LIFE SCIENCE

Detailed explanation-1: -The seeds of angiosperms, or flowering plants, contain a structure called a cotyledon, the first part of the plant to emerge from the seed. These structures provide nutrients to the embryo while it is developing and can become photosynthetic.

Detailed explanation-2: -Cotyledons are the embryonic part of the seeds of flowering plant which upon germination forms the first green leaf. If a plant contains two cotyledons in the seed then the plant is said to be a dicot plant and if a plant contains only one cotyledons in the seed then it is said to be a monocot plant.
