All organisms are made up of cells. Some organisms are

unicellular,

or made up of just one cell. Other organisms are

multicellular,

or made up of many cells.

These

micrographs,

or magnified pictures taken with a microscope, show cells from organisms of four different species.

Cells of Homo sapiens

Micrasterias radiosa, made up of one cell

Amoeba proteus, made up of one cell

Cells of Allium cepa

Which of the following statements are true about the organisms shown in the micrographs above? Select all that apply.

All cells within a multicellular organism have the exact same shape.

Homo sapiens and Allium cepa are multicellular, while Micrasterias radiosa and Amoeba proteus are unicellular.

All unicellular organisms are the same species.

Cells contain small structures.
