Consider the following four statements and choose the correct option based on whether they are RIGHT or WRONG. (I) The sporophyte in liverworts is more elaborate than in mosses. (II) Salvinia is heterosporous. (III) The life cycle in all seed-bearing plants is diplontic. (IV) In Pinus , male and female cones are borne on different trees.

Step-by-step solution

Salvinia is a genera of Pteridophyte which produces two types of spores - micro and macro. Such type of spores are called heterosporous. The microspore gives rise to male plant and the megaspore forms the female plant. Liverworts, type of bryophytes, usually grow in moist shady habitats and its plant body is called as thalloid. The sporophyte of liverworts is differentiated into foot, setae and capsule. Mosses are another type of bryophyte whose sporophyte stage has similar three parts like liverworts but more elab
