  • The mineral concentration within the soil is very low, therefore, it is dissolved in water and move around the soil in solution.
  • Plants absorb the minerals from the soil with the help of root hairs.
  • The minerals are absorbed in the form of ions.
  • The mineral absorption by plant roots take place in two phases-
1) Intial phase- The rapid uptake of ions into outer free spaces of the plant cells (apoplast).
  • The free spaces include the intercellular spaces and the cell wall.
  • The entry of ions into the outer space is passive absorption, i.e no energy is required.
2) Metabolic phase- The mineral ions diffuse into the cell cytoplasm and vacuoles (symplast).
  • The entry of ions into the cell requires energy, therefore, is called active absorption.

Is the picture correcr about stretch activated ion channels and calcium ion fatigue? So far the research Iv'e read really only talks about an influx of sodium ions causing a decrease in the release of calcium ions which causes fatigue. Is influx of sodium ions and influx of cacium ions two different types of fatigue? if so when does each occur? Please give an in depth response Calcium ion-related fatigue mechanisms are essential to understand because[A] they reduce the mechanical tension produced and experienced by muscle fibers during a strength training workout (and therefore reduce the size of the stimulus for hypertrophy) and because [B] they are long-lasting and therefore increase the duration of the post- workout recovery period.Calcium ion-related fatigue mechanisms occur largely due to the accumulation of calcium ions inside the cytoplasm (subseguent to muscle activation which then trigger many effects Calcium ion-related fatigue is increased when training:[1] with higher volumes and with lighter loads(because of the longer time for which the working muscle fibers are activated and therefore sending calcium ions into the cytoplasm);[2] closer to muscular failure (because of the recruitment of more higher threshold motor units and the activation of more fast twitch fibers);and[3]with long maximum muscle lengths,full ranges of motion,and eccentric contractions(because stretching activated muscle fibers opens stretch-activated ion channels which allows extracellular calcium ions to enter the cytoplasm).Calcium ion-related fatigue can therefore be reduced by training with lower volumes,heavier loads,further from muscular failure.with concentric-only contractions.and to either short maximum muscle lengths or with partial ranges of motion.
