cell x\tcell y
has a cell wall\tround shape
shaped like a rectangle\thas a large nucleus

has ribosomes
which additional observation will alyssa most likely make?
cell x has a cell membrane, and cell y does not.
cell y has a cell membrane, and cell x does not.
cell y has chloroplasts, and cell x does not.
cell x has chloroplasts, and cell y does not.

Explanation:

Plant cells typically have a cell wall, are often rectangular - shaped, and may have chloroplasts. Animal cells are usually round - shaped and lack a cell wall and chloroplasts. Since Cell X has a cell wall and is rectangular (characteristics of plant cells), it is likely a plant cell and may have chloroplasts. Cell Y has characteristics more typical of an animal cell and would not have chloroplasts.

Answer:

Cell X has chloroplasts, and Cell Y does not.
