Meristem Guías de estudio, Notas de estudios & Resúmenes

Agonist - Competitive inhibition, binds to active site and causes a signal response in receptive tissue. Antagonist (blocker) - Competitive inhibitor, binds to active site so signal molecules cannot bind but causes no response in receptive tissue, can bind and release eventually. Apply your understanding of channels and synapses to predict how various neurotoxins affect nervous function. - Neurotoxins block receptor proteins on the post-synaptic neuron. Example: tetrodotoxin form Fugu fish...

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...

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 terminal buds to inhibit the growth of lateral buds is call...

USABO 2024 Mass Deck Latest Update 100% Correct 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 i...
