In dicot plants, cotyledons are present that store the food for the seed.
In monocot plant, there is only one terminal cotyledon which is known as scutellum. The second cotyledon is reduced in monocots and which is known as epiblast.
These two structures are homologous to each other as they have similar functions but different structures.
So, the correct option is 'Cotyledons and scutellum'
