3: Theador schwann German physiologist who served as an assistant to Johannes Muller. He discovered the digestive enzyme pepsin in 1836. He showed that yeast were tiny plant-like organisms, and suggested that fermentation was a biological process. Schwann was a master microscopist who examined animal tissue, specifically working on notochord development in tadpoles. Microscopic researches on the Conformity in Structure and Growth Between Animals and Plants," 1839), he recognized nuclear structures similar to what Schleiden had observed in plants. In 1839, he extended Schleiden's cell theory to animals, stating that all living things are composed of cells. He believed that new cells form principally outside pre-existing cells, and wanted to draw an analogy to crystal formation.

5: Robert Hooke Relatively little is known about Robert Hooke's life. He was born on July 18, 1635, at Freshwater, on the Isle of Wight, the son of a churchman. He was apparently largely educated at home by his father, although he also served an apprenticeship to an artist. He was able to enter Westminster School at the age of thirteen, and from there went to Oxford, where some of the best scientists in England were working at the time. Hooke impressed them with his skills at designing experiments and building equipment, and soon became an assistant to the chemist Robert Boyle. In 1662 Hooke was named Curator of Experiments of the newly formed Royal Society of London -- meaning that he was responsible for demonstrating new experiments at the Society's weekly meetings. He later became Gresham Professor of Geometry at Gresham College, London, where he had a set of rooms and where he lived for the rest of his life. His health deteriorated over the last decade of his life, although one of his biographers wrote that "He was of an active, restless, indefatigable Genius even almost to the last." He died in London on March 3, 1703. Hooke's reputation in the history of biology largely rests on his book Micrographia, published in 1665.

7: Matthias Jakob Schleiden | Matthias Schneider studied laws in Heidelberg, he recevied his PhD in 1826 and became a lawyer in his hometown of hamburg. this work was unsatifactory for him but he still became very sucessful. schneider was in 1835 after the berlin, where his uncle j. Horkel professor and mainly dealt with plants, but also with plants physiology. here he got to know Richard brown. both researchers suggested to him to deal with the issues of plant embryolgy & cell formation. it created several botanical paera on these topics. a recurrents depression phase, he overcame with relatives in Wernigerode in the Harz mountains.

9: Virchow studied medicine and chemistry in bleien at the pu\russin military academy from 1839 to 1843 on a scolership. when he gratuaated in 1843, he went to serve as robert florien's assistants at the charity hospital. virchow's most known scientific contributio is his cell's theroy, which built on the work of theodor schwann. he is cited as the first to recongnize leukemia cells. he was one of the first to accept the work of robert remake who ahowed that the orgins of the cellls where divdied into cells. he believed that maggots litally come from an egg. he says that the only source of a living cell was another living cell. | Rudolf Virchow

11: CELL THEORY | All life forms are made from one or more cells. Cells only arise from pre-existing cells. The cell is the smallest form of life.

13: Cell membrane While the plant cell has a rigid cell wall, an animal cell membrane is a flexible lipid bilayer. The lipid molecules (mostly phospholipids) that make up the membrane have a polar, hydrophilic head and two hydrophobic hydrocarbon tails. When the lipids are immersed in an aqueous solution the lipids spontaneously bury the tails together and leave the hydrophilic heads exposed. Thus this is a handy membrane to use, because it can automatically fix itself when torn. There are three different major classes of lipid molecules - phospholipids, cholesterol, and glycolipids. Different membranes have different ratios of the three lipids. What makes the membrane truly special is the presence of different proteins on the surface that are used for various functions such as cell surface receptors, enzymes, surface antigens, and transporters. Many of the membrane-associated proteins have hydrophilic and hydrophobic regions. The hydrophilic regions are used to help anchor the protein inside of the cell membrane. Some proteins extend across the lipid bilayer, others cross the bilayer several times

15: Homeostasis the tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedbackcontrols, so as to stabilize health and functioning, regardless of the outside changing conditions The ability of the body or a cell to seek and maintain a condition of equilibrium or stability within itsinternal environment when dealing with external changes

16: Prokaryotic cells Cells that lack a membrane-bound nucleus are called prokaryotes (from the Greek meaning before nuclei). These cells have few internal structures that are distinguishable under a microscope. Cells in the monera kingdom such as bacteria and cyanobacteria (also known as blue-green algae) are prokaryotes.

17: Eukaryotic cells Eukaryotic cells also contain many internal membrane-bound structures called organelles. These organelles such as the mitochondrion or chloroplast serve to perform metabolic functions and energy conversion. Other organelles like intracellular filaments provide structural support and cellular motility

18: plants vs. plants have chloroplast, chloroplast uses energy from the sun to make food for the cell central vacuole stores food water and wast products cytoplasm is a liquidly substance that is in between the cell membrane and the nucleus

19: Animal The golgi apparatus modifies sorts and packages poteins and other materials for the endoplasmic retculum the peroxisoe beais down toxins in the cell mitocondria makes enegy for the cell with the food its been given

20: Ten cell structure 1. nucleus:contains the DNA an is a brain of the cell 2. Rough ER: is in both animal and plant cell this transports proteins that are made form ribosomes. 3. Mitochondria:makes and stores energy for the cell

21: 4. Ribosomes: help make proteins and is found in a plant cell. 5.Chloroplast: uses the energy from the sun to make food for a cell this is found in plant cells. 6.cell wall: protects the cell and keeps the plant cell stiff and strait

22: 7. Central vaccuole: stores food, water, waste products and other materials this is found in plants cells 8. Golgi apparatus: modify sort and package proteins and other materials from the endoplasmic retuculum this is found in an animal cell

23: 9. Lysosoes: in animal cells they break up waste materials and debris 10.peoxisome: breaks down toxins in the cell this is found in a animal cell
