Compare and Contrast, Eukaryote and Prokaryote Cells

Extracts from this document...

Introduction

´╗┐The Prokaryotic and Eukaryotic cell. In the early 1950?s, building on Darwin?s idea of a ?warm little pond? giving rise to the first life (99% Ape), Stanley Miller, at the University of Chicago, introduced sparks of electricity, simulating lightening, to a mixture of gases and other substances thought to have made up the earths early atmosphere and oceans, in order to see if this was in fact how the first life began. This experiment, and similar, have thus far turned up nothing more than the formation of some amino acids.(Bill Bryson) Further research has given scientists a more well formed idea that the first signs of life would have arisen at the bottom of the ocean around hydrothermal vents(Nick Lane). Whichever theory proves true, life started off with just a few positively tiny things. It is thought that these amino acids would have arranged into macromolecules such as proteins and amino acids, which are crucial building blocks of life.(NCBI) ...read more.

Phospholipids are made up of a phosphate head which is hydrophilic, and as such can face towards the water on both the outside and the inside of the cell, with the hydrophobic fatty acid tails facing in towards each other. In both cases, this layer is responsible for isolating the cells contents from the outside world, and allowing transport into and out of the cell, as well as providing a shape for the cell. It is arranged in what is known as the ?Fluid Mosaic Model?. This is due to the arrangement of proteins set within the two phospholipid layers, which can move freely around within the membrane. Prokaryotic cells are also contained within a cell wall, as well as a cell membrane, a feature found in some eukaryotic cells. Another feature sometimes shared by prokaryotic and eukaryotic cells are flagella, which are small projections from the cell which enable locomotion. ...read more.

Conclusion

They both contain an organelle known as the endoplasmic reticulum, takes part in synthesising proteins and lipids, in the rough and smooth endoplasmic reticulum respectively, and send them off to the Golgi apparatus. In both plant and animal cells, this is the organelle responsible for processing proteins, and enzymes, and is also involved in producing lysosomes - a very small organelle responsible for ridding the cell of waste organelles and involved in the destruction of the cell itself (Class notes).

    The society seems to have democracy. In reality, the problems of the workers aren't taken seriously, and people in the higher class don't care the workers' problems. In addition powerful and selfish men like Slackbridge and Bounderby are self-centered. They want to show their power and dictation.
