Q7.   In mosses the second gametophytic stage is leafy stage. Consider the following statements about leafy stage I. Leafy stage is produced from the secondary protonema as a lateral bud II. They consist of upright, slender axes bearing spirally arranged leaves III. They are attached to the soil through multicellular rhizoids IV. This leafy stage bears the sex organ Which of the statements given above are correct?
  •  I, II and III
