Document Summary
Intracellular: inside the cells (can be specialised, e. g. intravascular in blood capillaries) Cytoplasmic inclusions: aggregates of chemicals made in the cell or transported into the cell. Responsible for changes to cell shape and movement of organelles. Microtubes, microfilaments and intermediate filaments are made up of proteins and provide structural support and mechanical strength. Nucleolus: dense structure that primarily produces ribosomes from rna. Physiology is the study of the function of cells. Rough and smooth er is continuous, joins together. Modifies packages and distributes proteins and lipids made in the rough er. Membrane bound vesicles that form at the golgi apparatus. Digest molecules no longer needed by cell, e. g. proteins, lipids, nucleic acids, carbs, etc. Has its own genetic material, can reproduce itself. Barrel shaped organelles at right angles to one another. When they are perpendicular, they form the centrosome. Two centrioles can be found in the centrosome (cell centre)
