A scientist investigated the uptake of magnesium ions by the roots of young cereal plants. He made the following observations:
a. The rate of the uptake was increased by raising the temperature, so long as it did not exceed 40 degrees Celsius.
b. Uptake stopped if the roots were treated with cyanide, an ion that prevents respiration.
c. Ions were taken up even if they were present at a lower concentration in the solution around the roots than in the root cells themselves.
d. If ion uptake continued for some time, the concentration of sugars in the root cells decreased.
Question: What conclusions can be drawn from each of these observations?

a - the rate of uptake increased by increasing the temperature because when temperature is increased then the water evaporation is also increased which increases suction pull .
b - as suction pull is present till the time stomata open and close , cynide reaction stops respiration which stopped the opening of stomata , thus reduction in suction pull prevented the uptake of magnesium.
c - ions are taken by the process of diffusion , as there are less ions in roots them self , so ions travel from higher to lower concentration .
d - ion uptake continued , the salt content in ions is high , so the sugar content decreased
