LIFE SCIENCE

Detailed explanation-1: -Eukaryotic have a more complex cell structure due to compartmentalisation of organelles. So, they need a more complex process like mitosis which also divides the organelles and cytoplasm equally among the daughter cells.

Detailed explanation-2: -The genomes of most eukaryotes are larger and more complex than those of prokaryotes (Figure 4.1). This larger size of eukaryotic genomes is not inherently surprising, since one would expect to find more genes in organisms that are more complex.

Detailed explanation-3: -Like prokaryotic cells, all eukaryotic cells are surrounded by plasma membranes and contain ribosomes. However, eukaryotic cells are much more complex and contain a nucleus, a variety of cytoplasmic organelles, and a cytoskeleton (Figure 1.7).
