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.   Continued self-pollination results in
  •  Inbreeding depression
  •  Out breeding depression
  •  Hybrid vigour
  •  Better result in offsprings
(a) Continued self breeding means there is continuation of genetic material to the progeny from the parents. As they are the product of same genotype of same plant. This leads to less productivity called inbreeding depression

Q2.   Polyembryony is a type of
  •  Apomixis
  •  Fertilization
  •  Fusion
  •  Embryogenesis
(d) Polyembryony is the formation of more than one embryo so it is the type of embryogenesis


  •  Air pollination
  •  Anemophily
  •  Water pollination
  •  Hybridization
(a) Presence of feathery and exposed stigma are the characters of wind-pollinated plant

Q4.   Megasporogenesis is
  •  Formation of fruit
  •  Formation of seeds
  •  Formation of megaspores
  •  Both (b) and (c)
(c) Megaspore is commonly called as ovum. These terms are generally used in case of plants and animals. The process of formation of ova or megaspore called oogenesis or megasporogenesis respectively

Q5.   Pollen kit material is secreted by
  •  Tapetum
  •  Endothecium
  •  Epidermis
  •  Endodermis
(a) In insect pollinated plants, a sticky material is deposited on the pollen grains known as ‘pollen kit material’, which is secreted by the tapetum.

Q6.   First three layers of microsporangium which does the function of protection are
  •  Epidermis, endothecium, middle layer
  •  Epidermis, mesocarp, endocarp
  •  Epidermis, middle layer, endothecium
  •  Epidermis, endocarp, mesocarp
(c) Epidermis middle layer, endothecium, they are present outerly and have the function of protection. But sometime endothecium does the function of nourishment

Q7.   Fibrous thickenings of hygroscopic nature are found in which part of the anther wall?
  •  Epidermis
  •  Endothecium
  •  Middle layers
  •  Tapetum
(b) Endothecium is an unilayer of radially elongated cells occurs between the epidermis and middle layers of an angiospermic anther wall. Cells of endothecium have fibrous thickening in their cell walls due to which they become hygroscopic and thus, help in the dehiscence of mature anther.

Q8.   Albuminous seed
  •  Has no endosperm
  •  Has thick cotyledons
  •  Have food storage in cotyledons
  •  Both (b) and (c)
(d) Albuminous seed retain a part of endosperm as it is not completely used up during embryonic development, e.g., Wheat, maize, barley, castor, sunflower. Their cotyledons are fleshy and thick as compared to the non-albuminous seed

Q9.   The outermost layer of maize endosperm is known as
  •  Perisperm
  •  aleurone
  •  Tapetum
  •  endothelium
(b) In cereals, one of few outer layers of endosperm are thick-walled with dense cytoplasm having pits. These are mainly filled with aleurone grains (highly protein rich) and hence, called aleurone tissue or aleurone layer.

Q10.   Which of the following statement is/are true I. Endothecium lies behind epidermis II. Fusion of egg with male gamete is called apogamy. III. Synergids are haploid IV. The point at which funicle touches the ovule is raphe.
  •  II and IV only
  •  I and II only
  •  I and IV only
  •  I and III only
(d) The fusion of male and female gametes is called fertilization, while the mode of formation of new individuals from specialized or non-specialized parts of the parent without meiosis or fusion of gametes is called the asexual reproduction. Apogamy is a type of asexual reproduction, in which sporophyte is directly formed from a gametophyte without involving the formation and fusion of gmetes. Funicle is the stalk of ovule. The point of attachment to the body of ovule with the funiculus is known as hilum. A raphe or longitudinal ridge is formed by the fusion of funiculus with the body of ovule.
