cell wall

Answer 1

Given that the cell is described as round and incapable of producing its own food, the organelle that you would assume the cell must have is the plasma membrane.

Here’s the reasoning:

• Chloroplast: This organelle is involved in photosynthesis, which is how a cell produces its own food, so a cell incapable of producing its own food would not have chloroplasts.
• Cell wall: While many cells, like those of plants, have a cell wall, it is not a characteristic of all cells, especially round (often animal) cells.
• Central vacuole: This organelle is typically found in plant cells and is involved in storage and maintaining turgor pressure, but it is not essential for all cell types, especially if the cell is round and not a plant cell.

Thus, the most essential common feature for all cells is the plasma membrane, which encases the cell and regulates what enters and exits.

Answer 2

is that correct

Answer 3

Yes, that is correct. The plasma membrane is an essential structure found in all types of cells, including both plant and animal cells. It serves as a barrier that regulates the movement of substances in and out of the cell, making it suitable for the described round, non-photosynthetic cell.

To clarify further:

• Chloroplasts are present only in photosynthetic organisms (like plants and algae) and are responsible for producing food (glucose).
• Cell walls are found in plant cells (and some bacteria and fungi) but not in animal cells, which are generally round.
• Central vacuoles are primarily found in plant cells for storage and maintaining turgor pressure but are not present in all cell types.

So, the plasma membrane is indeed the correct organelle that a round, non-food-producing cell must have.
