Hint: The ripened ovary forms the fruit while the ripened ovule is formed by seed. Edible part of the plant is fruit, tegmen and testa are the covering of seeds, which are formed from inner and outer integument. The other covering of seed is also found which is known as ariel. Which act as edible portions of some fruits.

Complete answer:
An aril is also known as arillus,. it is accessory seed covering which is outgrowth from a seed that covers the seed aril grows form the point of attachment of seed to ovary known as hilum of funiculus, aril creates fruit which is basically false fruit. Aril is the edible part in the litchi which appears as a fleshy gelly part that covers the seed.
