If one set of chromosomes for a given plant is represented as N; in case of double fertilization, the zygote and the endosperm nucleus of a diploid plant would have how many sets of chromosomes respectively?

If one set of chromosomes for a given plant is represented as N; in case of double fertilization, the zygote and the endosperm nucleus of a diploid plant would have how many sets of chromosomes respectively? Correct Answer 2 N and 3 N

Flowering plants show double fertilization in which two male gametes fuse with one female gamete.

  • In this case, while one male gamete fertilizes the egg to form a zygote, the other fuses with two polar nuclei resulting in the formation of an endosperm.
  • Double fertilization stimulates the plant resulting in the development of ovules into seed and ovary into fruit.
  • The zygote will have 2N chromosomes.
  • The endosperm nucleus will have 3N sets of chromosomes after double fertilization.

Consider the following statements and choose the correct answer:
1. For the development of viable seeds the double fertilization is very necessary
2. The net result of double fertilization is the formation of endosperm from the triploid nucleus
3. In Angiosperms very free nuclear divisions take place as in Gymnosperms
4. The endosperm nucleus has both maternal and paternal characters showing physiological importance like hybrid vigour
A words is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given tow matrices. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix – II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example ‘K’ can be represented by 40, 33 etc and ‘Z’ can be represented by 67, 59 etc. Similarly, you have to identify the set for the word ‘TIRE’ Matrix I   0 1 2 3 4 1 I D I L E 2 D I H F I 3 H C E K B 4 K A B G M   Matrix II   5 6 7 8 9 5 P U Z R Z 6 O N Z T O 7 R X S R X 8 R Q V O P 9 R P Q Z T
