Taken from AQA specification learning outcome 4.1.1.2Students should be able to explain how the main sub-cellular structures, including the nucleus, cell membranes, mitochondria, chloroplasts in plant cells and plasmids in bacterial cells are related to their functions.I find the best way to tackle this question is to create a table:Animal cells vs Plant cellsNext list all the sub cellular units inside each cellFinally add the function of each cellular sub unit to your tableSometimes quick diagram of a cell can help Most animal cells have the following parts: • a nucleus • cytoplasm • a cell membrane • mitochondria • ribosomes. In addition to the parts found in animal cells, plant cells often have: • chloroplasts • a permanent vacuole filled with cell sap. Plant and algal cells also have a cell wall made of cellulose to strengthen the cell
