Explanation:
<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>
The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.
<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>
The only option that has no known effect on sugar transport in the phloem is transcription.
The correct option is a.
Answer:
Induction, in embryology, process by which the presence of one tissue influences the development of others.
Answer: The difference between structures of glucose and galactose occurs at a carbon other than the anomeric carbon.
Explanation: The cyclic structure of glucose and galactose is cannot be inter converted because the change does not occurs at the anomeric carbon.
It takes place at carbon number 3 ( Fisher's projection)which does not takes place in the opening and closing of the rings.
Anomeric carbon are the carbon that takes place in the opening and closing of the rings.
