In this task I will outline the functions of the main cell components. Which consists of the Cell membrane, nucleus, cytoplasm, mitochondria, endoplasmic reticulum (smooth and rough), golgi apparatus and lysosome. Cells are the structural and functional units of all living organisms. Cells can take in nutrients, change these nutrients into energy and can carry out particular functions, and reproduce them if needed. Mitochondria Mitochondria Nucleus Nucleus Lysosome Lysosome Golgi apparatus Golgi apparatus Cell membrane Cell membrane Endoplasmic reticulum (Smooth and rough) Endoplasmic reticulum (Smooth and rough) Cytoplasm Cytoplasm Cell Membrane A cell membrane of the cell.
Depending on the contents these are despatched to one of three destinations: Cytoplasm-The cytoplasm consists of all of the contents outside of the nucleus and enclosed within the cell membrane of a cell. This includes the cytosol and in euckaryotic cells, organelles such as mitochondria and ribosomes. Also located within the cytoplasm is the cytoskeleton, a network of fibers that help the cell maintain its shape and give it support. The cytoplasm is clear in colour and has a gel-like appearance. It is composed mainly of water and also contains enzymes, salts, organelles, and various organic molecules.
| Goigi Apparatus | The main function of the Golgi apparatus is to be responsible for handling the macromolecules that are required for proper cell functioning | It packages and ships molecules made in the ER. | Lysosome | Lysosomes are spherical bag like structures that are bound by a single layer membrane, however, the lysosome shape and size may vary to some extent in different organisms. The lysosome size ranges between 0.1 to 1.2μm. | Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. | P1 tasks 2 Organs | Anatomy | Physiology
Cells are the building blocks of life. Tissue: Made from similar cells. Each organ has specific types of cells that make that particular organ and its parts. Organ: Similar types of tissue (example brain tissue, muscle tissue, bone tissue, heart tissue) makeup an organ. Organ System: Organs that work together to help an organism execute a specific function (breathing, thinking, eating, reading, writing, playing, learning, sleeping, moving, etc.)
The nuclear membrane has a similar structure to the cell membrane but it contains gaps which allow protein to pass through. The nucleus controls almost all of the activities of the cell. Cytoplasm: The cytoplasm refers to anything which is inside the cell boundary and outside the nucleus. It is a semi-fluid material which is capable of flowing slowly. Many chemical reactions are carried out in the cytoplasm.
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 | |
What aspects of cell membrane structure are accurately illustrated by it? * Describe the structure of the cell membrane according to the fluid mosaic model. * What class of biological molecules do enzymes fit into: carbohydrates, lipids, proteins, or nucleic acids? How do enzymes work? What do they do?
| Vesicle | Storage in and out of the cell. | Cytoskeleton | The cytoskeleton plays a critical role in the determination of cell shape and serves as a scaffold for critical cellular enzymes and adhesion molecules. It provides structural integrity for the cell and regulates the function of many biochemical events that are critical to cellular function.
The nucleus regulates all cell activity and is bounded by a double membrane called the nuclear envelope, this membrane separates the contents of the nucleus from the cytoplasm. The Nucleus have two major functions. It stores the cell’s hereditary material, or DNA and it co-ordinates the cell’s activites, which include metabolism, growth, protein synthesis, and reproduction (cell division). ‘Mitochondria are the cell’s power producers’ Bailey, About.com. They convert energy into forms that are usable by the cell.
