Question

‘Patua’ of Hibiscus sabdariffa is
(a) Secondary phloem
(b) Collenchymatous hypodermis
(c) Pericycle
(d) Epidermis

Answer 1

Hint: Patua is obtained from the bast fiber of Hibiscus sabdariffa , which is used for making jute. Bast fiber is formed by dead tissue of a plant which is composed of cellulose and lignin and has less water and carbon dioxide holding capacity.

Complete answer:
Hibiscus sabdariffa belongs to the family Malvaceae, Hibiscus sabdariffa is also known as a roselle plant which is mainly found in south-east Asia. This plant is primarily used for its bast fiber because the bast fiber of this plant is durable. Patua is the secondary phloem of plant roselle. Secondary phloem consists of numbers of fibers in the form of patches and bands.

Additional Information: In-plant secondary phloem form from vascular cambium. Secondary growth is responsible to increase the girth of plants, it is present with cambium and together with cambium, it forms a secondary part of the plant. The bark which is present outside the plant body is a dead tissue that helps in gas exchange through lenticels.
Collenchymatous hypodermis is a living tissue with the presence of the nucleus, it has a thick cell wall with the vacuole. collenchymatous hypodermis is present below the epidermis region of the plant. It has a deposition of lignin, it makes the path for water conduction from the outer surface of the plant toward the inner xylem.
In the dicot plant epidermis shows a small outgrowth known as trichome, this trichome is present with the layer of cuticle. Vascular bundles are arranged in a ring of cambium which divides to expand the girth.
Hibiscus sabdariffa is not only important for jute production, it is also used for medicinal purposes as a diuretic and mild laxative. Its fruit is also used for making vegetables and beverages. The color that obtains from calyces is used as a food coloring agent.
So, the correct answer is Secondary phloem.

Note: Patua is also a Bengali word used to dedicate a painter. They make traditional paintings and modeling of god. Both these patua spells are the same but they are different, Hibiscus patua is relatable with plant bast fiber.
