Comparison of Plant 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

metabolic activities takes place. The organelles of the prokaryotes are not membrane bound and are simpler structures. Just like organs‚ each organelle contributes in its own way to help the cell function well as a whole. The organelles are endoplasmic reticulum‚ golgi apparatus‚ mitochondrian‚ nucleus‚ chloroplast‚ vacuole‚ endosome‚ lysosome and peroxisome. If one of the organelles n the cell does not function well‚ it will give impacts towards the cell‚ especially the most important organelle like

The Nucleus: In the kingdom the nucleus is the king. The nucleus is a membrane-bound organelle found in the center of the cell that contains all of the genetic information‚ and DNA and controls the rest of the cell. To the kingdom the nucleus is the king because of how he controls the kingdom and is responsible for the wealth of the town through his actions. Additionally not all cells have a nucleus. Just as not all kingdoms have a king. The Nuclear Envelope: The nuclear envelope is similar to

functions suggest the complexity of the eukaryotic cell. The smooth endoplasmic reticulum is so named because it appears smooth by electron microscopy. Smooth ER plays different functions depending on the specific cell type including lipid and steroid hormone synthesis‚ breakdown of lipid-soluble toxins in liver cells‚ and control of calcium release in muscle cell contraction. Rough Endoplasmic Reticulum: Rough endoplasmic reticulum appears "pebbled" by electron microscopy due to the presence of numerous
