11416 1 Key Box Abbreviations Know for test EX Example besides definitions quotsppquot species 2 Definition 0 Economic Botany 0 Ethnobotany someone who studies plants and how people utilize plants Economic Importance of Plants a The state of plants determine what happens to prices Supply and Demand b Ex South America is known for its coffee plantations One winter South America experienced a severe freeze causing many of the plants to die The following week coffee prices soared up due to the fear of selling out of coffee with no new shipments coming in Plants support all life forms a Ex microscopic plants are intrinsic for environmental life ecosystem b Not only necessary for the environment but also for humans we breath them in every day Civilization was made possible by the domestication of a few species of plants a 254000 spp of plants i Out of the 254000 we only use about 3000 spp ii Out of those 3000 we have domesticated changed for our use 200 iii Out of all of the above humans are only dependent on 15 plants b Domestication Ex In Mexico a man made corn out of a wild plant over a few decades i Difference between plants and animals Animals become domesticated over a very long period of time centuries Plants take only a few years or decades ii Domesticated plants ex wheat rice corn etc I Word origin Titles 5 Ecology a plant wherever it is located modifies that environment for other organisms around it 6 There are many variations of plants a 1st there was only the 2 kingdom system Plants and Animals Plant Animals GREEN Chlorophyll the pigment that gives 1 NO Chlorophyll the green COlor to plants 2 Heterotrophic have to find food consume Autotrophic makes own food organic material Non mobile Stationary 3 Highly mobile a There are visible rapid movement in 4 Usually have a nervous System some caused by Water ex bean 5 No cell wall Animals and humans do not have cell No nervous system Cell Wall composed of cellulose humans cannot digest plant s rigid cell walls 6 Cell division only occurs in certain regions of plants called meristems a plant venus fly trap walls anywhere in our bodies not a single cell has a cell wall our cells are pliable We have cell membrane NOT cell wall No meristematic cells cell division throughout the entire being cannot clone animals the same way you can clone plants completely different Meristems this legion of cells are not decided on what they what to docell division cell reproduction etc Ex cut off leaf of plant the meristems in the leaf changes its decision and grows a clone plant 0 Many organisms do not fall on either kingdom and some fall in both in regards to the different characteristics 0 Therefore there are now 5 kingdoms 1 Monera 0 Most bacteria are classified under Monera o Primitive cell type prokaryotic no nucleus 0 reproduces asexually 2 Protista N0t 0 Single cell organism all cells appear and act identically Multl cellular o 3 major groups of Protista types 0 Protozoa o Algae o Slime molds 3 Fu gi 0 Basic fungi Complex ce 0 Ex Yeast IS claSSIerd as a mold type Eukaryotic 439 Plant 0 Autotrophic makes food 5 Animal Multicellular o Heterotrophic finds food o Kingdoms separated on a cellular level Note the word species does not exist without an quot5 Abbreviations sp one species spp more than one species 0 Practice examples of scientific names 1753 Genus Species Carl Linneaus Scientist decided that all organisms Homo sapiens should have a two part name binomial Arachis hypogea Spiper underjbelow refers to a peanut plants its own fruits and earth and seeds 3 Mimus

Semperviridus green Always 1 Monera Kingdom a Cyanobacteria i Among the smallest things on the planet but also one of the most important ii Often found in roots 1 Ex Fabaceae a Every Fabaceae has cyanobacteria in its roots this is the reason why beans are so full of protein The cyanobacteria in the plant produces high levels of N2 and NH4 The levels are so high the plant cannot consume all the nitrogen and disperses it into the soil fertilizing it Thus creating a reason to rotate fields to keep them fertilized 2 Protista Kingdom a It is at the bottom of the food chain but it is necessary otherwise the food chain would collapse i Both good and bad ii Bad ex water in Mexico can really screw with one s system 1 Two main types a Algae is photosynthetic b Protogoa is autotrophic 3 Fungi Kingdom a Most alien like Ex crazy ants effected by fungi b Heterotrophic c No Chlorophyll d Filamentous the individual filaments that make up fungi i Individual specs hyphae ii Whole group of filaments mycelium iii Ex Moldy bread 1 The whole mold spot mycelium 2 Individual spots of mold under a microscope hyphae e Contains chitin f Fungi are either 1 Saprophytic feeds off of deadorganic material 2 Parasitic lives off of something a Ex ring worm fleas etc 3 Pathogenic causes a disease g So why do we like fungi Popular fungi i Yeast consumes other organisms in order to create other by products after its consumption ii Penicillium Alexander Fleming tried to cultivate bacteria in a petrie dish mold kept killing the bacteria Penicillium is antibacterial and grows on rotting fruit iii Cheeses Wine Beer incorporate all different types of fungi h Not all fungi is good i In King Tutt s tomb practically all of the first explorers died within a year of the expedition 2 l expedition in fear of the new quotmummy s curse those explorers were more careful and found deadly fungus called quotAspengillusquot Note If you have a fungus and you treat it as if it were a bacteria that fungus could and probably will grow more rapidly Categories for Classification 0 Top tier of classification with 5 kingdoms 0 Ex Vertebrate 0 Ex Mammalia mammals 0 Ex Rodentia Rodents 0 Ex Carnivora
