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 were the first to live on earth they appeared around 3.5 billion year ago and the Eukaryotic appear around 2.1 billion year after (Campbell Essential Biology, 2012).

The eukaryotic structure consists of the following organelle which includes mitochondria, chloroplast, the endoplasmic reticulum, the Golgi apparatus, lysosomes and nucleus. These organelles perform a specific function that help the cell survive. The organelles are separated from the rest of the cellular space by a membrane; it is like having a separated room in a home. The nucleus is the most critical part of the eukaryotic cell. The nucleus house most of the eukaryotic cell’s DNA and is surrounded by a double membrane. A prokaryotic cell lack a nucleus it DNA is coiled into a nucleus-like region called the nucleoid, which is not partitioned from the rest of the cell by membrane (, Campbell Essential Biology 2012).

The two organelles that work as a cellular power station are chloroplast and mitochondria. The chloroplast which are unique to the photosynthetic cells of plant and algae, are the organelles that perform photosynthesis. The chloroplast consist of three major parts the internal membrane which surround the chloroplast, the stroma is a thick fluid within the chloroplast, the grana is a solar power that trap light energy and convert it into energy. The mitochondria are the organelle of cellular respiration in all that harvest energy from sugar and other food molecule and it produce a form of...
