Read the following statements and find out the incorrect statement. a. Embryo development precedes endosperm development. b. Though the seeds differs greatly the early stages of embryo development (embrogeny) are similar in both monocotyledons and dicotyledons. c. A typical dicotyledonous embryo consists of an embryonal axis and two cotyledons. d. Endosperm may either be completely consumed by the developing embryo (e.g., castor and coconut) before seed maturation or it may persist in the mature seed (e.g., wheat, rice , pea, groundnut and beans). e. The coconut water from tender coconut is cellular endosperms and the surrounding while kernal is the nuclear endosperm.

Identify the incorrect statements regarding the post-fertilization development. I. Endosperm precedes embryo development. II. Ovule develops into seed. III. Ovary develops into fruit. IV. Male gamete fuses with egg cell. V. Primary endosperm nucleus is formed.

Assertion : Ex-albuminous seeds do not possess any residual endosperm, as it is completely consumed during embryo development., Reason : Wheat, castor, pea and groundnut are all the examples of ex-albuminous seeds.

Seeds contain embryo.
