BIOL 1110 Lecture Notes - Lecture 7: Exponential Growth, Biocoenosis, Sulfur
Document Summary
Biol 1110: lecture notes 7-8: life is organized. Organizational composition of life will confer structure and function. Matter anything that has mass and takes up space. 3 states: solid liquid gas: matter is composed of elements, elements pure substances that cannot be broken down by normal chemical processes, oxygen (o), hydrogen (h), nitrogen (n), and carbon(c) A number of elements cycle on small and large scales. Phosphorus (p), nitrogen (n), carbon (c), sulfur (s) *cycle starts over: we categorize elements into the periodic table. 25 elements are essential to living organisms: essential elements=nutrients. Nutrients elements an organism needs to survive, grow, and reproduce: energetics: Carbohydrates: carbon (c), hydrogen (h), oxygen (o: morphogenesis the origin/development of morphology. Important: n, p, ca (calcium), c, etc. : metabolic support. Important: cu (copper), fe (iron), i (iodine), vitamins, h2o: break essential nutrients into 2 categories based on amount needed, macronutrients substances required in relatively large amounts.
