- Legumes
- require less fertilizers than other plants because they have bacteria in them that allow them to fertilize themselves
- germ theory
- the theory that infectious or contagious disease is caused by microbes (germs)
- Mycelium/ hyphae
- the threadlike filaments that comprise a fungus
- latin binomial
- a two word latin name, part of a system that names all living organisms and originated with Carolus Linnaeus
- xylem
- conduct minerals and water upwards
- Karyogamy
- Dikaryotic cell containing 2 compatible, haploid nuclei: NUCLEI FUSE
- mitosis
- nuclear division in which the chromosome number remains the same
- Pathogen
- an entity that causes disease
- Arable Soil
- valuable resource because: water erosion, plowing fields, flooding...unless we are putting the organic matter back in to the soil we are loosing top soil
- Eastern Hemisphere
- onion, citrus, cucumber, coffee
- Robert Koch
- German microbiologist that proved pathogenicity (Koch's Postulates)
- CO 2 is rising
- less photosynthesis, burning fossil fuels
- Plasmogamy
- Haploid Nuclei: join in the same cell
- Disease Triangle
- a memory aid that lists the three important components necessary for disease: susceptible plant, virulent pathogen, an favorable enviroment
- heterotroph
- depend on others for food (all fungi)
- dicot
- two seed leaves
- Fusarium spores
- macroconidia- infect the roots; microconidia move through the xylem and infect the inside; chlamydospores- helps the pathogen survive a long time during adverse conditions
- Monocot
- one seed leaf
- Meiosis
- reduction division and genetic recombination to form haploid nuclei
- autotroph
- make their own food through photosynthesis and chemosynthesis (green plants)
- Parasite
- an organism that loves on another organism and gets its food from that organism
- vegetative propagation
- asexual reproduction; in plants, the use of cuttings, bulbs, tubers and other vegetative plant parts to grow new plants
- ozone layer
- propellants that used to be in spray cans damage ______?
- Anton deBarry
- German botanist that proved plant disease was caused by pathogens
- Spore
- a reproductive body of fungi and lower plants
- Carolus Linnaeus
- Swedish naturalist that created a system for naming organisms
- Koch's postulate
- (proof of pathogenicity) the procedure used to prove the pathogenicity of an organism
- Global warming
- caused by green house gases that cause heat
- sexual reproduction
- a significant source of genetic variation for organisms
- Bacteria
- mitochondria, nucleus, cell wall
- Tuber
- an underground stem adapted for storage, typically produced at the end of a stolon
- prokaryote
- a cell lacking membrane bound organelles (bacterium)
- add nitrogen by
- fertilizers and planting legumes
- Plants
- mitochondria, nucleus, chloroplast, cell wall
- root hairs
- very small and increase the absorptive surface area of roots
- Animals
- mitochondria, nucleus, cell membrane
- stomata
- air exchange pores commonly found on the underside of leaves...plants release water through their sotmata
- root cap
- protects the apical meristem
- R.J. Petri
- invented the petri plate
- eukaryote
- an organism containing a membrane bound nucleus and other organelles (fungi, animals, and protists)
- meiosis
- process that creates new nuclei during cell division
- reduce level of CO 2
- photosynthesis
- Louis Pasteur
- French scientist that proved bacteria are not produced by spontaneous generation
- xylem
- water conducting tissue in plants
- Western Hemisphere
- cotton, maize, potato
- spontaneous generation
- the theory that microorganisms found in dead and decaying matter arose from the process of decay
