Question

Match column I with column II and select the correct option.

Column I	Column II
Name of the organism	Haploid chromosome number in gametes
A. Ophioglossum	1. 23
B. Rice	2. 24
C. Potato	3. 12
D. Man	4. 630

(A) A-1, B-2, C-3, D-4
(B) A-2, B-3, C-4, D-1
(C) A-3, B-4, C-2, D-1
(D) A-4, B-3, C-2, D-1
(E) A-4, B-3, C-1, D-2

Answer 1

Hint: In any given asexually reproducing species, the chromosome number is always the same. The number of chromosomes inside the body (somatic) cells commonly is diploid (2n; a couple of every chromosome in sexually reproducing living beings,), double the haploid (1n) number found in the sex cells, or gametes.

Complete step by step answer
-Here, 2n= diploid and n= Haploid.
- Ophioglossum can contain 1260 ( 2n) no of the chromosome. So, n = 630
-Rice, 2n=24chromosome So,n= 12
-Potato,2n= 48 chromosome So, n=24
-Man, 2n= 46 chromosome So, n=23

Additional information
Haploid portrays a cell that contains one bunch of chromosomes. The term haploid additionally can solicit the number from chromosomes in egg or sperm cells, which likewise are called gametes. In people, gametes are haploid cells that contain 23 chromosomes, every one of which a 1 of a chromosome pair that exists in diploid cells. The number of chromosomes during a single set is represented as n, which is additionally called the haploid number. In humans, n = 23.
An organism with any multiple of the diploid number of chromosomes is claimed to be polyploid. Polyploidy may be a normal evolutionary strategy among many plant groups but appears to be quite rare in animals. Instances of polyploid plants and creatures are the potato (Solanum tuberosum), the African mauled frog (Xenopus laevis), and along these lines the fields viscacha rodent (Tympanoctomys barrerae; likewise called red viscacha rodent).

So the correct answer is ‘D’.

Note: Gametes contain a large portion of the chromosomes contained in ordinary diploid cells of the body, which likewise are alluded to as substantial cells. Haploid gametes are produced during meiosis, which may be a sort of cellular division that reduces the number of chromosomes during a parent diploid cell by half. A few living beings, similar to green growth, have haploid bits of their life cycle. Different creatures, similar to male ants, live as haploid life forms for an incredible duration cycle.
