Answer» In multicellular organisms, several cells are GROUPED to FORM tissues. These tissues perform PARTICULAR function at a definite place in the body. For example, nerve cells from the NERVOUS TISSUE which helps in transmission of messages. This is known as division of labour in multicellular organisms.
