Reproduction in Lower and Higher Plants MCQ with Answers PDF
Reproduction in Lower and Higher Plants MCQ: Reproduction is the process by which new individuals of a species are created from pre existing ones. Angiosperms are flowering plants in which ovules are present within ovary. Reproduction is of two types namely asexual and sexual reproduction. The reproduction which do not involve meiosis and fertilization is known as apomixis or asexual reproduction. The reproduction in which there is union of gametes is called sexual reproduction.

Reproduction in Lower and Higher Plants MCQ with Answers
1. Insect pollinated flowers usually posses____________
a. Sticky pollens with rough surface
b. Large quantities of pollens
c. Dry pollens with smooth surface
d. Light coloured pollens
Answer: a
Explanation: Insect-pollinated flowers usually possess sticky and heavy pollens with a rough surface that allow them to stick to insects easily. The pollen grains are also in small quantities, because it is very likely that insects will enter another flower, and the pollen grains would have a higher chance of landing on the stigma. That’s why there is no need of pollen grains in large quantities.

2. In ovule, meiosis occurs in______________
a. Integument
b. Nucellus
c. Megaspore
d. Megaspore mother cell
Answer: d
Explanation: In the ovule Megaspore mother cell/megasporocyte which divides by meiosis to form four haploid megaspores. Thus, in ovule meiosis occurs in the megasporocyte / Megaspore Mother Cell

3. The ploidy level is NOT the same in____________
a. Integuments and nucellus
b. Root tip and shoot tip
c. Secondary nucleus and endosperm
d. Antipodals and synergids
Answer: c
Explanation: Integuguments and nucellus carry 2n respectively. Root tip & shoot tip also carry 2n respectively. Antipodals & synergids carry only n respectively. While secondary nucleus carry 2n & endosperm carry 3n. That’s why the ploidy level is NOT same in secondary nucleus and endosperm.
4. Which of the following types require pollinator but result is genetically similar to autogamy?
a. Geitonogamy
b. Xenogamy
c. Apogamy
d. Cleistogamy
Answer: a
Explanation: Transfer of pollen from an anther of one flower to a stigma of another flower on the same plant is called as geitonogamy. Although geitonogamy is functionally cross-pollination involving a pollinating agent, genetically it is similar to autogamy since the pollen grains come from the same plant.

6. If diploid chromosome number in a flowering plant is 12, then which one of the following will have 6 chromosomes?
a. Endosperm
b. Leaf cells
c. Cotyledons
d. Synergids
Answer: d
Explanation: Synergids are formed by megaspore which is a haploid structure. Thus synergids are haploid and possess 6 chromosomes. So, the correct answer is ‘synergids’.

7. In angiosperms, endosperm is formed by/ due to___________
a. Free nuclear divisions of megaspore
b. polar nuclei
c. polar nuclei and male gamete
d. synergids and male gamete
Answer: c
Explanation: Endosperm is formed when the two sperm nuclei inside a pollen grain reach the interior of a female gametophyte and one the sperm is fused with polar nuclei and forms Endosperm. That’s why the correct answer is ‘c’ polar nuclei and male gamete.
8. Point out the odd one____________
a. Nucellus
b. Embryo sac
c. Micropyle
d. Pollen grain
Answer: d
Explanation: Pollen grain is odd one among all the other three. Pollen grain in a male gametophytic structure. Whereas all the other three are found inside ovule, (nucellus, micropyle and embryo sac.)

