Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
The examples of cellular endosperm are (1) Citrus, Malea, Primula (2) Adoxa, Cetranthus, Datura (3) Phoenix, Acer, Arachis (4) Impatiens, Magnolia, CetranthusA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: C
Solution :
Cellular endosperm is found in 25°/o angiospermic families in which the embryo develops slowly. During cellular type of endosperm development, the primary endosperm mother cell divides by mitotic divisions and each division is followed by a cell wall formation, eg, Adoxa, Cetranthus, Datura, Impatiens, Magnolia, etc. Nuclear endosperm is more common type of endosperm occurring in about 56% of those angiospermic families in which embryo grows faster. eg, Acer, Arachis, Phoenix, Citrus, Primula, Calotropis, etc.
