• It can be found in various seeds, such as beet and black pepper seeds, coffee, and so on.
• The nucellus of an ovule is a mass of parenchymatous cells encased within the integuments.
• It is the location of a large food reserve.
• Perisperm is the nucellus that remains in the seed after it has matured.
• Diploid cells make up the chromosomes.
• The endosperm is surrounded by perisperm.
• In nature, it is usually dry.
• Perisperm is a nutritive tissue layer found in the seed of several flowering plants.
