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. Parthenium or carrot grass is imported with
  •  Wheat
  •  Grass
  •  Rise
  •  Maize
Parthenium is also called congress grass, which came with wheat variety imported from Maxico. Now, it is a serious weed of wheat and produce large number of pollen grains which causes bronchial allergies

Q2.The terminal structure of stamen is called
  •  Pollen
  •  Filament
  •  Anther
  •  All of these
Terminal structure of stamen is called anther, which contain pollen grain (male gametophyte). Pollen grains are haploid in nature.

Q3.   For good growth of pollen tube, necessary element is
  •  Ca
  •  B
  •  Mg
  •  Mo
Boron (B) is an essential micro-element or trace element, which is required for pollen germination, good growth of pollen tube and fertilization.

Q4. Selaginella and Salvinia considered to represent a significant step towards evolution of seed habit because
  •  Female gametophyte is free and gets dispersed like seed
  •  Female gametophyte lacks archegonia
  •  Megaspore possess endosperm and embryo surrounded by seed coat
  •  Embryo develops in female gametophyte which is retained on the parent sporophyte
Development of embryo in female parent body is a major step in seed development because in this there is no need of water. In lower plants, water is always needed for fertilization. So, it is the revolutionary step.

Q5.Pollen grains have ability to tolerate extreme temperatures because of the presence of
  •  Sporopollenin
  •  Suberin
  •  Cubin
  •  Callose
Pollen grains are generally 25-50 μm in diameter. Pollen grains have two main layers 
(i) Outer Layer It is also called exine. It is made up of sporopollenin. It is hard and protective in nature. Due to sporopollenin pollen can with stand extreme temperatures. 
(ii) Inner layer It is also called intine. It is made up of cellulose and pectin. It is very thin as compared to the outer layer .

Q6. Identify A to E in the following diagram 

  •  A-Tapetum, B-Microspore mother cell, C-Middle layer, D-Endothecium, E-Epidermis
  •  A- Epidermis, B- Middle layer, C- Microspore mother cell, D- Tapetum, E- Endothecium
  • A- Middle layer, B- Epidermis, C- Tapetum, D- Microspore mother cell, E- Endothecium
  •  A- Epidermis, B- Endothecium, C-Middle layer, D- Microspore mother cell, E- Tapetum
Microsporangium is mainly surrounded by four layers/wall, i.e., Epidermis, endothecium, middle layer and tapetuem (i) Epidermis endothecium and middle layer help in protection and dehiscence of anther from pollen (ii) Tapetum nourishes the developing pollen grain.

Q7. What would be the number of chromosomes of the aleurone cell of a plant with 42 chromosomes in its root tip cells?
  •  63
  •  84
  •  21
  •  42
The outermost cell later of the endosperm (3n) of seed is called aleurone layer. Since, the cells of aleurone layer are triploid, the number of chromosomes would be = 63, as root tip cells (2n) has 42 chromosomes.

Q8. Synergids are
  •  Haploid
  •  Diploid
  •  Triploid
  •  Tetraploid
In embryo sac-synergids, egg cells, antipodal cells all are haploid because they are formed by mitotic division in haploid megaspore cell.

Q9. Wind pollinated and water pollinated plants
  •  Are colourful
  •  Are non-colourful
  •  Are small in size
  •  Produce nector
Because wind pollinated and water pollinated plants do not need any biotic agency for pollination so no need for fragrance. Nector and colourfulness. Generally, wind-pollinated plant are big in size due to producing more pollen and have exposed stigma for easily capturing pollens.

Q10.  Plants of which one of the following groups of genera are pollinated by the same agency?
  •  Triticum, mussanda, zea mays
  •  Kadam, cannabis
  •  Salvia, calotropis
  • Salvia, pinus, ophrys
Salvia, Calotropi sand Rafflesia all are insect pollinating flowers.
