Sucrose is an osmotically active solute in guard cells, One implication of these osmoregulatory features is that stomatal opening & closing is associated with which of the following given statements?

#Unit 6. System Physiology – Plant
  1. Closing of stomata is associated with a decrease in sucrose content primarily and then opening of stomata associated with K+ uptake
  2. opening of stomata is primarily associated with K+ uptake, and closing of stomata is associated with a decrease in sucrose content
  3. opening of stomata is primarily associated with a decrease in sucrose content and closing of stomata is associated with K+ uptake
  4. opening of stomata is primarily associated with ions uptake and closing of stomata is associated with a increase in sucrose content

Following statements regarding to the classes of genes that regulate floral development:

A.  Floral organ identity genes directly control floral identity. The proteins encoded by these genes are transcription factors that likely control the expression of other genes whose products are involved in the formation and/or function of floral organs.

B.  Cadastral genes act as spatial regulators of the floral organ identity genes by setting boundaries for their expression.

C.   Meristem identity genes are necessary for the initial induction of the organ identity genes. These genes are the positive regulators of floral organ identity.

D.  Cadastral genes act as negative regulators of the floral organ identity genes by inhibits their expression.

E.   Meristem identity genes are the negative regulators of floral organ identity genes.

Which of the following statements is correct regarding the stereochemistry of Thr, Ile 
1. Thr, Ile is special case because of two chiral center exist in L-Ile in 2R,3S and L-Thr in 2R,3S configuration 
2. Thr, Ile is special case because of two chiral center exist in D-Ile in 2R,3S and D-Thr in 2R,3S configuration 
3. Thr, Ile is special case because of two chiral center exist in L–Ile in 2S,3R and L–Thr in 2S,3R
