Astudent observes this cell under the microscope. he is discussing the structure indicated by the arrow with his lab partner. what would be the most likely classification of the cell pictured based on the structure they are observing?

This cell is eukaryotic because it contains membrane-bound organelles such as lysosomes and vacuoles.

Eukaryotic cell.  

Explanation:

The eukaryotic cells are those cells, in which true nucleus is present along with other membrane-bound organelles, such as lysosomes, endoplasmic reticulum, mitochondria, and chloroplast (in case of plant cells).

As in given diagram, the arrows represents membrane-bound organelle, lysosome, this picture can be classified as an eukaryotic cell.
