Question

What is the developmental fate of the chalazal chamber in helobial type endosperm?

विकल्प

• It undergoes fewer nuclear divisions and typically degenerates.

• It differentiates directly into the embryo suspensor.

• It forms the white kernel through centripetal cellularization.

• It undergoes extensive free nuclear divisions and forms the primary nutritive tissue.

Answer 1

In helobial endosperm, the larger micropylar chamber undergoes extensive free nuclear divisions followed by wall formation, while the smaller chalazal chamber undergoes fewer nuclear divisions and typically degenerates.
