Question

The examples of cellular endosperm are
(1) Citrus, Malea, Primula
(2) Adoxa, Cetranthus, Datura
(3) Phoenix, Acer, Arachis
(4) Impatiens, Magnolia, Cetranthus

• A. 1, 2 and 3 are correct
• B. 1 and 2 are correct
• C. 2 and 4 are correct
• D. 1 and 3 are correct

Answer 1

Answer: (C)

Cellular endosperm is found in $25\%$ 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.
