Consider the following statements, mark the incorrect-a)Multicellular ...
Mosses. In mosses, as in liverworts and hornworts, the leafy shoots belong to the gametophytic phase and produce sex organs when they mature. The leafy shoots (often called gametophores, because they bear the sex organs) arise from a preliminary phase called the protonema, the direct product of spore germination.

Consider the following statements, mark the incorrect-a)Multicellular ...
Incorrect Statement: Protonema stage of mosses can bear sex organ
Explanation:
Protonema is a thread-like structure that is formed during the germination of the spore of moss. It is the first stage in the life cycle of mosses. The protonema is formed from the germinating spore and it gives rise to the gametophyte of the moss.
The protonema does not bear the sex organs in mosses. The sex organs in mosses are formed on the gametophyte plant. The male sex organ is called antheridium and it is formed at the tip of the male gametophyte plant. The female sex organ is called archegonium and it is formed at the tip of the female gametophyte plant.
Hence, the correct statement is that the male and female organs in mosses are present at the tip of their respective branches.
Corrected Statements:
a) Multicellular sex organs are present in all higher plants and in bryophytes also
b) Leafs in liverworts are present in two rows on stem-like structure
c) Male and female organs in mosses are present in the tip of their respective branches.
