Petiole of lotus and tea leaves have:
Macrosclereids
Brachysclereids
Trichosciereids
Astrosclereids
Answers (1)
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.
Astrosclereids - They are branched, pointed, irregular (often star-shaped) sclereids. Astrosclereids are not a common type of sclereid. They can be found in specialized tissues like the floating leaves of water lilies, lotus and tea leaves.
Trichosclereids - These are uncommon cells. They can be found in the leaves of olive and the aerial roots of the Swiss cheese plant (Monstera sp.). These long trichosclereids are from macerated roots of the Swiss cheese plant.
Hence, the correct answer is option 4.
