Question:
Repeated nuclear division without formation of cell wall and appearance of large central vacuole pushing the newly formed nuclei towards the periphery is observed in ________ endosperm.
Repeated nuclear division without formation of cell wall and appearance of large central vacuole pushing the newly formed nuclei towards the periphery is observed in ________ endosperm.
Show Hint
No wall is formed during the first divisions of this endosperm type.

- nuclear
- mosaic
- helobial
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
After double fertilisation the primary endosperm nucleus divides to form the endosperm. The pattern differs among plants.
Step 2: Identify the type
In nuclear endosperm the division is repeated without wall formation, giving many free nuclei. A large central vacuole then pushes the nuclei to the periphery, as in coconut water.
Step 3: Why the other options fail
In cellular endosperm every division is followed by wall formation, and in helobial endosperm the first division forms a wall.
Final Answer:
The description fits nuclear endosperm. \[ \boxed{\text{(B) }\text{nuclear}} \]