1. Central body of ovule is called_______
a) hilum
b)nucellus
c) funicle
d) chalaza
Answer: b) nucellus
Explanation: The nucellus is the central part of the ovule which houses the female gametophyte or embryo sac.
2. Movement of non motile male gamete upto the female gamete is known as__________
a) siphonogamy
b) triple fusion
c) syngamy
d) porogamy
Answer: a) siphonogamy
Explanation: Siphonogamy refers to the process by which the non-motile male gamete (sperm cell) is transferred to the female gamete (egg cell) through a pollen tube.
3. Embryo sac is_____________
a) megasporangium
b) megaspore
c) female gamete
d) female gametophyte
Answer: d) female gametophyte
Explanation: The embryo sac is the female gametophyte in angiosperms, containing the egg cell and other accessory cells necessary for fertilization.
4. Most common type of ovule in angiosperms is________
a) orthotropous
b) anatropous
c) campylotropous
d) amphitropous
Answer: b) anatropous
Explanation: Anatropous ovules are the most common type in angiosperms, where the ovule is inverted, with the micropyle facing the funicle.
5. For formation of 50 seeds, how many minimum meiotic divisions are necessary ?
a) 50
b) 63
c) 25
d) 75
Answer: b) 63
Explanation: Each seed originates from a fertilized ovule, which requires one meiotic division to form a megaspore, and then two more divisions to form the egg cell. So, 50 seeds would require 50 fertilized ovules, which in turn need 63 meiotic divisions (50 for megaspore formation and 13 for egg cell formation).
6. In bisexual flowers, maturation of gynoecium before androecium is known as__________
a) protandry
b)gynandry
c) protogyny
d) dicliny
Answer: c) protogyny
Explanation: Protogyny refers to the maturation of the female reproductive organs (gynoecium) before the male reproductive organs (androecium) in bisexual flowers.
7. If the number of chromosomes in an endosperm cell is 27, what will be the chromo- some number in the definitive nucleus?
a) 9
b) 18
c) 27
d) 36
Answer: b) 18
Explanation: In endosperm formation, the number of chromosomes in the definitive nucleus is usually half that of the endosperm cell. So, if the endosperm cell has 27 chromosomes, the definitive nucleus would have half of that, which is 18 chromosomes.
8. Lever mechanisim of pollination is observed in_________
a) Salvia
b) Jasmine
c) Bougainvillea
d) Butea
Answer: a) Salvia
Explanation: Salvia exhibits lever mechanism of pollination, where the visiting insect depresses the lower lip of the flower, causing the stamens to touch its body and deposit pollen.
9. Identify the wrong one from the following : In an orthotropous ovule_________
a) the micropyle and chalaza are in one
straight line
b) the micropyle and funicle are in one
straight line
c) the funicle, embryo sac, micropyle and
style are all in one straight line
d) the funicle, chalaza, embryo sac, micropyleare not in one straight line
Answer: c) the funicle, embryo sac, micropyle and style are all in one straight line
Explanation: In an orthotropous ovule, the micropyle and chalaza are in one straight line, but the funicle, embryo sac, micropyle, and style are not in one straight line.
10. Type of pollination in Vallisneria is_________
a) anemophily
b) hydrophily
c) omithophily
d) entomophily
Answer: b) hydrophily
Explanation: Vallisneria undergoes hydrophily, a type of pollination where pollination occurs by means of water.
11. The product of syngamy leads to the formation of_________
a) endosperm
b) embryo
c) perisperm
d) cotyledon
Answer: b) embryo
Explanation: Syngamy is the fusion of male and female gametes, resulting in the formation of the zygote, which develops into the embryo.
12. In angiosperms, fertilization occurs________
a) in the stamen
b) when the male gamete fuses with an egg cell
c) on the outer surface of the ovary
d) some time after pollination
Answer: b) when the male gamete fuses with an egg cell
Explanation: Fertilization in angiosperms occurs when the male gamete (sperm cell) fuses with the egg cell inside the embryo sac.
13. In Helobial type of endosperm development__________
a) first only nuclei divides
b) only first division is followed by cytokinesis
c) every nuclei division accompained by
cytokinesis
d) only second division is followed by auxin
Answer: b) only first division is followed by cytokinesis
Explanation: In Helobial type of endosperm development, only the first division of the primary endosperm nucleus is followed by cytokinesis, resulting in the formation of a basal and an apical cell.
14. Entomophilous flowers usually shows modified structures like________
a) tiny flowers with white colour
b) dry pollens with smooth surface
c) light weight, bright coloured pollen
d) sticky pollen with rough surface
Answer: d) sticky pollen with rough surface
Explanation: Entomophilous flowers often have sticky pollen with a rough surface, which helps in adhering to the bodies of insects for pollination.
