Question

osmosis jones worksheet

1. what type of cell is jones?

what is the \goowy, white membranous\ feature that he says is surrounding him?

1. notice that all of the cars in frank run on little moving feet. to what system of the cell do these projections belong?
2. when jones moves through a wall in his attempt to catch the virus that escaped in the patrol car, he passes through a crack to get to the other side. what kind of membrane would this wall be considered if it only lets certain things (like jones) through?
3. when thrax burns a cell, you see structures floating away that look like ball-and-stick models that you may use in chemistry class. what do these structures represent and why are they seen when the cells burn up?
4. what would be the eventual effect on his cells if frank continues to eat \more sodium\ without drinking some water? why?

bonus: what trace element does he really need to avoid muscle cramps?

1. what organelle are the vehicles traveling on?

what organelle would the vehicles be?

1. what are the beads that thrax has on his chain?
2. what might jones look like if drix hadnt \saved his cytoplasm\?

Explanation:

1. Jones is a white blood cell; the gooey white membranous structure is the cell membrane (plasma membrane) surrounding his cell.
2. The moving feet-like projections are cilia/flagella, part of the cell's cytoskeleton/motility system.
3. A membrane that only allows certain substances through is a selectively permeable (semipermeable) membrane.
4. The ball-and-stick structures are organic molecules (like proteins, lipids, or carbohydrates); they float away because the cell's structure breaks down when burned, releasing its internal components.
5. High sodium intake without water would create a hypertonic environment outside Frank's cells. Water would leave the cells via osmosis, causing them to shrink and function improperly, leading to dehydration-related cell damage.
6. Vehicles travel on the cytoskeleton (cell's internal transport network); the vehicles represent motor proteins or vesicles that move materials within the cell.
7. Thrax's chain beads are DNA nucleotides (or segments of DNA), representing his ability to damage genetic material.
8. If Drix hadn't saved his cytoplasm, Jones's cell would lose its internal fluid and structural support, causing it to shrink, malfunction, and likely die.

Bonus: The trace element needed to avoid muscle cramps is potassium (K).

Answer:

1. - Jones is a white blood cell.

• The structure is the cell (plasma) membrane.

1. They belong to the cytoskeleton (cilia/flagella) system.
2. Selectively permeable (semipermeable) membrane.
3. - The structures are organic molecules (proteins, lipids, carbohydrates).

• They are released because the cell's internal structure breaks down when destroyed.

1. Frank's cells would shrink and malfunction. This happens because high sodium creates a hypertonic environment, so water leaves the cells via osmosis.
2. - Vehicles travel on the cytoskeleton.

• The vehicles are vesicles/motor proteins.

1. The beads are DNA nucleotides/segments of DNA.
2. Jones's cell would shrink, lose function, and likely die.

Bonus: Potassium (K)
