Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan

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. While Eukaryotic cell are found inside plant and animal life. Eukaryotic are more advanced and larger. Prokaryotic cell

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

The Evolution of Eukaryotic Cells from Prokaryotic Cells DNA- Deoxyribonucleic acid (DNA)‚ a self-replicating material present in nearly all living organisms‚ is the acid that carries genetic information. RNA- Ribonucleic acid (RNA)‚ is an acid that is present in all living cells‚ it’s main role is to act as messenger and carry instructions from DNA fro controlling the synthesis of proteins. What are Eukaryotic Cells and Eukaryotic Organisms? A eukaryotic cell is a cell that contains complex

Describe the key structures and functions of a eukaryotic and prokaryotic cell. Eukaryotic Cell (1) There are many organelles in the eukaryotic cell micrograph above. Some of these organelles are displayed in the prokaryotic micrograph and so‚ I have described the shared organelles in the prokaryotic micrograph section. Mitochondria The mitochondria cells break down nutrients which then creates energy. They act like a digestive system. This process is called cellular respiration. The

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

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

Eukaryotic vs. Prokaryotic cells Prompt: Describe the similarities and differences between Prokaryotic and Eukaryotic cells. All organisms are made of cells. The cell is the simplest collection of matter that can be alive. Cells are the basic structural and functional units of every organism. Cells fall into two distinct types: Prokaryotic and Eukaryotic. While Prokaryotic and Eukaryotic cells are similar in that both types of cells are bounded by a plasma membrane‚ all contain cytosol‚ and all

and Animal Cells Introduction Eukaryotic cells are very complex; there are many organelles‚ each serving a distinct function‚ present in eukaryotic cells. We can divide the eukaryotic group of cells in to two main groups‚ according to the presence of these membrane bound organelles‚ and the structural differences amongst the cells and their organelles. The two groups of eukaryotic cells are plant and animal cells. Nucleus The reason that plant and animal cells are not divided in to two different

have in common would be cells. In fact every living thing is composed of cells: plants‚ animals‚ bacteria etc. Cells exist in different shapes and sizes. They also differ depending on the function they have in an organism. To make things simpler‚ cells are categorized into two vast groups: Prokaryotic and Eukaryotic Cells. These two types of cells are different from each other while still sharing some similarities. Eukaryotic and Prokaryotic Cells perform the same functions in the same way‚ both also
