Question
Regulation of germination Regulation of Physiological ProcessesExperiment (Starch-agar plates, GA, ABA, and glucose pr sucrose) Qs are related to theGA and Amylase lab *How does the concentration of a hormoneaffect the physiological response and the presence of one hormone block alter the action ofanother? *Does the concentration of sugaravailable to the embryo alter the hormone response andthe embryo itself have a hormone responsethat is different from the endosperm? *Does salt or other stress activate theABA repose or Ca2+ incvolved in the reponse of theseed to ABA? Only thing I know is that GA promotes amylase production inthe plant's seed. Even short answers will be apprecitaed andrated.

Therelative supply of energy and elements available to organisms inthe environment has strong effects on theirphysiology, which, in turn, can alter important ecologicalprocesses. Here we consider how resource imbalancesaffect three basic physiological processescommon to all organisms: elemental uptake, incorporation, andrelease. We review recent research thataddresses these core issues (uptake, incorporation, andrelease) as they relate to elemental homeostasis inautotrophs and heterotrophs. Our review showsthe importance that organism elemental homeostasis plays indetermining the types of physiologicalprocesses used to acquire, assemble, store, and releasebiogenic elements, which are found in widely varyingratios in the environment. Future researchshould examine the degree to which organisms assess their internalnutritional composition and that of theirfood sources within a multiple elemental and biochemicalcontext. Also, scientists should explore if and howthe stoichiometry of cellular and molecularresponses underlying nutrient (elemental and biochemical)acquisition, incorporation, and releasedepends on the nutritional composition of food resources.These types of queries will further improve ourunderstanding of the physiological processingof primary elements involved in growth, reproduction, andmaintenance of organisms.
