Multicellular organisms have division of labour, Explain

(a) The division of labour in multicellular organisms is best represented by the presence of several types of organ system in the body.
(b) The cells in multicellular organisms originate by the division of single-celled zygote. These newly formed cells are specialized to perform specific function and a division of labour is established between these cells which co-exist in the body of the multicellular organisms.
© Division of labour provides better co-ordination
and organisation to multicellular organisms. Thus specialised structure performes different functions in the body.
