Open in App
Solution
The correct option is A Heterocyst
A heterocyst is a differentiated cyanobacterial cell that carries out nitrogen fixation under aerobic conditions. They are formed in response to a lack of fixed nitrogen.Whereas an endospore is a dormant, tough, non-reproductive structure produced by a small number of bacteria from the Firmicute family. The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress.
An oospore is a thick-walled sexual spore that develops from a fertilized oosphere in some algae, fungi, and Oomycetes. In Oomycetes, oospores can also result from asexual reproduction, by apomixis.
Conidiospore - an asexually produced fungal spore formed on a conidiophore. Thus, the correct answer is option A.
