Seeds are regarded as products of sexual reproduction because they
1 can be stored for a long time.
2 are result of fusion of pollen tube.
3 are result of fusion of gametes.
4 give rise to new plants.
Explanation:
(c) Morphologically, seed (ripened ovule) is the integumented mature, megasporangium which is developed from a fertilized ovule and is with an embryo (future plant, enclosed by seed coat.)

It is a proteinous layer and the outer covering of endosperm which separates the embryo. Identify the layer.
1 Tegmen
2 Scutellum
3 Hyaline layer
4 Aleurone layer
Explanation:
(d) The aleurone layer is the outermost layer of the endosperm, followed by the inner starchy endosperm. This layer of cells is sometimes referred to as the peripheral endosperm. It lies between the pericarp and the hyaline layer of the endosperm.

2 tegmen
3 hilum
4 micropyle
Explanation:
