Two friends, Rati and Mohan, are discussing about double fertilization that takes place in
plants. They came across the diagram as shown in the image. Read the conversation
between Rati and Mohan and mark the correct option:
Rati: (a) is the pollen grain, from which (b) pollen tube is arising and entering (c) ovule. Pollen
grain moves inside the pistil through the pollen tube and fertilize the egg.
Mohan: (a) is a pollen grain, from which (b) pollen tube is arising and entering (c) ovule. Male
gametes moves inside the pistil through the pollen tube and fertilize the egg.

Answer:
events that are responsible for it.
Answer
Double fertilization occurs in plants of both castor and groundnut but the mature seeds of groundnut are non-albuminous and castor are albuminous. The post fertilization events that are responsible for it are:
Double fertilization occurs in plants of both castor and groundnut but the mature seeds of groundnut are non-albuminous and castor are albuminous. The post fertilization events that are responsible for it are:The primary endosperm nucleus divides repeatedly to give rise to a free nuclei and the stage of endosperm development is called free nuclear endosperm. The cell wall forms after giving rise to a cellular endosperm.

The cell wall forms after giving rise to a cellular endosperm.If the endosperm is fully consumed by the growing embryo then non-albuminous seeds are formed as in groundnut. If the endosperm is retained then it forms albuminous seeds as is the case with castor plant
