• B. A - 1, 2, 5, B - 4, 6, 7, C - 3, 8, 9
• C. A - 1, 4, 5, B - 2, 8, 7, C - 3, 6, 9
• D. A- 1, 4, 5, B - 2, 6, 9, C - 3, 8, 7

Answer 1

The correct option is A A - 1, 4, 5, B - 3, 7, 8, 9, C - 2, 6

Brachysclereids are small, unbranched, isodiametric shaped cells. Given explanation matches with Diagram A. They are also called as stone cells. These cells are present in cortex, phloem and in pulp of fruits as guava, pear etc. It gives gritty texture in pulp of guava, pear. Hence, A- 1, 4, 5
Osteosclereids are barrel shaped or cone shaped or columnar shaped cells with dilated ends. Given explanation matches with diagram B. It forms palisade covering of seeds of Fabaceae family forming legumes like Pisum. It is also present in leaves of certain xerophytes. Hence, B- 3, 7, 8, 9.
Trichosclereids are elongated hair like cells. Given explanation matches with Diagram C. It is also called as rod cells. These are present in intercellular spaces in the leaves and stem of certain hydrophytes. Hence, C- 2, 6.
Thus, the correct answer is option A.
