A - B - C - D - Which of the following is correct for above diagrams :
1 A and B represent ex-albuminous seeds
2 C and D represent albuminous seeds
3 A and B represent albuminous seeds
4 C and D represent perispermic seeds
Explanation:
C In albuminous seeds the cotyledons is thin and membranous and the endosperm persists and nourishes the seed during the early development of the seed. Cotyledons function only as food sucking organs, not as food storage organs Example as castor seed, coconut and maize. In the given diagrams \(\mathrm{A}\) and \(\mathrm{B}\) represent albuminous seeds. - Seeds which lack endosperm at maturity are called non-endopermic or ex-albuminous seeds. Example as pea, bean and groundnut.

Which of the following is not found in maize seed:
1 Coleorhiza
2 Coleoptile
3 Scutellum
4 Perisperm
Explanation:
D Perisperm is a layer of nutritive tissue that surrounds the embryo of a seed. There are three parts in an ovule The integument that form the outer layer, nucellus and the female gametophyte in its center. Nucellus in the inner structure of the ovule which may develop into the perisperm that feeds the embryo. In maize seeds the perisperm is absent. As maize is a monocot coleorhiza, coleoptile and scutellum are found in maize. Hence perisperm is not found in maize seed.

'Scutellum' is the of monocotyledonous plant.
1 embryo axis
2 cotyledon
3 endosperm
4 coleoptyle
Explanation:
B Typical dicotyledonous embryo contains two cotyledons. The portion above the level of cotyledons is called epicotyl (embryonic shoot) or plumule and portion below the level of cotyledons is known as hypocotyls (embryonic root) or radicle embryo of monocotyledons have only one cotyledon called scutellum.

The scutellum observed in a grain of wheat or maize is comparable to which part of the seed in other dicotyledons
1 Aleurone layer
2 Plumule
3 Radicle
4 Cotyledon
Explanation:
D Embryo of monocotyledons have only one cotyledons called scutellum. - The embryonic axis runs the length of the embryo. On end of the embryonic axis is the plumule, the young shoot apex, which includes the shoot apex. Which includes the shoot apical meristem and developing leaf primordia. At the other end of the embryonic axis is the radicle. - The embryonic axis does not include the catyledons. The portion of the embryo between the cotyledon attachment point and the radicle is known as the hypocotyl. The portion of the embryonic axis between the cotyledon attachment and the shoot tip is the epicotyl.
