Detailed explanation-1: -Astrosclereids are another type of sclereids and have been found in the floating leaves of water lily. They are branched, pointed, and often star-shaped (hence the name astrosclereid).

Detailed explanation-2: -The Astrosclereids provide strength to the leaves and thus they act as strengthening agents. Nymphaea is commonly known as water lilies. They have an angular and erect stem with eaves growing from the rhizome. They have long petioles.

Detailed explanation-3: -Star-shaped or branched astrosclereids make water lily leaves (Nymphaea sp.) tough but pliable, allowing them to withstand the tearing forces of waves and currents. The conducting types of sclerenchyma are the tracheids and vessel elements of the xylem, the tracheary elements of plants.

Detailed explanation-4: -Macrosclereids-They are elongated sclereids usually found in the outer layer in the seed coat of legume seeds. Osterosclereids-(also called bone or hour-glass cells) are columnar cells similar to macrosclereids except they are enlarged at the ends making them bone-shaped. More items
