![]() Compare and contrast the eukaryotic cell shown here with the prokaryotic cell. Ribosomes, the organelle where proteins are made, are the only organelles in prokaryotic cells.Įukaryotic Cell. This allows eukaryotic cells to have greater cell specificity than prokaryotic cells. Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Eukaryotes, on the other hand, contain complex double membraned organelles, complex DNA (arranged on chromosomes), and a nucleus. Prokaryotic cells contain simplified ribosomes which free float in cytoplasm all bound by a cell membrane and wall. Organelles called mitochondria, for example, provide energy to the cell, and organelles called vacuoles store substances in the cell. A nucleoid region contains a loop of nucleic acids known as a DNA plasmid. An organelle is a structure within the cytoplasm that performs a specific job in the cell. Organisms with eukaryotic cells are called eukaryotes, and they range from fungi to people.Įukaryotic cells also contain other organelles besides the nucleus. Eukaryotic cells are usually larger than prokaryotic cells, and they are found mainly in multicellular organisms. A typical eukaryotic cell is shown in Figure below. And it all depends on how the cell stores its DNA.Įukaryotic cells are cells that contain a nucleus. In fact, all cells other than bacteria will be one type, and bacterial cells will be the other. Can you tell which depicts various types of bacteria? However, all cells - whether from bacteria, human, or any other organism - will be one of two general types. And the largest distinction between a eukaryote and a prokaryote are membrane-bound structures that eukaryotes have that prokaryotes don't have. Here we have drawings of bacteria and human cells. For example, in you there are blood cells and skin cells and bone cells and even bacteria. How many different types of cells are there?
