Answer 2

Because they form within the seeds, cotyledons are known also as seed leaves. Flowering plants, called angiosperms, have embryos within their seeds that form one or two cotyledons, also often referred to as "seed leaves". Those with one cotyledon are known as monocotyledons or monocots.❤️
