Maharashtra MSBSHSE HSC Biology (code 56) is a Class 12 public-exam science subject of about 3 hours theory (commonly 70+30 with practical) with ~35% pass floor, covering Balbharati themes from reproduction through biotech and ecology — not a pure MCQ board paper. This free 2026 bank is an English MCQ study adaptation for concept and diagram fluency.

1Double fertilisation in angiosperms involves fusion of one male gamete with the egg and the other male gamete with the:
A.Synergids only
B.Antipodals only
C.Two polar nuclei (secondary nucleus)
D.Nucellus alone
Explanation: In angiosperms, one male gamete fuses with the egg (syngamy) and the other fuses with the two polar nuclei to form primary endosperm nucleus — double fertilisation, a hallmark of flowering plants in Balbharati Std XII Biology.
2Transfer of pollen grains from the anther to the stigma of the same flower is called:
A.Xenogamy
B.Geitonogamy
C.Autogamy
D.Apomixis
Explanation: Autogamy is self-pollination within the same flower. Geitonogamy is between flowers of the same plant; xenogamy is between different plants.
3The residual, persistent nucellus in some seeds (e.g. black pepper, beet) is called:
A.Endosperm
B.Perisperm
C.Coleoptile
D.Scutellum
Explanation: When nucellus remains in the mature seed, it is termed perisperm and may store food, as in black pepper and beet.
4In a typical angiosperm embryo sac, the egg apparatus consists of:
A.Two synergids and one egg cell
B.Three antipodals only
C.Two polar nuclei only
D.One synergid and two eggs
Explanation: The egg apparatus at the micropylar end comprises one egg cell and two synergids; three antipodals lie at the chalazal end and two polar nuclei in the centre.
5Which device promotes cross-pollination by ensuring pollen and stigma of the same flower mature at different times?
A.Cleistogamy
B.Dichogamy (protandry or protogyny)
C.Homogamy only
D.Apomixis
Explanation: Dichogamy — protandry (anthers mature first) or protogyny (stigma matures first) — is a temporal barrier that favours outbreeding.
6Microsporogenesis is the process of formation of:
A.Megaspore mother cells only
B.Microspores from microspore mother cells by meiosis
C.Embryo sac from megaspore
D.Endosperm without fertilisation
Explanation: Microspore mother cells (2n) undergo meiosis to form haploid microspores that develop into pollen grains — microsporogenesis.
7In many orchids, the tiny seeds lack endosperm. Seedling establishment often depends on a symbiotic association with:
A.Cyanobacteria only in roots
B.Mycorrhizal fungi
C.Rhizobium nodules on leaves
D.Azolla floating free only
Explanation: Orchid seeds are minute and often lack stored food; association with mycorrhizal fungi supplies nutrients for germination and early growth.
8In human males, spermatogenesis is completed in the:
A.Seminal vesicles
B.Seminiferous tubules of the testes
C.Epididymis lumen only as meiosis
D.Prostate gland
Explanation: Spermatogenesis occurs in the seminiferous tubules. Sperm mature further and are stored in the epididymis, but meiotic production is tubular.
9The hormone primarily responsible for ovulation in humans is a surge of:
A.Prolactin
B.FSH alone without LH
C.LH (luteinising hormone)
D.Oxytocin only
Explanation: A mid-cycle LH surge triggers ovulation of the mature Graafian follicle; FSH mainly drives follicular growth earlier in the cycle.
10Fertilisation in humans normally occurs in the:
A.Uterine cavity only
B.Ampullary region of the fallopian tube
C.Cervix
D.Vagina
Explanation: Sperm meet the secondary oocyte in the ampullary region of the oviduct (fallopian tube), where fertilisation typically occurs.
