BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Drupes (stone fruit): Drupes are very common and include mangos, cherries, pears, olives, plums, and coffee “berries”. Plants that produce drupes often co-evolved with different animals for seed dispersal.

Detailed explanation-2: -Option B: Trapa is a nut, not a drupe. This is the correct answer. Drupe is an indehiscent fruit which is also known as stone fruit.

Detailed explanation-3: -The membrane is encased in an edible layer of flesh. Trees are deciduous and have a dormant winter period that requires cold temperatures for the tree to properly break dormancy in spring. Apples, pears, nashi and quince are pome fruits, grown from spring blossom and harvested from late summer through to late autumn.

Detailed explanation-4: -Drupes have a fleshy mesocarp but a tough, leathery endocarp. An avocado is fleshy throughout, so it cannot be considered a drupe.
