Question

Monocot seeds are mostly endospermic, which of the following is a monocot non -endospermic seed?

• A. Oryza
• B. Castor
• C. Alisma
• D. Avena

Answer 1

The correct option is C Alisma

Monocot seeds are mostly endospermic, but Alisma is a monocot non -endospermic seed. In most monocotyledons the seeds are endospermic. The embryo is embedded in the endosperm which the seedling will use upon germination. In few they are non-endospermic seeds like that of dicotylednous plants where the endosperm is absorbed by the embryo as the latter grows within the developing seed and the cotyledons of the embryo become filled with stored food.
Therefore, the correct answer is option C.
