Mycorrhizae

Question 1

Ectomycorrhizae - definition

Answer 1

Fungal hyphae do not penetrate into cortical cells of plant roots.

Question 2

Endomycorrhizae

Definition

Answer 2

Hyphae penetrate into cortical cells of plant roots.

Question 3

Hartig net

Answer 3

Ectomycorrhizae forms a hyphae mantle and hartig net.

Hartig net is a complex network of fungal hyphae that is site of nutrient exchange between fungus and host plant.

Question 4

Vesicles and arbuscles.

Answer 4

Endomycorrhizae have fungal hyphae which penetrate into cortical cells of plants and form vesicles and arbuscles

Question 5

Ectomycorrhizae - details

Answer 5

Symbiotic relationship between plants and fungi.
Hyphae of fungus forms a sheath around outside of plant root.
Hyphae grow between the plant cells to exchange nutrients (Hartig Net)
Roots thicken and Branch.
Often send up fruiting body.

Question 6

Endomycorrhizae

Details

Answer 6

Symbiotic relationship between fungi and plants.
Hyphae of fungus penetrate plant root cells to exchange nutrients.
Branched hyphae (arbuscles) and vesicles are formed.

Question 7

Advantages of mycorrhizae

Answer 7

Supports faster plant establishment.
Increases access to water and nutrients beyond root zone and delivers them to plants vascular network.
Improves water utilization; greater tolerance to stress and drought.
Increases absorption and root biomass.
Improves utilization of NKP and micronutrients.
Improves soil structure and reduces run off.

Question 8

Ectomycorrhizae associated with what type of plant?

Answer 8

Woody plants

Question 9

Endomycorrhizae association Tim what types of plants?

Answer 9

Herbaceous plants
