Rosa uses a microscope to look at a group of cells she she sees that the cells are joined together so she knows that they are from one organism she also sees that all of them have cell walls rosa could be looking at

The correct answer will be- either a plant or a fungus

Explanation:

When Rosa look at the microscopic sample she observes two important features which are:

1. The cells are joined together which indicates that many cells are working as a single entity therefore, it is a multi-cellular organism.

2. The cells have a cell wall which is present mostly in the plants and the fungi.

Therefore the organism, Rosa is looking at will be either a plant or a fungus as they both are multicellular and possess a cell wall around the plasma membrane.

cell division is not regulated in tumor cells.
