  1. Maheshwari
  2. Yuho
  3. Stanley
  4. Nageli

Answer: 1. Maheshwari

The publication of the late Professor P. Maheshwari’s text, An Introduction to the Embryology of Angiosperms, serves as valuable guide for students and a rich source for research workers.

Question 2. Which of the following is false in angiosperms?

  1. Egg cell – Haploid
  2. Megaspore – Diploid
  3. Pollen grain – Haploid
  4. Synergid – Haploid
  5.  Endosperm – Triploid

Answer: 2. Megaspore – Diploid

Option is false and can be corrected as Megaspore mother cell (2n) undergoes reduction division to form 4 haploid (n) megaspores by the process called megasporogenesis.  Thus, megaspore is haploid (n).

Rest options are true in angiosperms.

Question 3. If the haploid number in a flowering plant is 14. What shall be the number of chromosomes in integuments, antipodal cells, embryo, endosperm, and nucellus, respectively?

  1. 14, 28, 7, 42, 21
  2. 7, 14, 42, 28, 14
  3. 28, 14, 28, 42, 28
  4. 42, 28, 14, 28, 14

Answer: 3. 28, 14, 28, 42, 28

Integument is a diploid cell 2n = 2 ×14 = 28 Antipodal cells are haploid (n) = 14 Embryo is diploid (2n) = 2 × 14 = 28 Endosperm is triploid (3n) = 3 × 14 = 42 Nucellus is diploid (2n) = 2 × 14 = 28

Question 4. Match Column 1 with Column 2 and choose the correct option from the codes given below

NEET Biology Miscellaneous.

Answer: 5. A–4, B–5, C–1, D–2, E–3

Question 5. Which of the following statement(s) is/are true?

  1. Endothecium lies behind epidermis.
  2. Fusion of egg with male gamete is called apogamy.
  3. Synergids are haploid.
  4. The point at which funicle touches the ovule is raphe.

Choose the correct answer

  1. 2 and 4 only
  2. 1 and 4 only
  3. 1 and 2 only
  4. 1 and 3 only
  5. None of these

Answer:  4. 1 and 3 only

  • Statements 1 and 3 are true whereas 2 and 4 are false. Incorrect statements can be corrected as Apogamy is the development of a plant without the union of gametes, development of a sporophyte from a gametophyte without fertilisation.
  • Fusion of egg with male gamete is called syngamy. The point at which funicle touches the ovule is hilum.

Question 6. Study the following statements and select the correct option.

  1. Tapetum nourishes the developing pollen grains.
  2. Hilum represents the junction between ovule and funicle.
  3. In aquatic plants, such as water hyacinth and water lily, pollination is by water.
  4. The primary endosperm nucleus is triploid.

Choose the correct answer 

  1. 1 and 2 are correct, but 3 and 4 are incorrect
  2. 1, 2, and 4 are correct, but 3 is incorrect
  3. 2, 3, and 4 are correct, but 1 is incorrect
  4. 1 and 4 are correct, but 2 and 3 are incorrect
  5.  2 and 4 are correct, but 1 and 3 are incorrect

Answer: 2. 1, 2, and 4 are correct, but 3 is incorrect

All given statements are correct except 3. Incorrect statement can be corrected as In water hyacinth and lily, the pollination agency is not water but insects. Although they are aquatic plants, it is not necessary that all aquatic plants are pollinated by water.

Question 7. Consider the following statements with respect to flowering plants.

  1. Pollen grains represent the male gametes.
  2. The functional megaspore develops into the embryo sac represents the female gamete.
  3. Transfer of pollen grains from anther to the stigma of different plants is known as xenogamy.
  4. Transfer of pollen grains from anther to the stigma of another flower of the same plant is known as geitonogamy.

Of the above statements

  1. 1 and 2 alone are correct
  2. 1 and 3 alone are correct
  3. 2 and 4 alone are correct
  4. 3 and 4 alone are correct

Answer: 4. 3 and 4 alone are correct

  • Statements 3 and 4 are correct whereas 1 and 2 are incorrect with respect to flowering plants. Incorrect statements can be corrected as
  • Pollen grains represents male gametophyte that carry male gametes. The functional megaspore develops into embryo sac that represents female gametophyte.

Question 8. A botanist collected some fruits with hook-like spines and when the seeds of the same have been germinated, they turned out to be asteraceous taxa, bearing sepalous and wind-pollinated flowers. The fruit he collected was of

  1. Xanthium strumarium
  2. Lactuca sat4a
  3. Carthamus tinctorius
  4. Sphaeranthus indica

Answer: 1. Xanthium strumarium

  • The fruits collected by botanist belongs to Xanthium strumarium, which are known as rough cocklebur and are a species of annual plants of family–Asteraceae.
  • During flowering, they give rise to an asepalous flower which later turns into fruits with hook-like spines.
