Question

what is meant by division of labour in cell???

Answer 1

 The eukaryotic cells are much more complex than prokaryotic cells. The most obvious difference is the variety of structures in the cytoplasm. Most of these structures are composed of membranes. In eukaryotes, membranes partition the cytoplasm into compartments, which biologists call membranous organelles. Many of the chemical activities of cells activities known collectively as cellular metabolism-occur in the fluid filled spaces within membranous organelles. These spaces are important as sites where specific chemical conditions are maintained, conditions that vary from one organelle to another. Metabolic processes that require different conditions can take place simultaneously in a single cell because they occur within separate organelles. For example, while the endoplasmic reticulum is engaged in making a steroid hormone, neighboring peroxisomes may be making hydrogen peroxide (H2O2) as a poisonous by-product of certain metabolic reactions only because the H2O2 and the steroids get protected from destruction. Another benefit of internal membranes is that they greatly increase a eukaryotic cell's total membrane area. 
So sinle cell but still having organelles to perform distinct functions...Division of labour!!!Source(s):VPM Signature of Biology.
