Answer:
Correct Answer: C
Solution:
The cellular endosperm is characterized by the presence of a free nuclear stage.
The division of the primary endosperm nucleus and a few subsequent nuclear division are followed regularly by wall formation.
The occurrence of haustoria is a common feature of this type of endosperm; the haustoria may be micropylar or chalazal.
Occasionally, both types of haustoria are present in the same plant.
