Hint: In a plant, the seed-bearing structure which is formed from the ovary is called a fruit. The part of the flower from which the fruit develops determines the type and external appearance of the fruit.
Complete answer:
Fruits develop from the ripe ovary or floral part, after pollination. Based on the number of ovaries and flowers involved in the development of fruit, fruits are categorized into three different types i.e. simple, aggregate and composite. Fruits that develop from a single ovary and single carpel are called simple fruits and they can be fleshy or dry. Watermelon, tomato, and orange are examples of simple fruits. Fruits that develop from multiple ovaries of the same flower are called aggregate fruits. Blackberries are aggregate fruits. When a number of parts of flowers come together to form a big fruit, it is called a composite fruit. Pineapple is a composite type of fruit. It is also called a sorosis type. It is fleshy and develops from spike, spear, or catkin. The flower associated with the fruit by succulent petals and the axis bearing the flower grows becoming fleshier or woody. The entire inflorescence is converted into a compact fruit. Edible parts of a sorosis type of fruit are perianth and peduncle.
So, the correct answer is ‘Sorosis’.
Note:
Some types of fruits are formed from one or more carpels with surrounding accessory tissue. It has certain interruptions in the accessory tissue which are called receptacles. Most fruits of the citrus family are of hesperidium type. These are berrylike but with a tough and leathery rind. Carcerulus fruits have multiple seeded fragments that adhere to the central axis. Mallow is an example of carcerulus fruit.
