Plants and people unit 1 Study guide BSC1005 Biology What are characteristics of green plants? plants are green because they have chlorophyll to trap sunlight for photosynthesis, rigid cell wall, and reproduce (flowers) organisms are named based on? binomial system (genus,species) how are organisms classified? based on their evolutionary/genetic relatedness what are the classified kingdoms in order? Kingdom, phylum, class, order, family, genus, species What are the five groups organism are grouped in? Bacteria, animal, fungi, protists, plants Define cell All living things are composed of it and each cell is surrounded by a cell membrane, has a cytoplasm, and a nucleus Difference between animal and plant cell? plant cell has a cell wall on the outside of the cell membrane and chloroplast (where photosynthesis takes place) in the cytoplasm what was the first drug synthesized and where did it come from aspirin and from the bark on willow trees what was the first drug to be chemically isolated? morphine why do plants produce chemicals? to defend against disease causing organisms and herbivores, and they attract pollinators how are plants becoming more genetically modified? by gene cloning techniques to be more resistant to herbicides and insects. more than 50% of the corn, soybean, and cotton crops are genetically modified in the u.s state problems with modern agriculture: fertilizer and pesticide solution of rivers and lakes, top soil loss due to repeated plowing, growing shortages of water, and genetic uniformity, which facilitates plant diseases nitrate and phosphate with modern agriculture: nitrate for fertilizer is synthesized and phosphates for fertilizer are mined describe modern agriculture: crop rotation is not practiced; instead synthetic fertilizer is applied to field to replace nutrients that were used up by previous year’s crop nitrate cycle bacteria in the soil - convert nitrogen gas in the atmosphere into nitrate- that plants then use nitrate to build proteins- animals get nitrate by eating plants- then poop them out and they return to the soil what two mineral nutrients are more readily lost from the soil nitrate and phosphates early agriculture innovations were? Irrigation, development of the plow, and the three crop rotation system, which replaces soil nutrients needed by plants What is significant about the earliest crop domestication? Involved the unintentional selection for loss of natural seed dispersal, reduce seed coat thickness, and larger seed Where did the most important crops come from? Rice- asia Corn and beans- northern south America Wheat- middle east Potatoes- andes south America Bran, gymnosperm,germ Bran- seed coat of cereal grain Germ- embryo Endosperm- carbs What accounts for 75% of calories: corn wheat rice potatoes why are conifers so important? they produce paper and wood alternations of generation: when spore forming version of plant makes spores, the spores grow into plants that make gametes (egg and sperm) and fertilization results in more plants of the spore forming type what were the earliest land plants? Mosses Describe green algae: Are in green plant kingdom and are the progenitors of land plants Red and brown algae describe: they are multicellular photosynthetic organisms living in the ocean, are not classified as plants they are in protista, and are harvested commercially for their cell wall materials, which are used for everything from paint to cosmetics to beer and toothpaste define phytoplankton: photosynthetic plankton function of the fruit? Dispersal of seeds What do animal pollinated flowers produce? Attractants and rewards Difference between animal and plant cell Plant cell has a cell wall and the cytoplasm (makes photosynthesis) What was first organism to evolve: Bacteria What are the kingdoms? Kingdom, phylum, class, order, family, genus, species What are the characteristics of green plants? Plants are green because they have chlorophyll to trap sunlight for photosynthesis, rigid cell wall, and reproduce (flowers)
