Which of the following is a correct statement about sugar movemetn in phloem?
Simora [160]

Answer:

a. movement can occur both upward and downward in the plant

Explanation:

The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.

yKpoI14uk [10]
In this case, the protozoa will be in category B - animal-like protist.

Animals consume other living organisms to obtain energy. Archaea and bacteria are a high level classification of different kinds of microorganisms that include many different subtypes. So these are not appropriate answers as they are not specific enough. Plant-like protists can photosynthesize which these protozoans cannot. Fungus does have similarities with animals in that it consumes living tissue to survive, however animal-like protist is the best fit for this questions.
