- Ethylene Production Place
- Produced in Ripening fruits
- Gibberelin History
- Rice disease- 1809 foolish seedling disease. 1898 , japan discovered that a fungus called gibberella fy'u koroi. 1925 kurosawa grew fungus in a flask then boiled it to create a liquid solution of gibereela to purposely infect plants. 1930's isolate active ingrediant. Looked a lot like a steroid.
- Gravitropism
- Gravity affects growth patterns
- Modified Leaves- Window Leaves
- Windows don't have photosynthetic parts, it just allows light into. Bottom of the plan which is underground is photosynthetic. This type of plant allows for less water evaporation.
- Mobile
- Nutrients go to new lead and old leaf shows symptoms fiirst
- Fruit Growth
- Long grapes are induced by the hormone treatment by spraying the fruit with gibberelin
- Modified Leaves - Succulent
- Function: Storage of water in dry environments. Ex: Cactus
- Lack of Ca
- Wrinkling (not enough cell support)
- Bladderwart
- A very small green gas filled structure that floats in water. Attracts aquatic insects that triggers open when bumped into and water rushes into the empty vessel bringing the insect with it.
- Apical Dominance
- Normal state - make plant taller - repress lateral bud growth. Apical root formation on callus, only have roots . Stems and leaves require another hormone.
- Lack of agnesium
- Plant turns yellow (chlorosis)
- Abscisic Acid History
- 1949- found out that dormant buds contained a unique chemical- they called it dormin. 1965- looking for what caused leaf abscission, and called it abscisin.
- Cytokinin Production Place
- Produced in roots (mainly), also produced in seeds and fruits
- Ethylene Activites
- Fruit ripening, wound repair, leaf abscission
- Gibberelin Activites
- Internode elongation, stimulate seed germination, fruit growth, can stimulate flowering,
- Tropisms
- Tendency to grow because of a certain element in the environment
- Micro-nutrients
- Na, Fe, Mn Zn, Cu, Mo, B, Cl. Never feel badly, montana zn's creates crying men
- Auxin Activities
- Stimulate cell elongation, stimulate root growth, apical dominance, fruit formation, and acidification of cell wall
- Cytokinin Activities
- Cell division, stimulate lateral bud growth (in tissue culture), delays seed senescence
- Nutrient Cycling
- Things going in and out of liviing things.
- Lack of B
- Stunted growth
- Abscisic Acid Activities
- Fruit drop( relase of fruit from plant), leaf drop, dormancy (biggest activity, stop being active, quietly waits for winter to be over, makes bud scales), and guard cell closing(under drought stress stomata closes)
- Plant Litter
- Whaterver was in plant leaves gets released back into the soil. Bacteria of fungi decomposes leaves into organic humus
- Acidification of cell wall
- Expansins are enzymes that losen the cell wall. Auxins stimulate expansins.
- Brassinosteroids
- Helps in membreanes, tissue production, and reproduction
- Immoblile
- Nutritens stay in old leaf, and new leaf shows symptoms fiirst
- Sundew
- Native. Has long sticky hairs that insects get stuck too. The whole plant is only a few inches tall.
- Gibberelin Production Places
- Produced in soy bean plant seeds (phaseous yulgaris). Produced in embryo, apices of root, the shoot, and legumes.
- Symbiotic fungi
- Either on the outside or inside of the root, helping with nutrient uptake.
- Hydrophonics
- Way to grow plants without water. Grown in a liquid. Soil is to uncontrollable in an experiment.
- Wound Repair
- Forms corkey subernized layers that scab over wound sites
- Heliotropism
- Tendency to move towards the sun. Ex sunflowers.
- Hormone
- A signal Molecule that is produced in small quantities in one part of the organism and transported to another place in the organism.
- Stimulate flowering-gibbereling
- Stimulates with light which naturally stimulates gibbereling or by using gibberelin. Gibberelin effects the transcription gene.
- Stimulate Seed Germination
- Barley seeds will germinate on their own, when they do the embryo releases gibberelin to stimulate starch degrading enzymes=possibility of growth
- Leaf Abscission
- Gets tree ready for winter as well. Wall off pediole from the tree so that sap does not leak out when leaves fall off.
- Pitcher Plant
- A plant that secretes nectar to attract insects. If the insect comes to close to the inner edge it falls into the trap and is unable to crawl out because of downward facing hairs.
- Lack of Fe
- Interveintal chlorosis (Space between veins are yellow)
- Venus Fly Trap
- Also known as a snap trap, lives naturally in north carolina swamps and consumes insects for nitrogen.
- Macro-nutrients
- C, H, O, N, S, P, Mg, K, Ca. Please Have Some More Nuts On Crazy Caramel Kreamicle.
- Modified Leaves - Bracts
- Showey leaves that look and act like flower structures.
- Abscisic Acid Production Places
- Plants produced in base of ovary (flower), buds, and leaves.
- Auxin History
- Went. Took an oat coleoptile and cut off the top part of the oat and put it in on agar so the biolchemistry was collected in the agar dish. He then put the agar on the tip of the oat and it curved towards the light.
- Cactus
- Have modified leaves known as spines to keep animal from chewin on them
- Modified Leaves - Reproductive Leaves
- Plantlets grown on margin of plant leaves that break off by fragmentation. A Sexual Reproduction. Ex: Walking fern
- Oligossaccharines
- Carbohydrate molecule from plant cell walls. Turn into signal molecules when plant wall is being destroyed. Only for plant defense. Stimulate plant cell walls to harden.
- Modified Leaves - Carniverous Leaves
- Plants that gain their nutrients from insects. Live in nutrient poor environments. Swamps and Bogs.
- Inorganic Soil Sizes
- Gravel, San, Silt, Clay.
- Phototropism
- Tendnecy to grow towards light
- Thigmostropism
- Tendency to grow around objects that they bump into. Vines.
- Optimal Soil
- Loam- Mixture of 40% sand, 40% silt, and 20% clay.
- Cytokinin History
- Skoog and Miller- tissue culture. Worked with a carrot callus wanted to regenerate an entire carrot, discovered that herring sperm made leaves grow. Only works with partially broken down sperm. When adenine breaks down kinetine is produced which produces growth. Adenine nucleotides can produce this molecule as well as maise.
- Lack of N
- Stunted growth and chlorosis
- Ethylene History
- 1800's st. petersburg russia they had gas street lamps and the trees by the lamps would drop their leaves and develop fruit before the rest of the trees would. 1901 Dimitryi Neljubov tested gas affect by inhibiting gravitropism, took pea plants in a tube and blew ethylene through it. Plant grew straight out instead of curving.
