Alyssa is observing two cells, X and Y. Each cell is from either a plant or an animal. She records some of her observations in a chart.

Cell Observations

Cell X

Cell Y

has a cell wall

round shape

shaped like a rectangle

has a large nucleus

has several organelles

has ribosomes

Which additional observation will Alyssa most likely make?

1.Cell X has a cell membrane, and Cell Y does not.
2.Cell Y has a cell membrane, and Cell X does not.
3.Cell Y has chloroplasts, and Cell X does not.
4.Cell X has chloroplasts, and Cell Y does not.

1 answer

To determine which of the statements Alyssa most likely would make, let's analyze the observations she recorded about cells X and Y:

  1. Cell X has a cell wall and is shaped like a rectangle. These characteristics suggest that Cell X is likely a plant cell, as plant cells typically have a cell wall and can have a rectangular shape.

  2. Cell Y is described as having a round shape, a large nucleus, and several organelles, including ribosomes. These features are more indicative of an animal cell.

Given that:

  • Plant cells (like Cell X) typically have a cell wall and chloroplasts.
  • Animal cells (like Cell Y) do not have a cell wall and do not have chloroplasts.

Based on this information, we can evaluate the options:

  1. Cell X has a cell membrane, and Cell Y does not. - This statement is incorrect. Both cell types have a cell membrane.

  2. Cell Y has a cell membrane, and Cell X does not. - This statement is also incorrect. Both cell types have a cell membrane.

  3. Cell Y has chloroplasts, and Cell X does not. - This statement is incorrect. Chloroplasts are present in plant cells (likely Cell X, which is a plant cell) but not in animal cells (like Cell Y).

  4. Cell X has chloroplasts, and Cell Y does not. - This statement is correct. Since Cell X is likely a plant cell, it would have chloroplasts, whereas Cell Y, being an animal cell, would not have chloroplasts.

Therefore, the additional observation Alyssa is most likely to make is:

4. Cell X has chloroplasts, and Cell Y does not.
