Question

Define
(i) Sorosis
(ii) Pome

Answer 1

Hint: Fruits are the by-product of reproduction in plants. In addition to it, both soosis and pome are types of fruit. They are named on the basis of their shape and structure.

Complete step by step answer: The fruit develops from a ripe ovary or any floral part after the pollination and fertilization.
-Depending on which floral part the fruit develops it is classified as true fruits, false fruits, or parthenocarpic fruits. Depending on their structure fruits are also classified as simple, aggregate, and composite.
-Any multiple fruit which is derived from the multiple ovaries in an infructescence which is usually fleshly is called sorosis. Sorosis is a type of composite fruit which is developed from catkin, spike, and spadix inflorescence. Such fruits include remnants of floral tissue called as perianth. Perianth are the sterile parts of the flower which collectively includes the sepals, petals and tepals. The fruity stage of an inflorescence is called infructescence. Examples of sorosis fruits are pineapple, mulberry, and jackfruit. The edible part is called the perianth and peduncle.
-A type of fruit produced by flowering plants in the subtribe Malina of the family Rosaceae is called pome. Pome fruit composes one or more carpels that are surrounded by accessory tissues. Within the core, the carpels of pome are fused. Pome fruit is surrounded by fleshy edible thalamus with the core in the center. Apple is an example of pome fruit.

Note: The pome type fruit which has stony endocarp instead of leathery endocarp is called a polypyrenous drupe. Plants that produce pome type fruits are whitebeam, rowan, pear, and quince.
