Assertion Nuclear endosperm does not involve wall formation after each meiotic division.
Reason Coconut milk is an example of cellular endosperm.

Assertion : Nuclear endosperm is formed by subsequent nuclear division without wall formation Reason : Coconut is an example of such endosperm, where the endosperm remains nuclear throughout the development of the fruit.

Assertion : Nuclear endosperm is formed by subsequent nuclear division without wall formation Reason : Coconut is an example of such endosperm, where the endosperm remains nuclear throughout the development of the fruit.

Assertion : Cellular endosperm is formed by both nuclear division and wall formation Reason : It lacks haustoria.

Assertion (A): The coconut water from tender coconut is free nuclear endosperm and the surrounding white kernel in coconut is the cellular endosperm. Reason (R): Primary endosperm nucleus (PEN) undergoes successive nuclear divisions to produce free nuclei.

Assertion An embryo is formed after some meiotic divisions by the product formed after syngamy. Reason: An embryo is the first cell of sporophytic generation.

Express in one word only Primary endosperm nucleus division followed by wall formation.

The type of nuclear division that does not involve formation of distinct chromosomes and the formation of spindle is called ____________ .

These questions consist of two statement each, printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses. A. If both Assertion and Reason are true and Reason is a correct explanation of the Assertion. B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion. C. If Assertion is true but Reason is false. D. If both Assertion and Reason are false. Assertion: Castor seed is dicot endospermic seed. Reason. Seed is with two cotyledons and unconsumed endosperm.

This section contains Assertion (A) and Reason (R) type questions. Each question has choices (1), (2), (3) and (4), out of which only one is correct. Assertion (A) Endosperm is formed by the fusion of one male gamete and polar nuclei. Reason (R) In pea the retains a part of endosperm as it is not completely used up during embryo development.
