Question

Which of the following statement about the flow of sap through phloem is true?

• A. Sap moves through phloem under pressure
• B. Sugars move into phloem sap by active transport
• C. Phloem sap moves through the inside of living cells
• D. All of the above

Answer 1

The correct option is D All of the above

The flow of sap through the phloem:

Sap moves through phloem under pressure.

Sugars move into phloem sap by active transport by the expenditure of energy.

Phloem sap moves through the inside of living cells.

Phloem sap consists primarily of water, with sugars, hormones, and mineral elements dissolved in it. It flows from the site of production of carbohydrates to the site of their metabolization.

So, the correct answer is option D.
