Q. Choose the correct statement about liverworts I. In liverworts sexual reproduction occurs by the fusion of antherozoids and egg, which are produced in anthridium and archegonium, respectively II. Both male and female sex organs may be present on same thalli or different thalli III. Zygote give rise to sporophyte, which is differentiated into food, seta and capsule IV. Some cells of capsule undergoes meiosis and give rise to haploid spores

A) I, II and III
B) II, III and IV
C) I, III and IV
D) I, II, III and IV
Explanation

All the statements are correct. Sexual reproduction occurs by the formation of sex organs born on special branches. The male antheridia are produced on antheridiophore and the female reproductive organs are ‘archegonia’. They are borne on special stalked structures called archegoniophore. Both male and female sex organ may be present on same thalli or different thalli. After fertilisation, the egg becomes zygote, which grow to form sporophyte. It is differentiated into foot, seta and capsule. Inside the capsule, the diploid spore mother cells divide by meiosis and produce haploid spores. These spores germinate to form free-living gametophytes
