The angiospermic endosperm, except in special cases, is a triploid (3n) tissue as it is a product of triple fusion involving double fertilisation. It is thus, distinct from the endosperm of gymnosperms and heterosporous pteridophytes, where the endosperm is a

diploid before fertilisation

simple haploid (n) tissue of the gametophyte no involving any complication like polar fusion or fertilisation

polyploid formed after simple fertilisation

haploid formed after fertilisation

There are at lest two families where the product of double fertilisation soon disintegrates and endosperm development is completely absent in. These includes

$ Double fertilization and triple fusion occurs in Angiosperms. ! Triple fusion produces triploid type of endosperm.

Assertion : In angiosperms, endosperm development precedes embryo development. Reason : Double fertilisation ensures that the nutritive tissue is formed before the zygotes starts cleaving so that the energy spent on the formation of endosperm does not get wasted.

Assertion. The endosperms is generally triploid (3n). Reason. It develops from primary endosperm nucleus formed by fusion of haploid male gamete and diploid secondary nucleus.

Select the correct statements from the following I. Endosperm is generally triploid in angiosperms, II. All angiosperms have monosporic and endosporic embryo sac, III. Angiosperms are characterised by double fertilization, IV. All angisoperms show indirect pollination and siphonogamy
