Elaters are specialized cells in bryophytes that twist and turn in response to changes in moisture. This twisting motion helps in seed dispersal by aiding in the release of spores from the sporangium when it is dry and then coiling back to protect the spores when it is wet. This mechanism increases the chances of spore dispersal in suitable conditions for germination.

Are elaters in bryophytes haploid or diploid?

Elaters of marchantia are haploid?
Yes, elaters of Marchantia are haploid, serving to disperse spores in liverworts. They are specialized cells involved in spore dispersal, expanding and contracting to aid in spore release.

What is the function of elater in the capsule Marchantia sp?
Elaters in the capsule of Marchantia sp. are responsible for aiding in seed dispersal. They help in the dispersal of spores by expanding and contracting in response to changes in humidity, effectively releasing spores into the environment.

What is calyptra in botany?
In botany, a calyptra is a protective covering or cap that encloses the developing capsule of mosses. It is derived from the archegonium, which is the female reproductive organ of mosses. The calyptra is shed as the capsule matures and the spores are released.
