Definition

Noun: A thick-walled, asexual, and dormant spore formed by some fungi and algae, serving as a resting structure to survive unfavorable environmental conditions.

Usage

The term is used specifically in mycology (the study of fungi) and phycology (the study of algae) to describe a particular type of resilient, non-motile spore. It is a technical term.

Examples

• The fungus produced chlamydospores that allowed it to persist in the soil for many years.
• Under the microscope, the chlamydospore was easily identifiable by its thick, dark wall.
• The survival of the pathogen during the drought was attributed to its chlamydospores.

Advanced Usage

• Formation and Function: Chlamydospores are typically formed from hyphal cells. Their primary function is perennation, enabling the organism to survive periods of stress such as nutrient deficiency, desiccation, or extreme temperatures.
• In Plant Pathology: The term is frequently used in agricultural science when discussing soil-borne fungal pathogens (e.g., , ). Their chlamydospores make them difficult to eradicate from fields.

Variants and Related Words

• Chlamydospore is the standard noun form. The related adjective is chlamydosporic (e.g., chlamydosporic cells).
• Akinete: A similar thick-walled resting spore found in cyanobacteria and some algae.
• Resting Spore: A broader category that includes chlamydospores, oospores, and zygospores.

Synonyms

• Resting spore (in a general sense)
• Dormant spore
• Survival spore

Antonyms

• Zoospore (a motile, flagellated spore)
• Conidium (a thin-walled, asexual spore for dispersal, not primarily for dormancy)

Noun

1. thick-walled asexual resting spore of certain fungi and algae
