Biology MCQs for NEET Chapter – Sexual Reproduction in Flowering Plants
Q.1. One of the most resistant biological material is
(a) lignin
(b) hemicellulose
(c) lignocellulose
(d) sporopollenin
Answer
Answer:(d) Each pollen has two layered wall. The outer layer is thick, tough, cuticularised called exine which is composed of a material called “sporopollenin”. It is highly resistant to biological and physical decomposition, due to which pollens are preserved for a long time in fossils.
Q.2. Female gametophyte of angiosperms is represented by
(a) Ovule
(b) Megaspore mother cell
(c) Embryo sac
(d) Nucellus
Answer
Answer:(c) Embryo sac is 7-celled structure. There is a large central cell with two polar nuclei, egg apparatus with egg cell and 2 synergids present at micropylar end and its chalazal end, 3 antipodal cells are present.
Q.3. When funiculum, chalaza, and micropyle lie in one straight line, then ovule is called –
(a) Amphitropous
(b) Orthotropous
(c) Campylotropous
(d) Anatropous
Answer
Answer:(b)
Q.4. Which of the following pair has haploid structures?
(a) Nucellus and antipodal cells
(b) Antipodal cells and egg cell
(c) Antipodal cells and megaspore mother cell
(d) Nucellus and primary endosperm nucleus

Answer
Answer:(c)
Q.8. Entry of pollen tube through micropyle is
(a) Chalazogamy
(b) Mesogamy
(c) Porogamy
(d) Pseudogamy
Answer
Answer:(c) In porogamy the tip of pollen tube enters the micropyle, pushes through the nucellar tissue & finally pierces the eggapparatus end of the embryo sac. If pollen tube enters through the chalazal side it is called chalazogamy & if it enters laterally it is called mesogamy.

(a) Caryopsis
(b) Cypsela
(c) Berry
(d) Cremocarp
Answer
Answer:(b) Dry indehiscent single-seeded fruit formed from bicarpellary syncarpous inferior ovary is cypsela. Cypsela is also called inferior, false or pseudocarpic achene, the thin fruit wall (developed from pericarp and thalamus)is attached to the seed at one point but the fruits develops from an inferior, unilocular and uniovuled ovary, e.g., sunflower, marigold. Some cypsela develop pappus for dispersal e.g. Sonchus, Taraxacum.

X | Y
(a) Funicle Hilum
(b) Hilum Funicle
(c) Funicle Micropyle

Q.15. Unisexuality of flowers prevants
(a) autogamy, but not geitonogamy
(b) both geitonogamy and xenogamy
(c) geitonogamy, but not xenogamy
(d) autogamy and geitonogamy
Answer
Answer:(a) Unisexuality of flowers prevents autogamy, but not geitonogamy. In self fertilisation , the male and female gametes are derived from the same individual. Among plants, self fertilization also called autogamy is common in many cultivated species, eg., wheat and oats. However, self fertilization is a form of inbreeding and does not allow for the mixing of genetic material; if it occurs over a number of generations it will result in offspring being less vigorous and productive than those resulting from cross fertilization.
Q.16. Which one of the following represents an ovule, where the embryo sac becomes horse-shoe shaped and the funiculus and micropyle are close to each other?
(a) Amphitropous
(b) Circinotropous
(c) Atropous
(d) Anotropous
Answer
Answer:(a) Amphitropous : Both body of ovule and embryo sac are curved. The embryo sac assumes horse-shoe shape. e.g. Papaveraceae.

(a) haploid
(b) triploid
(c) tetraploid
(d) pentaploid
