1: Celliberty High School | "We can learn a lot from organelles. Some make energy, some hold everything together and some are big and some are small. Some have weird names and all are different colors, but they all have to live in the same cell." -Robert Hooke,
2: Princpal Robert Hooke He is the scientist first to examine a cell using a thin slice of cork under a microscope. | Principal's Corner
3: Assistant Principal Rudolf Virchow German known for his advancement of public health.Virchow is credited with multiple important discoveries. Virchow's most widely known scientific contribution is his cell theory, which built on the work of Theodor Schwann. He is cited as the first to recognize leukemia cells. He was one of the first to accept the work of Robert Remak who showed that the origins of cells was the division of preexisting cells. He did not initially accept the evidence for cell division, believing that it only occurs in certain types of cells. ("every cell originates from another existing cell like it.") . (The epigram was actually coined by Franois-Vincent Raspail but popularized by Virchow.) It is a rejection of the concept of spontaneous generation, which held that organisms could arise from non-living matter. It was believed, for example, that maggots could spontaneously appear in decaying meat; Francesco Redi carried out experiments which disproved this notion and coined the maxim Omne vivum ex ovo ("every living thing comes from a living thing" — literally "from an egg"), Virchow (and his predecessors) extended this to state that the only source for a living cell was another living cell.

6: 1.Nucleus Main control center of the cell, stores all the genetic information of the organism. 2.Nucleolus Where all the DNA is stores, is used for cellular reproduction, inside the Nucleus 3.Golgi Packages maromolecues for transport to other places in the cell. 4.Lysosomes Contain hydrolytic enzymes that are neseccary for cellular digestion. 5.Peroxisomes Protect the cell from the waste product of hydrogen peroxide. 6.Cell Membrane The outer protective coating of a cell, let certain things in and certain things out. 7.Mitochondrion Provide the cell with energy 8.Vacuole Stores waster products and nutrients, gives the cell its shape.
7: 9.Cell Wall Rigid protective wall that give cell shape and protects it 10.Chloroplasts Give the cell its green color and used in photosynthesis. 11.Ribosomes Where protein syntheis, where RNA is translate into Protein, occurs 12. Endoplasmic Reticulum 1. Smooth Produces hormones and secretory products. 2. Rough used to transport ribosomes throughtout the cell 13.Cytoskeleton Help the cell maintain its shape. 14.Microtubes Help support the shape of the cell
8: "Cell membranes open the door, but organelles must work by themselves."

12: Vice Principal's corner | Vice Principal Matthewis Schleiden a German botanist and co-founder of the cell theory, Born in Hamburg. Schleiden preferred to study plant structure under the microscope. While a professor of botany at theUniversity of Jena, he wrote Contributions to Phytogenesis , in which he stated that the different parts of the plant organism are composed of cells. Thus, Schleiden and Schwann became the first to formulate what was then an informal belief as a principle of biology equal in importance to the atomic theory of chemistry. He also recognized the importance of the cell nucleus, discovered in 1831 by the Scottish botanist Robert Brown, and sensed its connection with cell division.win's theory of evolution. He became professor of botany at the University of Dorpat in 1863. He concluded that all plant parts are made of cells and that an embryonic plant organism arises from the one cell. He died in Frankfurt am Main on 23 June 1881.
13: Theodor Schwanna: A German physiologist. His many contributions to biologyinclude the development of cell theory, the discovery of Schwann cells in the peripheral nervous system, the discovery and study of pepsin, the discovery of the organic nature of yeast, and the invention of the term metabolism.work towards a physico-chemical explanation of cells. Schwann's rediscovery of the cell came when he was paying particular attention to the cytoplasm of a plant cell, and noticed its jelly-like consistency. He went on to view animal cells, and noted that they had different properties. he discovered the organic nature of yeast. In fact, the whole germ theory of Pasteur, as well as its antiseptic applications by Lister.
14: Our classroom rules The Cell Theory and School Expectations Homeostasis | 1.All living organisms are made up of one or more cells. 2.Cells are the basic unit of life. 3.All cells arise from pre-existing cells. 3.The cell is the unit of structure, physiology, and organization in living things. 4.The cell retains a dual existence as a distinct entity and a building block in the construction of organisms. 5.New cells are created by old cells dividing into two.
15: Homeostasis: A cell must maintain homeostasis in order to function properly. Cells use osmosis, diffusion, passive transport, and active transport in order to maintain homeostasis. If a cell cannot maintain homeostasis, it will die.
17: Cell Membrane Policy The cell membrane surrounds the cytoplasm of a cell and, in animal cells, physically separates the intracellular components from the extracellular environment. Fungi, bacteria and plants also have the cell wall which provides a mechanical support for the cell and precludes the passage of larger molecules. The cell membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. The membrane is differentially permeable and able to regulate what enters and exits the cell, thus facilitating the transport of materials needed for survival. The movement of substances across the membrane can be either passive, occurring without the input of cellular energy, or active, requiring the cell to expend energy in transporting it. The membrane also maintains the cell potential. The cell membrane thus works as a selective filter that allows only certain things to come inside or go outside the cell.
