A student is examining a cell through a microscope. She notes the following cell parts: cell membrane, cell wall, chloroplast, large vacuole, mitochondria, cytoplasm, & nucleus.  What type of cell is the student looking at?     7.12D

• A plant cell because only plant cells have cytoplasm.
• An animal cell because only animal cells have large vacuoles.
• A plant cell because only plant cells have a cell wall and chloroplasts.
• She can’t be sure because both plant and animal cells have those cell parts.
