Item CE033002: When looking through a microscope at leaf and root samples, one would see that both are made of cells.
What would a biologist see if she examined a small piece of a leaf from a plant and a small piece of a root from the same plant through a microscope?
- Both the leaf and the root would be made up of cells.
- The leaf would be made up of cells, but the root would not be made up of cells.
- The root would be made up of cells, but the leaf would not be made up of cells.
- Neither the root nor the leaf would be made up of cells because plants are not made up of cells.
