Given below are some of the statements that regulate the sucrose loading mechanism;

A) The solute potential or, more likely, the turgor pressure of the sieve elements

B) Sucrose concentration in the apoplast

C) The available number of symporter protein molecules

Possible observation given on how to avoid regulation;

i) increase in sieve element turgor above a certain threshold would lead to a compensatory increase in loading

ii) High sucrose concentrations in the apoplast would increase phloem loading

iii) SUT1 transporter mRNA and protein have been lower after 15 hours of darkness than after a light treatment. These data suggest that the concentration of SUT1 transporter molecules could regulate loading

iv) Decrease in sieve element turgor below a certain threshold would lead to a compensatory increase in loading

v) The transporter mRNA and protein high in darkness than lower in the light treatment

Bioinformatics can be used to scan sequences for probable genes looking for start and stop sites for transcription and for translation, for probable splice sites, and for sequences known to be found in other known genes. Such sequences containing these elements are called

Mengel and Kirkby  have proposed that the essential elements be classified instead according to their biochemical role and physiological function, It shows such a classification, in which plant nutrients have been divided into some basic groups these are;

a.) The first group is nutrients that are part of carbon compounds

b.) The second group is important in energy storage reactions or in maintaining structural integrity

c.) The third group has important roles in reactions involving electron transfer or redox reaction

d.) The fourth group is present in plant tissue as either free ions or ions bound 

Which one of the following group represents CORRECT statements
