QUESTION 17 The accumulation of phosphorylated sugars in the cytoplasm will Increase the activity of certain key Calvin Cycle enzymes Promote export of phosphorylated sugars in the phloem Promote export of triose-P from the chloroplast Promote starch synthesis in the chloroplast Promote starch degradation in the chloroplast QUESTION 18 A tomato fruit growing on a vine will receive most of its nutrients and water from O The xylem Storage reserves such as seeds and tubers All regions of the plant more or less equally Its own photosynthetic capabilities O The mature leaves closest to itExplanation / Answer
Q 17)
Promote the synthesis of starch.
starch synthesis occurs within chloroplasts. The rst step is a condensation of glucose-1-phosphate with ATP. Starch synthase then transfers glucose residues from this molecule to the non-reducing end of a pre-existing molecule of starch
Q 18)
The Xylem.
Xylem transports water and nutrients from roots to all the plant shoot parts as it consists of specialised water conducting cells.
