(ii) Phloem parenchyma is made of elongated non-tapering cylindrical cells that have a scanty cytoplasm.
(iii) Phloem fibers are made of parenchymatous cells.
(iv) Companion cells help in maintaining the pressure gradient in the sieve tube.
(v) The phloem parenchyma stores food material and other substances like resins, latex, and mucilage.

How many of the given statements are correct?

• A. Three
• B. Two
• C. One
• D. Four

Answer 1

The correct option is A Three

i) The sieve tube elements and companion cells are connected by pit fields present between their common longitudinal walls – correct.
ii) Phloem parenchyma is made of elongated non-tapering cylindrical cells which have scanty cytoplasm – false.
(iii) Phloem fibres are made of parenchymatous cells - false. They are made up of sclerenchymatous cells.
(iv) Companion cells help in maintaining the pressure gradient in the sieve tube - correct
(v) The phloem parenchyma stores food material and other substances like resins, latex and mucilage – correct.
so correct answer is ‘Three’.
