Question

The small projections present on the surface of the pineapple fruit represent
A.Persistent styles
B.Persistent stamens
C.Persistent calyx
D.Persistent bracts

Answer 1

Fruits are the structure that contains seeds in angiosperms which are produced from the ovary after flowering. The flowering plants can be divided into three basic types- annuals, biennials, and perennials. Types of fruit are fleshy fruits, dry fruits, aggregate fruits, and multiple fruits. Fleshy fruits include pome, drupe, berry, and hip while dry fruits include legumes, capsules, nuts, grains, follicle, samara, schizocarp etc.

Complete answer:
Option A- Persistent styles: Style is the long, slender neck-like part of the female reproductive part of a flower i.e. the carpel. It provides a way to the ovary for the pollen.
Option B- Persistent stamens: Stamen is the male reproductive part of a flower which consists of an anther and a filament and produces pollen.
Option C- Persistent calyx: The calyx is also known as sepals which are leaf-like structures green in colour and covers the bud form of the flower.
Option D- Persistent bracts: Bracts are also leaf-like structures that are present just below a flower in a plant. It is also called a modification of leaf. They differ in the shape from leaves present on a plant.

Thus, the correct option is option D- Persistent bracts.

Note:
Pineapple is multiple fruits which consist of the gynoecium i.e. group of carpels, of several flowers that constitute the inflorescence.
The flowering plants can grow annually that means they grow in a single season or year and flower once while biennials flower once but grow for two seasons. Perennials can flower multiple times and for many years.
