Find the next number: 1, 1, 2, 3, 5, 8, 13, ?
सही उत्तर: क) 21
This is the Fibonacci series, where each term is the sum of the two before it. 8 + 13 = 21.

Find the next number: 5, 11, 23, 47, 95, ?
सही उत्तर: क) 191
Each term is doubled and then 1 is added (5×2+1 = 11, 11×2+1 = 23, ...). So 95 × 2 + 1 = 191.

Find the next number: 2, 3, 5, 7, 11, 13, ?
सही उत्तर: घ) 17
The series lists consecutive prime numbers, and the prime after 13 is 17. 15 is tempting but it is divisible by 3 and 5.

Find the next number: 1, 4, 9, 16, 25, ?
सही उत्तर: ग) 36
The terms are squares of 1, 2, 3, 4, 5, so the next is 6² = 36. 49 is 7², which skips a step.

-
Find the next number: 3, 9, 27, 81, ?
सही उत्तर: ग) 243
Each term is multiplied by 3, so 81 × 3 = 243. 162 would come from doubling, which does not fit the earlier terms.

Polyembryony is commonly seen in:
सही उत्तर: ग) Citrus
In Citrus, nucellar cells develop into additional embryos, so a seed contains more than one embryo. Pea, wheat and mustard usually have a single embryo per seed.

Perisperm is:
सही उत्तर: क) Persistent nucellus in the seed
In seeds like black pepper and beet, part of the nucellus persists and is called perisperm. Endosperm, by contrast, develops from the primary endosperm nucleus.

The formation of seeds without fertilisation is called:
सही उत्तर: क) Apomixis
Apomixis produces seeds without fertilisation, as in some grasses and Asteraceae. Parthenocarpy produces seedless fruits without fertilisation.

-
The filiform apparatus, which guides the pollen tube into the embryo sac, is present in the:
सही उत्तर: क) Synergids
Synergids have cellular thickenings at the micropylar tip called the filiform apparatus. Antipodals lie at the chalazal end.

A typical (Polygonum type) embryo sac of angiosperms at maturity is:
सही उत्तर: क) 7-celled and 8-nucleate
It has three antipodals, two synergids, one egg and one central cell containing two polar nuclei: 7 cells, 8 nuclei. The central cell is binucleate, so cell number is less than nucleus number.
