414 Words 2 Pages
Cell membrane- A cell membrane is a fine structure that can also be referred to as a plasma membrane. Both Eukaryotic and prokaryotic cells are enclosed by a cell membrane. The functions are to keep a steady shape of the cell and to control particles moving into and out of the cell. These particles may be ions or molecules.
Cell wall- Prokaryotic cells have a cell wall whereas eukaryotic cells don’t. The cell wall is what provides shape and protects the cell components.
Nucleus- Nucleus is only found in eukaryotic cells. The structure of a cell’s nucleus is membrane bound and contains chromosomes which consist of DNA. The nucleus maintains the integrity of genes and controls the activities of the cell. The nucleus is referred to as the control centre.
Mitochondria- Prokaryotic cells do not have mitochondria whereas eukaryotic cells do. They are made up of two membranes. The outer membrane acts as the

The role is to form proteins by assembling amino acids. The proteins are needed to carry out the cells activities.
Endoplasmic reticulum- These are only found in eukaryotic cells. It is made up of sac like structures and held together by a cytoskeleton. Rough endoplasmic has a surface dotted with proteins and the smooth endoplasmic is made up of tubules which increases surface area. They insure there is more surface area for cell reactions. Also involved in making nuclear membranes during the division of cells. Carbohydrates and proteins are transported to different organelles including lysosomes and plasma membrane.
Golgi body- they are only found in eukaryotic cells. It is made up of sac like membranes which are stacked. The structures are known are cisternae. The main role is to sort, package and modify molecules that have been synthesized by cells. They also create lysosomes and transport lipid
