Non-endospermic dicots

Definition

Non-endospermic dicots are flowering plants whose seeds lack an endosperm at maturity. Instead, the cotyledons serve as the main storage tissue for nutrients.

5 Must Know Facts For Your Next Test

1. Non-endospermic dicots store nutrients in their cotyledons rather than in an endosperm.
2. Examples of non-endospermic dicots include beans, peas, and peanuts.
3. During seed germination, the cotyledons provide essential nutrients to the developing plant embryo.
4. Non-endospermic seeds undergo double fertilization but do not retain the triploid endosperm tissue.
5. These seeds are also referred to as exalbuminous because they lack a persistent endosperm.
