In the most common type of endosperm development:
- The PEN undergoes successive nuclear divisions to give rise to free nuclei.
- Subsequently, cell wall formation occurs.
This process implies that the initial divisions of the PEN do not involve cell wall formation; instead, the formation of free nuclei precedes cell wall development. This sequence is a fundamental aspect of endosperm development, ensuring the creation of a structured cellular framework during this critical stage of plant growth.

Endosperm Development in Plants
Endosperm development in plants is a crucial process that involves the formation of storage tissues within the seed. The most common type of endosperm development follows a specific pattern.
Process of Endosperm Development
- The primary endosperm nucleus (PEN) undergoes successive nuclear divisions to give rise to free nuclei.
- Subsequently, cell wall formation occurs around these free nuclei to form the endosperm tissue.
Explanation of Option B
Option B states that the PEN undergoes successive nuclear divisions to give rise to free nuclei before cell wall formation occurs. This process is known as free nuclear division and is the most common type of endosperm development in plants.
During free nuclear division, the PEN undergoes multiple rounds of nuclear divisions without cytokinesis, resulting in the formation of a multinucleate syncytium. These free nuclei then become surrounded by cell walls to form the endosperm tissue.
This process allows for efficient storage of nutrients within the endosperm, which is essential for the developing embryo. The formation of cell walls around the free nuclei ensures the structural integrity of the endosperm tissue and facilitates nutrient storage and transport.
In conclusion, option B accurately describes the most common type of endosperm development in plants, where the PEN undergoes successive nuclear divisions to give rise to free nuclei before cell wall formation occurs.
