Propagation and Plant Ecology

                                                                   

I.             Types of propagation

                A.            Sexual (seed)

                B.            Asexual (vegetative)

II.            Reasons for vegetative propagation

                A.            Generate clones from superior plants

                B.            Maintain genotypes used in synthetic varieties

                C.            Propagate varieties which are poor seed producers

                D.            Propagate genotypes with unusual chromosomes or that demonstrate sterility

III.          Tissues for asexual propagation

                A.            Stolons

                B.            Rhizomes

                C.            Crowns (dividing)

                D.            Stem cuttings

                E.            Leaves - tissue culture

IV.          Levels of biological organization

                A.            Subatomic particles - electron, proton, neutron

                B.            Atom - smallest unit of an element

                C.            Molecule - two or more atoms

                D.            Protein - a large molecule

                E.            Organelle - stuff inside the cell

                F.            Cell - smallest living unit

                G.            Tissue - group of specialized cells

                H.            Organ - one or more types of tissues

                I.             Organ system - two or more organs

                J.             Multicellular organism - an individual

                K.            Population - group of same species that can potentially interbreed

                L.            Community - populations of all species that occupy a habitat

                M.           Ecosystem - a community and its physical surroundings

                N.            Biome - an ecosystem occupying an extensive geographical area

                O.            Biosphere - that part of the earth occupied by living organisms

V.            Biomes of earth

                A.            Tundra - cold, dry, treeless plains (Wyoming, Alaska)

                B.            Taiga (also coniferous forest) - pine trees (Canada - USA border)

                C.            Deciduous Forest -  deciduous trees (Eastern and East of Oklahoma)

                D.            Tropical Rain Forest - lots of vegetation (Florida)

                E.            Savanna and Prairie - grasslands (Western and West of Oklahoma)

                F.            Desert - evaporation exceeds rainfall (Arizona)

VI.          Ecosystems and pollution
