Answer #1

Answer: (a) these are groups of living cells

Explanation:

Sclereids are cells with thick, lignified walls. They are grouped with fibres under the general term sclerenchyma. They differ from fibres in generally being shorter in relation to their length, but there is some overlap in the range of cells.

Characteristic examples are brachysclereids or the stone cells (called stone cells because of their hardness) of pears (Pyrus communis) and quinces (Cydonia oblonga) and those of the shoot of the wax plant (Hoya carnosa).
