Sexual Reproduction in Flowering Plants 


Dear Readers,

NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions. About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus. Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams. The table below takes you directly to the respective topic where the in-depth article and the MCQs are available for an easy and productive learning experience. Prior to solving NEET question papers or practicing mock tests, you must ensure to study the basic concepts in NEET and practice a few sample questions related to this exam. Students will be covered for all their studies as the topics are available from basics to even the most advanced. .

Q1. Pollination by bats is called
  •  Anemophily
  •  Hydrophily
  •  Ornithophily
  •  None of these
Pollination by bats is called cheiropterophily.

Q2.Identify A to D in the following diagram

  •  A-Filament, B-Pollen sac, C-Pollen grain, D-Line of dehiscence
  •  A-Filament, B-Pollen sac, C-Line of dehiscence, D-Pollen grain
  •  A-Filament, B- Line of dehiscence, C- Pollen sac, D-Pollen grains
  •  A-Filament, B- Line of dehiscence, C- Pollen sac, D-Pollen grains

 (i) A typical angiospermic anther is a bilobed structures having two theca at each lobe 
 (ii) It is tetragonal in shape with 4 microsporangia located at each lobe in its corners
 (iii) Microsporangia develop into pollen sac, which produces pollen 


 1.A typical stamen 
 2.Three-dimensional cut section of an anther

Q3.  Nucellus forms which of the following parts of fruit?
  •  Seed coat
  •  Perisperm
  •  Seed
  •  Raphe
The post fertilization changes in the seeds are as follows: Ovule – Seed Ovary - Fruit Nucellus – Perisperm (a nutritive tissue) Integument – Seed coat

Q4. What does the filiform apparatus do at the entrance into ovule?
  •  It helps in the entry of pollen tube into a synergid
  •  It prevents entry of more than one pollen tube into the embryo sac
  •  It brings about opening of the pollen tube
  •  It guides pollen tube from a synergid to egg
Synergid cells are characterized by the presence of finger like projections called filiform apparatus attached to their upper wall at micropyler end. This filiform apparatus is known to attract and guide the pollen tube.

Q5.Which of the following is not true for double fertilization?
  •  Discovered by Nawaschin
  •  Male gamete and secondary nucleus fused to form endosperm nucleus
  •  endosperm nucleus is diploid
  •  endosperm nucleus nutrition to embryo
 Double fertilization is characteristic feature of angiosperms. It was discovered by S G Nawaschin in 1898. In double fertilization, one male gamete fused with ovum to form diploid zygote and the second male gamete fused with diploid secondary nucleus to form the triploid primary endosperm nucleus, which develops into endosperm. The endosperm provides nutrition to the developing embryo.

Q6. Entry of pollen tube with two male gametes and tube nucleus through micropyle, is
  •  Mesogamy
  •  Porogamy
  • Chalazogamy
  •  None of these
The chromosome number in gamete (n) of Ophioglossum (a tern) is 630, of rice is 12, of potato is 24, and of man is 23

Q7. Tapetum is found in
  •  Anther
  •  Microspore
  •   Male gametophyte
  •  Female gametophyte
Tapetum is the innermost layer of anther wall

Q8. Triple fusion in angiosperm is the fusion of second sperm with
  •  Antipodal cell and one synergid cell
  •  Two antipodal cells
  •  Two synergid cells
  •  Two polar nuclei
Triple fusion in angiosperm is the fusion of second sperm with two polar nuclei or the secondary nucleus which results in the formation of a triploid Primary Endosperm Nucleus (PEN).

Q9. Microsporangium produces
  •  Male gametes
  •  Female gametes
  •  Pollen
  •  Both (a) and (c)
Pollens contain male gametes hence both the terms are used in angiosperms during sexual reproduction

Q10. In nature, cleistogamous flowers are
  •  Self-pollinated
  •   insect-pollinated
  •   Wind-pollinated
  • Bird-pollinated
Autogamy is a type of self-pollination. which occurs between anther and stigma of same flower. Cleistogamous flowers, remain closed so that only self pollination occurs. Examples include Commelina, groundnut, balsam, Viola, Oxalis.
