What force does the pressure-flow model depend on to move sugars?

Biology
1 answer:
olga nikolaevna [1]3 years ago
4 0

Answer:

Water follows the sugar molecules into the sieve elements through osmosis (since water passively diffuses into regions of higher solute concentration). This water creates turgor pressure in the sieve elements, which forces the sugars and fluids down the phloem tubes toward the sinks.

Hopefully this helps!

Which type of vaccine could possibly cause a person to develop the disease? which type of vaccine could possibly cause a person
Ghella [55]
<span>The correct answer is attenuated live vaccine.</span>
<span>
Attenuated live vaccines are vaccines that use a weakened or attenuated form of the viruses or bacteria that causes a disease. Viruses or bacteria are given in a relatively small dose to replicate in the vaccinated person and to stimulate an immune response. They create a strong and long-lasting immune response but the limiting factor is that there is a possibility for a virus to revert to a form which is capable of causing disease.</span>
