Cell division is the process in which the cell divides into two or more daughter cells whereas cell differentiation is a process in which embryonic cells become specialized cells according to their function.
DNA amount changes in cell division but no change in DNA in cellular differentiation.
Explanation:
During cell division, either mitosis or meiosis will take place in somatic or germ cells resulting in 2 diploid and 4 haploid cells respectively. The daughter cells are responsible for repairing or gamete formation. The amount of DNA content doubles in cell division.
In cell differentiation cells become specialized for the functions they have been destined like blood cells, nerve cells etc. Different types of cells are formed because different genes are expressed for the specific function. Hence, there will be no change in DNA only the sequence of DNA dictates the specialized cell for the particular function.

Answer:
Charles Robert Darwin was a British naturalist and biologist known for his theory of evolution and his understanding of the process of natural selection
Explanation:
2. <u>Some of these variations are passed on to offspring;</u>
- As the genetic changes may occur due to mutations in the genes.
- As these changes do not occur in days or months but they occur after hundred and thousands of years.
- The off springs are distinct from their ancestors. This results in the formation of new species. Gradual modification of the existing species leading to the formation of new species is known as speciation.
4<u>.Individuals vary in their ability to survive and reproduce</u>;
- Those with the most favorable adaptations are more likely to survive and reproduce.
- Individual variation (usually through mutation) may introduce traits or abilities that enable that individual to survive in order to reproduce. Usually these are tiny incremental changes that accumulate over centuries or millennia.
<u>Note:</u><em> However there are certain drawbacks of Darwinism even such as it failed to explain the basis of variation and the mode of transmission of characters.
