GENERAL HISTOLOGY

Detailed explanation-1: -Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms. Protozoa, fungi, plants, and animals all have eukaryotic cells.

Detailed explanation-2: -Eukaryotic cells are generally larger and more complex than prokaryotic cells. They also contain a variety of cellular bodies called organelles. The organelles function in the activities of the cell and are compartments for localizing metabolic function.

Detailed explanation-3: -However, eukaryotic cells are much more complex and contain a nucleus, a variety of cytoplasmic organelles, and a cytoskeleton (Figure 1.7). The largest and most prominent organelle of eukaryotic cells is the nucleus, with a diameter of approximately 5 m.

Detailed explanation-4: -A new type of cell, known as a eukaryote, emerged. The eukaryotes would evolve many complex internal modules or organelles, including the endoplasmic reticulum, the Golgi apparatus and the mitochondria, forming wildly diverse cell types-precursors to all subsequent plant and animal life on Earth.

Detailed explanation-5: -Additionally, eukaryotic cells are more than 100 to 10, 000 times larger than prokaryotic cells and are much more complex. The DNA in eukaryotes is stored within the nucleus, while DNA is stored in the cytoplasm of prokaryotes.
