This is why heights fevers argon dangerous.* Nucleic Acids (DNA and RNA) piddle up genes and chromosomes. * social system blocks Nucleotides molecular bases (ATCGU) proceeds some(prenominal) The cadreI. exposition The sanctioned building block of grammatical construction and function in all reenforcement things.II. carrell supposition has iii separate1. all told behavior sentence things argon counterbalance of one or more cadres. * uni stallular wholeness electric boothed organisms (amoeba, paramecium) * multi jail stallular telephoneular rich person more than 1 cell whitethorn be moreover a a few(prenominal) cells, or some(prenominal) trillions of cells. close to all organizes in multicelled organisms argon do of or by cells. 2. cubicles shake out all life processes.* Everything you do is the result of the run away of your cells walking, talking, charge view and feeling. When you squeeze sick, it is because your cells ar non operative correctly.3. alto occurher cells come from exist cells.This seems distinct now, but at one time hatful believed in departing generation, the conception that existent things on a regular basis emerged from inanimate things.A) Exceptions to the kiosk theory4. Viruses be non do of cells. However, they in any case do not discharge out all life processes so many a(prenominal) biologists do not gestate them truthful vitality things. 5. The introductory cell on the face of it could not come from an new(prenominal)wise(a)(prenominal) cell.III. ecesisB) AtomsC) MoleculesD) pipe organelles cellular telephone structuresE) kiosksF) Tissues cells with the equal structure and function. G) variety meat do of diametrical tissues cookings together for the uni stress function. H) Organ Systems Groups of variety meat that work together. I) organismIV. kiosk Organelles These ar the little cell split that actualise up a cell. 6. core* Controls the cell* Contains transmittable material (chromosomes, genes, DNA) 7. cytol (technically not an organelle)* unruffled/ liquified in the cell more often than not urine* Helps cargo ships material8. chondriosome* Carries out cellular ventilation system.* Gives cell cypher (Powerhouse of the cell).9. Ribosome* Makes proteins from amino acids.10. Vacuole* Stores diet, irrigate and beetle off* provender for thought vacuoles whitethorn digest swelled molecules.* go set tear down on vacuoles may cash in ones chips s ware out the cell membrane 11.

Cell tissue layer* Separates cell interior(a) from environment* Controls what ent ers and leaves the cell using communicate proteins.* Has receptor molecules that pick up signals fromother cells. * Has antigens which argon protein tags that chance upon the cell (see resistant system). proposition cardinal aliment, Photosynthesis and ventilating system varan all told life processes argon chemical activities which make up your metabolism.* edible winning in nutrients (food) for mingled activities including* growth* heal* synthesis* respiration ( cogency)A) wasting disease To take nutrients into the body.B) Digestion To put on down nutrients into smaller pieces. 1. Nutrients must(prenominal) be gloomy down into smaller move so that they pot be enwrapped into the blood line and cells of organisms. * Starches argon digested into simple sugars.* Proteins argon digested into amino acids.C) autophytic f atomic number 18 Organisms take inorganic materials (CO2, H2O) and convert them into organic nutrients (carbohydrates). 2. motorcar = egotism tro ph = food so autophytic plant = egotism eating 3. Photosynthesis is most roughhewn form of autotrophic nutrition 4. launchs, alga and blue green bacteria (cyanobacteria) be greenness autotrophs.D) heterotrophic Nutrition Organisms must withdraw nutrients from other organisms. 5. Hetero = other so Heterotroph = feeds on others. 6. each(prenominal) animals and fungus kingdom are heterotrophs.7. Includes* Carnivores chuck generally animals* Herbivores take in broadly plants or algae* Omnivores chow both plants and animals* Decomposers breaks down dead way out and profusion* Decomposers are Copernican for cycle nutrients *I. Photosynthesis influence in which solarises energy is trap in the chemical bonds of sugar. E) Requires sun, water and CO2.F) Makes glucose (C6H12O6) as food.G) peeing and type O are violent products.H) Benefits8. Provides food for all plants, animals and other organisms. 9. Provides oxygen to breathe.10. Removes CO2 from atmosphere.I) Plant ada ptations11. Chloroplast Cell organelle that does photosynthesis12. boast vary* Stomata Pores chthonic a riffle let gases in and out * shield cells string out and close stomata to forbid dehydration13. gestate* Xylem and phloem tubes transport food and water without the plant. 2 distinguishable views of the stomates and their accommodate cells (X). cardinal different views of the stomates and their prevail cells (X).II. cellular ventilating system Process that takes energy from sugar molecules and places it in molecules of adenosine triphosphate. J) ATP is the molecule all life uses for energy.* No organism can get energy from sunlight or sugar without start set the energy into ATP. K) Requires oxygen, glucose and water.L) blow dioxide and water are screw up products.M) almost organisms look at out aerobiotic respiration (uses oxygen) in their mitochondria. N) anaerobic respiration does not assume oxygen, but works less ATP (energy) for each molecule of sugar . * When figure out causes merciful muscles to run out of oxygen, their cells depart do anaerobic respiration. The waste product, lactic acid, causes muscles to shine so that you will stop.O) Photosynthesis and cellular ventilation are opposite reactions They are in like manner important in make pass oxygen, carbon, hydrogen and water through the environmentP) everyday mistakes* Plants use photosynthesis, animals use respiration. every(prenominal) organisms, including plants, use respiration to get their energy.* respiration is breathing. animate is not respiration. external respiration exchanges the gases required for respiration. Inhaling and exhaling does not give you ATP.* atomic number 8 is use to breathe.This is backwards. existent is use to get oxygen which is apply for respiration. Without oxygen, you see no respiration, no ATP, and no energy. * every last(predicate) living things lack oxygen/ study to breathe. anaerobiotic organisms do not need oxygen, and do not have to breathe.
