The gritty pulp of fruits like guava and pear is due to it’s presence
|
Detailed explanation-1: -Sclereids are found in fruit walls of nuts, the pulp of fruits like guava, pear, and sapota, and seed coats of legumes.
Detailed explanation-2: -Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants. The presence of numerous sclereids form the cores of apples and produce the gritty texture of guavas.
Detailed explanation-3: -So, the correct answer is ‘Sclereids.
Detailed explanation-4: -The grittiness of pear fruit is caused by stone cells which are also known as sclereids. Sclereids are sclerenchyma cells with thick, lignified walls that function in providing structural support and strength to tissues. It removes the stress in the fruit which is caused due to over-ripening.
