Eukaryotic & Prokaryotic Cells Introduction: The Cell: The cell is a functional unit of all living organisms. Cells have evolved into two fundamentally different types, eukaryotic and prokaryotic, which can be distinguished on the basis of their structure and the complexity of their organization. The simplest organisms which consist of one cell are called prokaryotes. More complex organisms are called eukaryotes and they consist of many cells. Objectives: * Define the terms: Eukaryotes...

Compare and contrast the structure and function of prokaryotic and eukaryotic cells.

 Prokaryotic cells are single celled organisms that were formed at the formation of the earth, so are the most basic life forms. The prokaryotes are organised in the ‘three domain system’ and include bacteria and blue-green algae. Prokaryotes live in many environments including extreme habitats such as hydrothermal vents, hot springs, swamps, wetlands, and the guts of animals.

Eukaryotic Cell

1. Eukaryotic cells have a true nucleus, bound by a double membrane. Prokaryotic cells have no nucleus. The purpose of the nucleus is to sequester the DNA-related functions of the big eukaryotic cell into a smaller chamber, for the purpose of increased efficiency. This function is unnecessary for the prokaryotic cell, because its much smaller size means that all materials within the cell are relatively close together. Of course, prokaryotic cells do have DNA and DNA functions. Biologists describe...

Eukaryotics Cells

Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name, (also spelled "eucaryote,") which comes from the Greek word referring to the nucleus. Animals, plants, fungi, and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the...

THE ORGANELLES OF EUKARYOTIC CELLS . The difference between Prokaryotic and Eukaryotic Cells is organelles, membrane enclosed structures that perform specific duties. The most important of all is the “nucleus,” this holds the DNA and is surrounded by a double membrane. The Prokaryotic lacks a nucleus which is not partitioned from the other cells by membranes. The region between the nucleus and plasma membrane is called cytoplasm and in the Eukaryotic cell it consists of various...

life’s hierarchy, cells make up the lowest level of organization. Cells can perform activities required to sustain life. A cell’s ability to divide to form new cells is the basis for growth and repair in organisms. Cells also play a key role in the recycling of carbon, a chemical element essential to life, and also participate in cellular processes such as photosynthesis. With these points in mind, it should be noted that cells come in one of two forms: prokaryotic and eukaryotic. By investigating...
