Answer:
The correct answer will be- either a plant or a fungus
Step-by-step 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.
