If the chromosome number in the leaf of Sphagnum is 10, what will be the chromosome number in the spores?
1 10
2 15
3 20
4 5
Explanation:
Leaf of Sphagnum is a part of gametophyte (n). Spore is formed after the reduction division of capsule cells of sporophyte (2n). Hence, the spore is haploid. Both leaf of Marchantia and spore will have same chromosome number.

Statement A : In mosses, after fertilization the zygote develops into sporophyte. Statement B : Sporophyte have foot, seta and capsule.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Zygote after multiple division develops into a multicellular sporophyte. The plant body is divided into foot, seta and capsule.

In Funaria, 30 chromosomes are present in seta then the number of chromosomes in gametophyte, rhizoids and capsule will be
1 30,30,30 respectively
2 15,30,30 respectively
3 15,15,30 respectively
4 30,30,15 respectively
Explanation:
Foot, seta, capsule are divisions of diploid sporophyte . Hence, cells of seta are diploid too. Seta = 2n = 30 , Gametophyte = n = 15, Rhizoids (gametophyte) = n = 15 , Capsule (sporophyte) = 2n = 30
