Plant vs Animal Cells STAAR

Cells have different sizes, structures, and functions. Some cells are so small, they can only be seen with certain tools. Which of these tools allows scientists to observe the smallest of cells?

• binoculars

• hand lens

• magnifying glass

• microscope

A student is observing a group of cells under a microscope. What observation would help her conclude that they are plant cells?

• The presence of nuclei can be clearly detected within each cell.

• The cells appear well-defined, indicating the presence of cell walls.

• The presence of mitochondria can be clearly detected within each cell.

• The cytoplasm in which the cell organelles are embedded can be clearly seen.

Imagine you made a very thin slice of the stem of a potato plant. You placed the slice on a microscope slide and looked at the stem using the 10X lens of the microscope. What would you be able to see?

• Only light would be visible.

• The stem would look the same.

• You would see the cells in the stem.

• You would see the atoms within the tissue.
