Question

What is the direction of movement of sugar in phloem
A. Non-multidirectional
B. Upward
C. Downward
D. Bi-directional

Answer 1

The phloem is a vascular tissue which is responsible for transporting sugar to sink tissues, for example, non-photosynthetic root cells of flowers developing from source tissue, for example, photosynthetic leaf cells phloem also transport other molecules such as proteins and mRNA throughout the plant.

Complete step by step answer: The sugar that during photosynthesis is formed by the plant is an essential component of plant nutrition. Like water, the vascular system carries sugar usually in the form of sucrose while glucose is the original photosynthetic product in all parts of the plant. Phloem is the vascular tissue which is responsible for transporting Organic nutrients around the body of the plant which carries nutrient requiring dissolved Sugars from the leaves for the storage sites to other parts of
the plant. Within the phloem, sugar migrates to a region of low osmotic concentration and low water pressure, called sinks, from the areas of high osmotic concentration and high water pressure, which is known as the source.
