have the larger surface area to volume ratio.
$100 Question: Osmosis What is osmosis?
$100 Answer: Osmosis The diffusion of water across a membrane.
$200 Question: Osmosis Why shouldn’t you drink salt water?
$200 Answer: Osmosis The salt dehydrates your cells by pulling water from them.
$300 Question: Osmosis Which of the following is better for animal cells: being in a hypotonic solution; being in a hypertonic solution; or being in an isotonic solution?
$300 Answer: Osmosis Being in an isotonic solution. Both hypotonic and hypertonic solutions lead to cell death for animal cells.
$400 Question: Osmosis What would happen if you put eggs laid by a salamander (a frog relative) in fresh water into salt water? Is this a hypotonic, hypertonic, or isotonic solution?
$400 Answer: Osmosis The water in the eggs (which are cells) would leave the eggs. The eggs would shrivel and die. This is a hypertonic situation.
$500 Question: Osmosis Compare the effect of putting an animal cell and a plant cell into a hypotonic solution.
$500 Answer: Osmosis Water moves into both cells. The plant cell will swell, but won’t burst because of the plant cell wall. The animal cell will burst, because it does not have a cell wall.
$100 Question: Organelles Which organelle is responsible for housing the DNA in eukaryotic cells?
$100 Answer: Organelles The nucleus.
$200 Question: Organelles What parts are found in ALL cells? List at least THREE!
$200 Answer: Organelles Cytoplasm, ribosomes, DNA, cell membrane.
$300 Question: Organelles If the cell needs to export a protein produced in the rough endoplasmic reticulum, what other organelles could that protein travel through? Your answer should trace the path of the protein from the ER out of the cell.
$300 Answer: Organelles The protein would likely travel through the rough ER to the Golgi. It would be packaged in a vesicle and sent through the cell membrane.
$400 Question: Organelles A cell converts energy from food it eats into energy that’s usable by the cell using an organelle. What kind of cell is this likely to be? How do you know?
$400 Answer: Organelles The cell could be any eukaryotic heterotroph Including an animal cell, fungal cell or “protist” cell. It’s a eukaryote because it has membrane- bound organelles (in this case, mitochondria). It’s a heterotroph because it obtains food from outside sources.
$500 Question: Organelles Not all plant cells have chloroplasts, yet no plant cells have to obtain food the way animals do. Explain based on your knowledge of cells and organelles.
$500 Answer: Organelles Plant cells in leaves (and to some extent in stems, tendrils, etc.) have chloroplasts that can take sunlight energy and convert it to food energy. That sugar is transported to other parts of the plant, such as the bulb of an onion, and stored or used.
$100 Question: Membranes Define “selective permeability.”
$100 Answer: Membranes Cells are choosy about what enters into and exits from them.
$200 Question: Membranes What structures in the cell membrane are responsible for it being selectively permeable?
$200 Answer: Membranes Phospholipids, proteins and carbohydrates
$300 Question: Membranes Draw a phospholipid. Which part is attracted to water? Which part is repelled by water?
$300 Answer: Membranes O The phosphate head is attracted to water. The fatty acid tails are repelled by it.
$400 Question: Membranes A colander (metal or plastic bowl with a lot of holes in it used to drain pasta) will let water out but not food. Is this selective permeability? Why or why not?
$400 Answer: Membranes Yes, this is selective permeability, because the colander is choosing what passes through it.
$500 Question: Membranes Mitochondria evolved from bacteria that moved into eukaryotic cells and stayed. What structures do you think are necessary to transport materials into and out of mitochondria? WHY?
$500 Answer: Membranes Mitochondria are surrounded by a phospholipid bilayer with proteins in it for active transport and facilitated diffusion. Since mitochondria evolved from bacteria, they have similar structures to those found in prokaryotic cell membranes. Those structures are homologous to those found in cell membranes.
$100 Question: Transport Does passive transport require energy?
$100 Answer: Transport No. It doesn’t need any additional energy.
$200 Question: Transport Name three types of active transport.
$200 Answer: Transport Ion pumps; exocytosis; endocytosis.
$300 Question: Transport Why can diffusion be classified as an example of passive transport?
$300 Answer: Transport Diffusion is classified as passive transport because it requires no additional energy.
$400 Question: Transport Endocytosis requires energy to bring food particles and liquids into the cell. This is an example of: Passive Transport Osmosis Diffusion Active Transport
$400 Answer: Transport D. Active Transport.
$500 Question: Transport Compare active transport and facilitated diffusion.
