Question

In ectomycorrhizae, the fungal hyphae form a sheath called a mantle around roots and a Hartig net that extends:
Options
A Into the root cells penetrating cell membranes
B Between root cells without penetrating them
Correct Answer
C Only on the exterior surface of the root
D Into the soil away from the root entirely
Correct Answer

Option B is the correct answer.

Detailed Explanation

In ectomycorrhizae, the fungal partner envelops the roots in a sheath (mantle) and forms a Hartig net of hyphae that extends into the roots between cells. The hyphae do not penetrate the root cells themselves.

Hint

The prefix 'ecto-' means outside, indicating the hyphae remain external to the plant cells.
