Marsha is looking at the cross-section of a stem under a microscope. Based on the plant tissues seen here, Marsha is most likely looking at Meristematic tissue.

Explanation:

Meristematic tissue can be seen only through microscopic because it is present at the tip of the root. It is the area where the roots are grown and the dividing cells are produced. Meristematic is a type of plant tissue where the cell division takes place. The other type of plant tissue is the permanent tissue, these are the tissue that can not take place in cell division.
