What is the difference between prokaryotic cells and eukaryotic cells? What are the names for the two major groups of prokaryotes? both have a cell membrance on the outside and both have ribosomes but the eucaryotic only have membrane bound organelles. both can have the cell wal. euc.
| | | D) | All living organisms are composed of one or more cells. | | | | | | Feedback: Cell theory states: all living things are made of cells; cells basic units of structure and organization; cells arise only from previously existing cells. Most prokaryotic cells do not have specialized internal structures. | | 2 CORRECT | | A ____ contains polar and nonpolar ends, forming the plasma membrane. | | | A) | microtubule | | | B) | transport protein | |
The endoplasmic reticulum (ER) is a system of interconnected membranous sacs, channels, or cisternae in the cytoplasm. It has two subtypes: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The RER is a ribbon-like structure surrounding the nucleus near the base of the cell. Its surface appears rough due to the ribosomes attached to its membrane and it is the first organelle into which membranebound or extracellular proteins are inserted. SER lacks ribosomes and participates in lipid synthesis and detoxification.
Parasites are part of a large group of organisms called eukaryotes. They are different from bacteria & viruses because their cells share many features with human cells including a defined nucleus. They are usually larger than bacteria, although some environmentally resistant forms are nearly as small. Some parasites only replicate within a host organism, but some can multiply freely in the environment. Parasites can be made up of one cell, as in the case of Giardia, or many cells, as with parasitic
Bacteria reproduces by most commonly occurs by a kind of cell division called binary fission. Binary fission results in the formation of two bacterial cells that are genetically identical. 6. The Archaea these microbes are prokaryotes, meaning that they have no cell nucleus or any other membrane-bound organelles within their cells. 7.
Plant and Animal cells Introduction: Cells can be all shapes and sizes; they form the basic structure of the plant or animal. Cells also help living things stay alive, and each organelle in the cell has its own function. There are two main types of cells: Eukaryotic cells (cells with a nucleus), and Prokaryotic cells (cells without a nucleus). The aim of this report is to explain cell theory, to compare and contrast animal and plant cells. I will also include comparisons of the organelles to a factory to help better understand the works of a cell.
| | Cells | Cells are the smallest functional unit organism. Cells have many different functions inside of living things. | | Eukaryotic | An Eukaryotic cell is a cell that has a nucleus and all of the organelles in the inside are protected by a cell membrane. | | Prokaryotic | Prokaryotic cells don't have a nucleus. | | Cell Membrane | The Cell Membrane holds everything inside the cell together and protects it from things that could harm it.
Fungi are Eukaryotes, when compared to prokaryotic. Fungi are eukaryotic multicellular organisms. Fungi cells have a cell wall that contains chitins, but the wall
Many chemical reactions are carried out in the cytoplasm. Glycogen and melanin are found in the cytoplasm. Organelles: Organelles are different components of a cell and have a distinct structure and their own functions. They can be likened to miniature organs. Organelles include mitochondria, Iysosomes, the Golgi apparatus and the endoplasmic reticulum.
This brings our attention that “what is life?” As the science of biology, indicated to us that metabolic processes involve special macromolecules very large molecules consisting of long chains of hundreds of atoms. These long chains consist of protein and nucleic acid (DNA, RNA) which is present in all cells (Luisi, 1998). Bacteria cell has two
