Question

Albuminous seeds store their reserve food mainly in?

Answer 1

Hint: Dicotyledonous and Monocotyledonous seeds are classified as endospermic or endospermic based on the presence or lack of endosperm.
Because the endosperm is not entirely destroyed during embryonic development because the endosperm retains nourishment, albuminous seeds or endospermic seeds retain some endosperm.
Cotyledons are frequently smaller and less developed in endospermic seeds. Zea mays (Maize), Triticum Vulgare (Wheat), Barley, Oryza sativa (Rice), Cotton, Ricinus communis (Castor), and onion are other examples.
'Wheat, Barley, Castor' has albuminous seeds.

Complete answer:
Non-endospermic or exalbuminous seeds are seeds that store food resources in their cotyledons.
Endospermic or albuminous seeds are seeds that retain food ingredients in their endosperm.
Cotyledons store food material in exalbuminous seeds.
The section of the axis between the radicle and the cotyledonary node is known as the hypocotyl.
Perisperm is a nucellus that doesn't go away.
Endosperm- In albuminous seeds, it stores food stuff.

Additional information:
The seeds of the majority of angiosperms have endosperms. It offers food for the developing embryo. In dicotyledons, the endosperm is replaced by fleshy cotyledons. In monocotyledons, the endosperm survives and stores nourishment in mature seeds.
Functions-
Endosperm is necessary for the development of an embryo and stores the food reserve. It also provides nutrients and protects the growing embryo.
Gene expression and seed germination have been found to be regulated by endospermic tissues.
Endosperm regulates embryonic growth by inducing signals in response to environmental stimuli.

Note:

Albuminous	Non- Albuminous
The endosperm is a yellowish, fleshy, somewhat flattened and oval mass within the membrane that carries a lot of oil.	The food is kept outside the embryo, in the endosperm, rather than in the two cotyledons of the embryo in this type of seed.
The embryo is acquired by breaking open the endosperm and remaining embedded inside. Two cotyledons are slender and whitish.	The kernel is discovered when the seed coat is opened. The embryo is the kernel of dicotyledonous non-albuminous seeds.
Eg. maize, barley, castor and sunflower	Eg. pea and groundnut
