Function key Cell membrane Cytoplasm Nucleus Nucleolus Smooth endoplasmic reticulum Ribosomes It allows selective substances to move in and out of the cell and is partially permeable. It is a jelly-like liquid in the cell where chemical reactions take place and where all organelles and cell parts are contained. Controls activities of the cell and contains chromosomes which are essential for cell division. Production of ribosomes and synthesis of ribosomal RNA (rRNA) This regulates and releases calcium ions and processes toxins Involved in protein synthesis Function key Golgi Body This organelle gathers simple molecules and makes more complex molecules. It can create things to store for later, send them out of the cell, and create lysosomes to name a few functions Vacuoles Stores air, water or food in the cell. Mitochondria Conducts respiration for the cell to get energy. Lysosomes Act as an digestive and immune organelles Rough endoplasmic reticulum In between the layers of the smooth and rough endoplasmic reticulum, protein molecules are synthesized and collected, and once enough are collected, the proteins are pinched off into things called vesicles, which are basically shuttles of some sort, although there are multiple types of vesicles.
