What will happen to the seeds if there is no cotyledon?

Cotyledon removal resulted in reduced growth and leaf number per plant in young seedlings.

How important is cotyledon in seeds?

Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.
