Slide 14:Cytoplasm Outer Surface Change rate of Energy Production
(Metabolism) Direct a cell to change shape or
move in a particular direction Can enter the nucleus and
“Alter Gene Expression” Activation of Intracellular Signalling Proteins
Example :Example To describe the importance of communication and explain the process.
Defence mechanism by which white blood cells, called Neutrophils defence the body.
