Which of the following combinations of characters is true for slime moulds?
Options
- AParasitic, plasmodium with true walls, spores dispersed by air currents
- BSaprophytic, plasmodium without walls, spores dispersed by water
- CParasitic, plasmodium without walls, spores dispersed by water
- DSaprophytic, plasmodium without walls, spores dispersed by air currents
Correct answer
D. Saprophytic, plasmodium without walls, spores dispersed by air currents
Step-by-step solution
The members of fungal class-Myxomycetes are commonly called true slime moulds. These are saprophytic and their vegetative phase is represented by a free living irregularly shaped mass of protoplasm without walls and having several diploid nuclei embedded in it. It is called plasmodium. During reproduction, slime moulds produce haploid spores, which are dispersed by air currents, rain and mites.
