Explanation:
Detailed explanation-1: -Hence, tracheids are not an element of phloem tissue, so the correct option is (1) Tracheids.
Detailed explanation-2: -Pollen is not transferred within the plant.
Detailed explanation-3: -So the correct answer is ‘As hydrostatic pressure in phloem sieve tubes increases, pressure flow stops and sap accumulates in phloem’.
Detailed explanation-4: -Final answer: Tracheids are not the element of phloem tissue.
