Question

The asexual spores of fungi produced at terminal ends or intercalary places during extremely unfavourable conditions are
(a)Zoospores
(b)Chlamydospores
(c)Conidia
(d)Oidia

Answer 1

Hint: These are small, spherical, thick-walled, dark-coloured, vegetative spores having a smooth surface. They are having condensed cytoplasm that forms within hyphae or at hyphal tips.

Complete answer:
The chlamydospores are asexual spores of fungi produced at terminal ends or intercalary places during extremely unfavourable conditions. These are also known as resting spores of several kinds of fungi and they are formed by the rounding of a cell or cells. Chlamydospores are having condensed cytoplasm that forms within hyphae or at hyphal tips. This stage of life survives in unfavourable conditions, such as dry or hot seasons and when the condition becomes favourable they germinate.

Additional Information:
-These are multicellular and product of asexual reproduction.
-In the septae between the cells, the pores are connected with the cell.
-The Chlamydospores are intercalary or terminal in position.
-They remain viable for several years until the unfavourable condition remains.
-As soon as the favourable condition appears they germinate to give rise to the same type of mycelium.
-Zoospores are also known as swarm spores.
-These are asexual spores having flagella for locomotion.
-These are found in some bacteria, fungi, and protists.
-Conidia are sexual, non-motile spores of the fungus.
-They also are called mitospores as they're generated through the method of mitosis.
-Oidia are thin-walled asexual spores produced in some filamentous fungi by the process of fragmentation.
So, the correct answer is,’Chlamydospores’.

Note: -Chlamydospores are asexual spores of fungi produced at terminal ends or intercalary places.
-Chlamydospores are commonest in members of the Mucorales,
-Chlamydospores are rich in lipids and well adapted to take care of viability through periods of dormancy
