Question
Which type of mycorrhiza is characterized by fungal hyphae that penetrate the cell walls of plant root cells but not the cell membranes?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Arbuscular mycorrhizae (also called endomycorrhizae) involve Glomeromycete fungi that form arbuscules which penetrate the cell walls of plant root cells but not the cell membranes. The arbuscules are the site of metabolic exchanges between fungus and host plant.
Hint
The prefix 'arbuscul-' means little tree, referring to the branched structures inside root cells.
