The Animal and Plant Cell - Essay Example There are a number of similarities that are possessed by the two cells and which perform closely related functions in either cell. First, both cells possess a cell membrane. A cell membrane is the covering that protects the inner organelles of the cell from damage. The cell membrane in both cells has certain properties that make it perform its functions in the best way. For instance, it’s semipermeable to allow partial passage of particles or what is called selective permeability. This is important in preventing particles to get into the cell and the ones that are supposed to remain from leaving. This helps in maintaining the osmotic pressure of the cell and ensuring that it is turgid as in guard cells which control the gaseous exchange of plants. Both cells contain mitochondria. The mitochondria are the power organelle that is responsible for generating the energy that is used in the cell and also in the activities that the organism engages in. It has enzymes (protein catalys ts) which are able to convert simple food materials such as carbohydrates, proteins, and lipids into high energy molecules such as the Adenosine Triphosphate (ATP), Guanine Triphosphate (GTP) and Cytosine Triphosphate (CTP). This high energy molecule is generated in the various cycles e.g. the Kreb's cycle which take the food materials as the raw materials. This is a very important organelle as without it the organism would not be able to generate energy and hence its activity would be totally impaired.
