Questions Related to classification of fungi
Which of the following statements is not correct regarding mycorrhiza ?
-
It helps In absorption of phosphorus from the soil.
-
It is a symbiotic association of fungi with the roots of higher plants.
-
It helps the plant in developing resistance to root-borne pathogens.
-
None of these
Mycorrhiza is the
-
Symbiotic association between fungus and roots of seed plants.
-
Parasitic association between fungus and the roots of seed plants.
-
Saprophytic association between fungus and roots of seed plants.
-
All of the above.
Mycorrhiza refers to the symbiotic association of a fungus and roots of vascular plants. During this association, the fungus colonizes on the roots of the host seed plants either intracellularly or extracellulary and is generally mutualistic rather than pathogenic.
Mycorrhiza is a symbiotic association between root and
-
Alga
-
Fungus
-
Bacteria
-
Virus
A mycotrophic humus plant is
-
Neottia
-
Wullschleigelia
-
Monotropa
-
None of the above
Neottia is a mycotrophic humus plant because it feeds on fungi for obtaining food and energy. This is because these plants lack chlorophyll to make their own food material.
Mycorrhiza, a relationship between fungi and roots of higher plants is
-
Parasitic relationship
-
Saprophytic relationship
-
Symbiotic relationship
-
Epiphytic relationship
Mycorrhiza is a symbiotic association between Fungi and roots of higher plants, which grow in mineral deficient soil. It helps to absorb water and minerals like phosphorous from soil for the benefit of plant and in turn gets nutrition from the plant, as fungi cannot synthesize its own food.
A symbiotic association between fungus and underground part of a plant is
-
Hyperparasite
-
Mycorrhiza
-
Endophyte
-
Subterranean parasite
A. Hyperparasite is an organism which lives off another parasite.
Mycorrhiza does not help the host plant in:
-
enhancing its phosphorus uptake capacity
-
increasing its tolerance to drought
-
enhancing its resistance to root pathogens
-
increasing its resistance to Insects.
Which one of the following plays an important role in phosphate nutrition of plants?
-
VAM
-
1PM
-
Legumes
-
Cyanobacteria
Role of VAM in Nutrient uptake of crop plants:
- Microorganism and their role in soil must be considered as a key component among those conferring soil fertility and productivity.
- One of the most important plants-microbe interactions is the association of vesicular-arbuscular mycorrhizae (VAM) fungi with higher plants.
VAM represents
-
Saprophytic fungi
-
Symbiotic fungi
-
Saprophytic bacteria
-
Symbiotic bacteria
VAM is
-
Bioinsecticide
-
Bioherbicide
-
Endomycorrhiza
-
Ectomycorrhiza
