Which of the following is not true for plant cells?

• A. Bulliform cells are present only in isobilateral leaves
• B. Subsidiary cells are part of the stomatal apparatus
• C. Lenticels are pores in woody plants for gas exchange
• D. Companion cells are part of the epidermal tissue system

Answer 1

The correct option is D Companion cells are part of the epidermal tissue system

Bulliform cells are found in the upper epidermis of monocot leaves and help in the folding of the leaves.

Subsidary cells are parenchymatous cells found around the guard cells of a stomatal apparatus.

Lenticels are openings found in the woody plants in place of the stomata and are formed during the secondary growth of the plant.

Companion cells are one of the cell components of the phloem tissue, the others being sieve tubes, phloem fibers and phloem parenchyma.
