What does perisperm mean?
A perisperm is a remnant of the nucellus, the tissue surrounding the ovule in a plant, that remains attached to the seed after fertilization. It is a type of endosperm that is formed before fertilization.
Example
"The perisperm of the coconut palm is a hard, stony structure that surrounds the embryo."
