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: -Unlike eukaryotic cells, prokaryote cells lack membrane-bound organelles. However, whereas prokaryote cells are less structurally complex than eukaryotes, they are more chemically complex, since all of the prokaryote cell’s biomolecules are floating around together.

Detailed explanation-3: -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.

Detailed explanation-4: -Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and they do not contain cytoplasmic organelles or a cytoskeleton (Table 1.1).

Detailed explanation-5: -Prokaryotic cells are very simple and primitive. They have no true nucleus, and have no membrane-bound organelles. Prokaryotes simply have a cell membrane that encloses the contents, often a cell wall around the cell membrane, genetic information and ribosomes to make proteins all inside the cytoplasm.
