The statement is correct. We all are made up of similar types of cells but not all cells are the same.Different cells have different shapes and sizes depending on their function. For example, nerve cells have a branched shape for transferring information. All the organelles shown in the typical cell are not found in every cell. Depending on the need of the organelle, the presence or absence of the organelles and their number differs. For example, cells involved in photosynthesis may contain around 50 to 200 chloroplasts.
