BIOL 1201 : Exam 5
Document Summary
Control system in plants: types of plant hormones, examples of hormone function. Apical dominance, germination, attract mycorrhizal fungi to the root. Plant rhythms: some plant processes (flowering etc. ) follow a daily cycle suggesting plants have rhythms, how do plants keep track of time, ex. Given a bucket of water and 3 bowls design a machine to measure the passage of time. You do not have to use all of the equipment (clicker: measure passage of time by reduction of something, or accumulation of something. Auxin in stem elongation: apical meristem produces auxin, transported down the shoot (only) Two major systems: endocrine, hormones secreted into the blood stream, broadcasts the signal throughout a broad area (via bloodstream, nervous, neurotransmitters secreted into the synapse(junction) between neurons, sends the signal directly to a target cell (via neuron/s) Similarities: many hormones are neurotransmitters, some neurons secrete hormones, both systems involve cells communicating with other cells.
