Question

For bottle cork, the latter is cut in such a way that lenticels appear.
(A)Vertically
(B)Obliquely
(C)Transversely
(D)Blocked

Answer 1

Hint: Lenticels are formed in such a way in cork cells that they act as perpendicular to the surface of the cork cells. They are present from top to bottom in the cork cells.

Complete answer:
Lenticels are formed vertically in the cork cells. So, the bottle of cork is to be cut in a vertical direction so that lenticels will appear. Lenticels are found on the epidermis of different plant organs like fruits or the periderm of bark.

Lenticels are opening on various parts of the plant like fruit, stems, and tubers and are filled with loosely connected cells that help in the passing of air through it.
They appeared as raised, oval, elongated areas on stems and roots Lenticels are also present in fruits and can be noticed easily in pears. Even potato tubers also contain lenticels. In woody plants, it appears as a rough,cork-like structure. Lenticel breakdown is an apple skin disorder in which lenticels develop dark-colored 2 to 8 mm diameter pits.
The shape of lenticels is one of the characteristic features used for tree identification. Lenticel transpires only a small amount of water vapor. Their pores are always open.
So, the correct answer is ‘Vertically’.

Note: Lenticel is different from stomata in many ways. Stomata appear in the epidermis of the leaf. Lenticels appear in the periderm of woody trunk or stem. In stomata Guard cells are present but in Lenticels no guard cells are present. The main difference is stomata is formed during primary growth but lenticels are formed during secondary growth.
