Open in App
Solution
The correct option is B Macrosclereids
- Macrosclereids are elongated sclereids. Sclereids are the reduced form of sclerenchyma. It is usually found in the outer layer of seed coat of legumes. These cells are responsible for restricting water uptake by hard seeded legumes.
- Brachysclereids resembles parenchyma cells in shape but are made almost entirely of secondary cell wall. These cells are called as stone cells, because they form the girth in pear fruit.
- Astrosclereids are found in specialized tissues like floating leaves of water lily. Astrosclereids are branched, pointed, irregular (often star - shaped)
sclereids. - Trichosclereids are found in leaves of olive and areal roots of swiss cheese plant.
