Question

Structures for dispersal of spores in Bryophyta are

• A. Elaters
• B. Pseudoelaters
• C. Peristomeal teeth
• D. All of the above

Answer 1

The correct option is D All of the above

A- An elater is a cell that changes shape in response to the changes in moisture in the environment. In many plants they do not have seeds, they function in dispersing the spores in different locations.

B- They surround the spores and help propel them further in the environment, they are basically single-celled in structure.

C- In mosses, the peristome is a specialized structure in the sporangium that allows for gradual spore discharge, instead of releasing them all at once.

So the correct option is 'All of the above'.
