Indusium (Noun)
Meaning
A membrane enclosing and protecting the developing spores especially that covering the sori of a fern.
Classification
Nouns denoting plants.
Examples
- The indusium is a crucial structure that shields the fern spores as they mature and prepares them for dispersal.
- In the process of spore development, the indusium covers the sori and protects them from environmental stress and damage.
- The delicate indusium of the fern is responsible for maintaining a humid microclimate and regulating gas exchange as the spores grow.
- As the spores mature, the indusium typically dries and turns brown, signaling that the spores are ready for release.
- During this critical period of development, the indusium acts as a protective barrier that safeguards the fern spores from pathogens and dehydration.
