Sugary sap flows through phloem because of pressure changes between sugar sources and sugar sinks. There is always a concentration of sugars at a sugar source.

Sugary sap flows through phloem because of pressure changes between sugar sources and sugar sinks. There is always a higher concentration of sugars at a sugar source.

Explanation:

Options for this question:

The transport of sugar in the plant occurs in the sieve vessels of the phloem. This transport is due to the differences in hydrostatic pressure between the different compartments of the plant, as discussed in the pressure flow-hypothesis.

According to the hypothesis, sugar is more concentrated at the source and less concentrated in the areas where the sugar will be used, there being a difference or gradient of concentration.

The higher concentration of sugars in the source attracts water, which enters by osmosis, and produces an increase in hydrostatic pressure, a factor that triggers the movement of sugar by phloem.

Explanation:

i don't have a definite answer, but i would assume not based on my experiences with my friend when we both were taking a spanish course; however, it would probably still be to your benefit to look at what questions she received, just in case. a language course and a science course differ greatly, after all.
