Microfilaments and Intermediate filaments (Mf, If)—form the cytoskeleton, in combination with microtubules to bring about shape changes and cell movement.
Microtubules (Mt)—dynamic cytoskeletal components, which are constantly assembled and broken down to provide rigidity within the cytoplasm, and act as ‘rails’ for intracellular transport.
Mitochondria (Mi)—are the sites of energy generation for all cellular activity.Nucleus (Nu)—contains the ‘blueprint’ for all cell activity, stored in code on the DNA, which necessitates constant and intense interaction with the cytoplasm.
