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.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
c

In some seeds, the endosperm persists in the seed as food storage tissue. Such seeds are called endospermic or albuminous e.g., Castor, Maize, Wheat, Barley, rubber, coconut. In others the endosperm is completely of embryo is then stored in cotyledons which become massive. Such seeds are non-endospermic or ex-albuminous,e.g., gram, bean, groundnut.

Assertion (A): One of the examples of an albuminous seed is Maize. Reason (B): Endosperm gets completely consumed in the maize seed.

Some seeds retain a part of endosperm as it is not completely used up during embryo development, while in some seeds, remnants of the nucellus are also persistent. Choose the option with example of the respective types of seeds.

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.
