Merits & Demerits of Complexity in Higher Organisms - SS1 Biology Lesson Note

MERITS OF COMPLEXITY IN HIGHER ORGANISMS

1. It leads to cellular differentiation and specialization

2. It leads to biological efficiency in higher organisms akin to the concept of division of labour in economics

3. It leads to an increase in the size of organisms

4. It leads to adaption in the environment

DEMERITS OF COMPLEXITY IN HIGHER ORGANISMS

1. It leads to the inability of cells to exist on their own

2. It leads to increased difficulty in the acquisition of oxygen and food materials

3. It leads to slower rates of cellular diffusion

4. It leads to slower rates of expulsion of waste

5. It leads to difficulty in reproduction

6. It leads to a decrease in the ability to regenerate
