Types and Significance of Fruits - Class VII

The most important foods for human survival includes vegetables, cereals, fruits, pulses and oil seeds. Most of these are fruits. For example, caryopsis is popularly called as grain and is the fruit typical of the family Poaceae (or Gramineae), which includes wheat, rice, and corn. Considering that the fruit wall and the seed are intimately fused into a single unit, and the caryopsis or grain is a dry fruit, little concern is given to technically separating the terms "fruit" and "seed" in these plant structures. So, most important foods are derived from fruits and not from stem, leaves and roots. Thus, option B is correct.

Water melon is a Pepo fruit. Berries are another type of fleshy fruit, they are simple fruit created from a single ovary. The ovary may be compound, with several carpels. Pepo are berries where the skin is hardened.
Thus, the correct answer is option C.

When the septa between the locules of the capsule split and the fruit opens to release the seeds, then this type of dehiscence is called as septicidal dehiscence. For example, Datura. The fruit of Datura is septicidal capsule but its dehiscence is of septifragal nature in which placenta remains attached in the centre of undivided fruit and pericarp's segment becomes separated.

Fruit of groundnut is a lomentum. Lomentum is a simple, dry, schizocarpic fruit. The fruit is constricted or partitioned between seeds into a number of one-seeded compartments. The fruit breaks into one seeded indehiscent segments. 

Pepo (berries) is a type of fleshy fruit. They are simple fruit created from a single ovary. In pepo, the berry skin is leathery as in Cucurbitaceae family.
So, the correct answer is 'Cucurbitaceae'

Caryopsis is a type of simple dry fruit that has one seed or monocarpellate (formed from a single carpel) and indehiscent (not opening at maturity). In a caryopsis, the pericarp is fused with the thin seed coat and the fruit wall and the seed are intimately fused into a single unit example Maize
So, the correct answer is 'one seeded fruit'
