HORTICULTURE

Detailed explanation-1: -Parenchyma makes up the chloroplast-laden mesophyll (internal layers) of leaves and the cortex (outer layers) and pith (innermost layers) of stems and roots; it also forms the soft tissues of fruits.

Detailed explanation-2: -Apple fruit flesh or cortex comprises of homogeneous parenchyma-type cells. There is a variation of cell sizes across the apple fruit with cells under the skin being smaller (70 uM), increasing in size (to approx 250 uM) towards the centre of the flesh [12, 13].

Detailed explanation-3: -The apple fruit has two major fleshy tissues: cortex and pith (Fig. 1a). Two hypotheses, receptacular and appendicular, have been proposed to explain the origin of these tissues [1].

Detailed explanation-4: -In angiosperms, after fertilization, the ovary forms the fruit and the ovule inside the ovary becomes the seeds. It is the parenchyma cells on the sides of the ovary becomes the pulp in the fruit.
