Question

Branched hair-like sclereids are called ______________.

• A. Trichosclereids
• B. Fibriform sclereids
• C. Brachysclereids
• D. Polymorphic sclereids

Answer 1

The correct option is A Trichosclereids

A. Trichosclereids

EXPLANATION: Several types of sclereids are found namely

• brachysclereids
• macrosclereids
• trichosclereids
• osteosclereids
• astrosclereids

The types vary from each other mainly in their morphology and one can deduce that from their names i.e. "tricho" refers to hair hence trichosclereids will be hair-like while "osteo" refers to bone, so they are bone shapedalso known as bone or hour-glass sclereids. "Astro" refers to stars and astrosclereids resemble star-like appearance. Brachyosclereids resemble parenchyma cells in shape while macrosclereids are bigger, elongated ones found in outer layers of seed coats of legume seeds.

So, the correct answer is A.
