Cell Society Diffusion Dilemma and Water Shortage Quiz

When a cell society becomes crowded with people, most people would want to move outside the cell because it would provide more space and alleviate the feeling of being crowded. Moving outside the cell would also allow individuals to have access to fresh air and potentially find more resources or opportunities.

Active transport requires energy in order to happen. Passive diffusion and osmosis, on the other hand, do not require energy. Active transport is a process in which molecules or ions move across a cell membrane against their concentration gradient, from an area of lower concentration to an area of higher concentration. This movement is facilitated by specific transport proteins called pumps, which require energy in the form of ATP to actively transport substances across the membrane.

Active transport is the correct answer because it refers to the process in which solutes or particles move from an area of low concentration to an area of high concentration. This process requires the expenditure of energy by the cell or organism to transport molecules against the concentration gradient. Unlike passive diffusion, which occurs without the need for energy, active transport is a vital mechanism for maintaining homeostasis and ensuring the proper functioning of cells. Osmosis, on the other hand, refers specifically to the movement of water molecules across a semi-permeable membrane.

Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. It is a passive process that does not require energy. In osmosis, water molecules move in order to equalize the concentration of solute on both sides of the membrane. This process is important for maintaining the balance of water and solutes in cells and tissues.

The given answer is "Hypotonic" because the question mentions "Using this situation" which implies that there is a situation described in the previous context. However, since the context is not provided, it is not possible to determine the specific reason why the outside is hypotonic compared to the cell.

The given answer states that the cell would stay the same. This implies that there would be no change in the size or volume of the cell. It suggests that the situation described does not have any effect on the cell's size or shape.

The outside solution is isotonic compared to the cell because it has the same concentration of solutes as the cell. In an isotonic solution, there is no net movement of water across the cell membrane, resulting in a stable cell volume.

When the question mentions "using this situation," it implies that there is a specific situation being referred to, although it is not explicitly mentioned. In general, water moves inside the cell when there is a higher concentration of solutes (such as salts or sugars) inside the cell compared to outside. This creates a concentration gradient, causing water to move from an area of lower solute concentration (outside the cell) to an area of higher solute concentration (inside the cell) through a process called osmosis. Therefore, the correct answer is "Inside the cell."

Osmosis is the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this situation, water will move both inside and outside the cell through osmosis. If the solute concentration is higher inside the cell compared to the surrounding environment, water will move from outside the cell to inside, causing the cell to swell. Conversely, if the solute concentration is higher outside the cell, water will move from inside the cell to outside, causing the cell to shrink. Therefore, osmosis can occur in both directions depending on the relative solute concentrations.

Since the starfish cells have lots of salt and the freshwater has a low concentration of salt, that means the freshwater is hypotonic to the starfish cells. Hypo= Low. Whenever cells are in hypotonic solutions, water goes into the cell and makes the cell swell.
