Arborist Certification Study Guide with Complete Solutions Meristem Correct Answer-Sites of rapid cell division in the shoot tips, root tips, and cambium. Apical meristem Correct Answer-Meristems located at the end of the shoot are called primary, or _________ meristems Scales Correct Answer-Buds are covered by _____________ that leave permanent scars on the twig when the buds break dormancy. These scars can be useful in tree ID. Apical dominance Correct Answer-The tendency for termina...

what are pneumatophores good for? - oxygen uptake what macronutrient helps with plant growth? - nitrogen deficiency of which mineral causes purplish coloration of the leaves? - phosphorus why can it be difficult for a plant to get access to cations in the soil? - clay is often negatively charged and tightly binds to cations which can make it difficult for the plant to take these ions up what protein causes a reddish color in plant tissue? - leghemoglobin what is leghemoglobin needed for in...

The Primary role of Fungi Decomposers- they break things down Modes of Nutrition in Fungi Heterotrophs with extracellular digestion Exoenzymes Fungi Release these enzymes outside of the cell wall. Break down complex molecules into smaller organic molecules which can be absorbed. Extracellular Digestion The release of exoenzymes out side of the cell wall, followed by the absorption of nutrients.. Saprobes Fungi that feed on non-living/dead organisms Symbionts Fungus that lives with another...

WSU Biology 106 Exam 2 >> Questions and Answers Graded A++ Fungi heterotrophs that feed by absorption Heterotrophs absorb nutrients from outside the body Roles of fungi decomposers, parasites, mutualists (symbiotic and microrizzae), early land colonizers What do fungi use to break complex molecules? Enzymes Chitin made of cellulose, make up the cell walls of fungi Hyphae continuous strands above/below ground, generate spores, colonizes soil Fungi life cycle Mycellum a ...

charophytes - (aquatic) green algae land plants evolved from 3 key traits land plants share with charophytes - 1. rings of cellulose-synthesizing proteins embedded in plasma membrane 2. formation of a phragmoplast (helps form cell wall) 3. structure of flagellated sperm (not all will have this) adaptations enabling plants' move to land: why? - 1. CO2 2. sunlight 3. soil- nutrients 4. fewer predators/pathogens (never been seen before) adaptations enabling plants' move to land: pro...

Mycorrhizae : Symbiotic organisms (aka symbionts) with plants that live on their roots, helping the plant gain nutrients Nerve net : A nervous system that moves neural signals in all directions from the stimuli, found in invertebrates like hydra Malpighian tubules : Tubes in an insect that help with osmoregulation and excretion; they move waste into the main gut for removal. "Kidneys" of arthropods, they absorb ammonium and convert it into uric acid, then into the main gut for rem...

fruit development ~ what happens when auxin is applied to the stigma of a unpollinated flower ? Provide food to animals eating the fruit even if pollination isn't successful à Maintaining dispersers alive for seeds that do develop ~ Advantage of having some parthenocarpic fruits for the plant? when there are more than 2 sets of chromosomes ~ what is polyploid Autopolyploidy ~ polyploid product of intraspecific crossing (2 parent cells from the same species) gibberellin ~ pl...

3 mechanisms for prokaryot genetic recombination - 1.)Transformation 2.)Conjugation 3.)Transduction Absolute dating - -Radioactive isotopes decay over regular annual time periods (half-lives) -C14 5,700 yrs - radioactive isotopes vs stable isotopes -stable isotopes stay the same after the organism dies Alexander Fleming - -Discovered Penicillin -microbe v. microbe interaction -Capitalized on mistake in the lab, left plate out and fungus grew on it Algae - -Protist -plant like; photoau...
