GENERAL HISTOLOGY

Detailed explanation-1: -Eukaryotic cells are characterised by the presence of a well-defined nucleus and the membrane-bound organelles. They are larger and much more complex than prokaryotic cells which lack a well-defined nucleus and membrane-bound organelles. Two examples of eukaryotic cells are plant and animal cells.

Detailed explanation-2: -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).

Detailed explanation-3: -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-4: -Eukaryotic cells are more complex than prokaryotic cells. They all have a cell membrane, ribosomes, and DNA as prokaryotic cells do. However, the DNA of eukaryotic cells does not float freely in the cytoplasm. Instead, it is found in the nucleus, an internal compartment bound by a cell membrane.
