Question

Choose the correct statement from the following about bryophytes.

• A. Gametophyte of bryophytes are diploid, independent and have sex organs.
• B. Male and female sex organ is archegonium and antheridium, respectively.
• C. Sex organs arise on a stalk and are covered by a layer of sterile cells.
• D. Sex organs are unicellular like algae.

Answer 1

The correct option is C Sex organs arise on a stalk and are covered by a layer of sterile cells.

Bryophytes are multicellular, thalloid plants devoid of vascular tissues. They have haplo-diplontic life cycle which means that the gametophytic phase is prominent in their life cycle. Both the sporophytic and gametophytic generations are multicellular. The gametophyte of bryophytes is independent, haploid and have sex organs. The sex organs are multicellular, unlike algae. They arise on a stalk and are covered by a layer of sterile cells known as the jacket.
The male and female sex organ is known as antheridium and archegonium, respectively. They produce gametes.
