F: Endoplasmic reticulumWhat is a Microscope?A Microscope may be defined as a type of laboratory instrument which is utilized to observe small things that are too small to be visualized by the unaided eyes. This type of instrument is typically used to view cellular functions and structures.
A large central vacuole accounts for almost 90% of the plant cell volume. The Cell wall of the plant is made up of cellulose. Mitochondria deliver energy that is needed by the cell in order to accomplish metabolic activities. A Chloroplast is a membrane-bound cell organelle that facilitates the process of photosynthesis.
Therefore, the terms that correctly identify the indicated structures in this sketch of a cell viewed under a microscope are well mentioned above.
