Solution

The correct option is D A and C
Endosperm is formed as a result of a triple fusion between a male gamete and two polar nuclei.
Syngamy is the fusion of male and female gametes and results in the formation of zygote.

In a dicotyledonous embryo the root tip is covered with a root cap.

In monocotyledonous embryo radicle and root cap are enclosed in an undifferentiated sheath called coleorrhiza. Coleoptile encloses the shoot tip in monocots.

Grass is a monocotyledon having a single cotyledon called scutellum.

Hence the statements A and C are incorrect and statements B and D are correct.
