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.
Just as when we grow and need more food and energy so does a cell. when a cell is growing there is more of it that can be utilized putting more stress on the DNA to code whatever it needs. The bigger the cell is the denser and thicker the cell membrane gets making it harder for materials to work its way in and out of the cell.
