Living cells are of two major types, prokaryotes and eukaryotes. About 2 billion years ago only prokaryotes inhabited our world. The main difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus and prokaryotes don't. In biology, "pro" means "before" and "eu" means "tru...
1. Prokaryotes and eukaryotes differ in size and the presence of a membrane-bound nucleusProkaryotic cell The DNA in a prokaryotic cell is usually located in a region called the nucleoid.Prokaryotic cells comprise bacteria and archaea. They typically have a diameter of 0.1–5 μm, and their ...
Eukaryotes are organisms whose cells have a nucleus and other organelles enclosed by a plasma membrane. Organelles are internal structures responsible for a variety of functions, such as energy production and protein synthesis. The key structures present in a eukaryote cell. Credit: Technology...
Describe the structure, composition, and function of ribosomes. Explain the difference between prokaryotic and eukaryotic cells. Describe the functions of the following organelles: (a) Ribosome, (b) Nucleus. What do all eukaryotes have that prokaryotes do not? a. Cell membrane b. Nucleus c. Cyt...
There are two main types of cells, prokaryotes and eukaryotes. Prokaryotes are cells that lack a nucleus and membrane-bound organelles. They have a more simple structure and include bacteria and archaea. Eukaryotic cells, however, do have a nucleus and membrane-bound organelles. The purpose of ...

directions at the same time, and takes place in the cell cytoplasm. Eukaryotic cells on the other hand, have multiple points of origin, and use unidirectional replication within the nucleus of the cell. Prokaryotic cells possess one or two types of polymerases, whereas eukaryotes have four or ...
