Perisperm is the persistent, dry, diploid (2n)
) nutritive tissue in certain seeds that develops from the maternal nucellus after fertilization. It surrounds the endosperm to nourish the developing embryo. Common examples include black pepper, beet, and coffee.
Key Characteristics and Facts:
Origin: Develops from the nucellus (part of the ovule) that remains after fertilization.
Composition: It is a nutrient-rich parenchyma tissue.
Distinction: While endosperm is typically absorbed by the developing embryo, perisperm is the remnant of the nucellus that persists in the mature seed.
Examples: Found in Families like Amaranthaceae (Beet, and Piperaceae (Black pepper,

Difference Between Perisperm and Endosperm
Perisperm: Diploid (2n)
), maternal origin, remnants of nucellus.
Endosperm: Triploid (3n) product of double fertilization.
