FLAGELLUM = long tail-like structure for cell locomotion. MITOCHONDRION = "powerhouse" of the cell (produces ATP). CHLOROPLAST = site of photosynthesis. AMYLOPLAST = stores starch in plant cell. CENTRIOLE = produces spindle fibres for mitosis. PROTOPLASM = supports all cell organelles. CELL MEMBRANE = semipermeable to control enter and exit of materials. NUCLEOLUS = produces ribosomes.
