प्रश्न
What is the utility of tissues in multi-cellular organisms?
उत्तर
In unicellular organisms, a single cell performs all the basic functions, such as respiration, movement, excretion, digestion, etc. But in multicellular organisms, cells are grouped to form tissues. These tissues are specialised to carry out a particular function at a definite place in the body.
- For example, muscle cells form muscular tissues, which help with movement, and nerve cells form nervous tissue, which helps transmit messages.
- This is known as the division of labour in multicellular organisms. Because of this division of labour, multicellular organisms can perform all functions efficiently.
