Prokaryotic and Eukaryotic Cells Cells are the basic building block of life. Cells can be either Eukaryotic or Prokaryotic cells. Organism can only contain either one but not both of them. Prokaryotic cells are usually much smaller than Eukaryotic and are less complex. Bacteria are made up of one or more prokaryotic cells. Bacteria are made up of one or more prokaryotic cells.

Cell Structure

each structure identified, do you think its location affects its ability to function? Why or why not? (Hint: those buried deep in the cell probably do different things than those closer to the cell membrane). Structure does not affect function of the cells, cells have a particular structure that enables them to carry out their function in the best way. 2.

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...

Eukaryotic & Prokaryotic Cells

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. This is a diagram of a prokaryote cell and it shows that they are not very complex cells. They do not contain any membrane...

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms, which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant...

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...

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.
