Perisperm is found in -(a)Black Pepper(b)Wheat(c)Maize(d)Groundnut

The correct answer is (a) Black Pepper.
Perisperm is a part of the seed that is a source of stored food, found in some seeds. It is the tissue surrounding the embryo and is derived from the nucellus (the central part of the ovule). In plants that have perisperm, this tissue stores food for the developing embryo during germination.
Black pepper (Piper nigrum) is one of the plants where the seed contains perisperm. The perisperm in black pepper surrounds the embryo and acts as a storage tissue, providing nourishment during seedling development.
Here’s an explanation of the other options:
• (b) Wheat: Wheat seeds store food in the endosperm, not perisperm. The endosperm is the tissue that provides energy to the developing embryo.
• (c) Maize: Like wheat, maize (corn) also stores its food in the endosperm rather than in perisperm.
• (d) Groundnut: Groundnut (peanut) seeds store food in the cotyledons, which are part of the embryo, not in perisperm.
Therefore, black pepper is the correct answer, as it contains perisperm in its seeds.
