2.3: Eukaryotic Cell: Structure and Function

A prokaryote is a cellular organism that lacks an envelope -enclosed nucleus. Organisms with nuclei are placed in a third domain, Eukaryota. Prokaryotes lack mitochondria , or any other eukaryotic membrane-bound organelles ; and it was once thought that prokaryotes lacked cellular compartments , and therefore all cellular components within the cytoplasm were unenclosed, except for an outer cell membrane. But bacterial microcompartments , which are thought to be primitive organelles enclosed in protein shells, have been discovered, [6] [7] along with other prokaryotic organelles. Others, such as myxobacteria , have multicellular stages in their life cycles. Molecular studies have provided insight into the evolution and interrelationships of the three domains of life. Distinctive types of prokaryotes include extremophiles and methanogens ; these are common in some extreme environments.


-eukaryotic cell, chromosomes are contained in a membrane-enclosed organelle, the nucleus. -prokaryotic cell, the DNA is concentrated in the nucleoid without.

Describe the purpose of mitosis and how it is used in living things 3. This is called cell specialism. The outer membrane is. Specialized organelles.

The cell from Latin cella , meaning "small room" [1] is the basic structural, functional, and biological unit of all known organisms. Cells are the smallest units of life, and hence are often referred to as the "building blocks of life". The study of cells is called cell biology , cellular biology, or cytology.

4.3A: Characteristics of Eukaryotic Cells

During the s, scientists developed the concept that all organisms may be classified as prokaryotes or eukaryotes. The cells of all prokaryotes and eukaryotes possess two basic features: a plasma membrane, also called a cell membrane, and cytoplasm. However, the cells of prokaryotes are simpler than those of eukaryotes.

Cells fall into one of two broad categories: prokaryotic and eukaryotic. However, prokaryotes differ from eukaryotic cells in several ways. Figure 1. This figure shows the generalized structure of a prokaryotic cell. A prokaryotic cell is a simple, single-celled unicellular organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid Figure 1.
