About how much of all kinds of vascular plants exhibit mutualistic association between their roots and certain fungi?
Correct answer: C. 95%
- A. 5%
- B. 100%
- C. 95%
- D. A few
Explanation
The correct answer is 95%. Most vascular plants, about 95%, exhibit a mutualistic association with fungi known as mycorrhizae. This relationship is crucial for the plant's nutrient absorption, particularly for phosphorus. Option A (5%) and Option D (A few) greatly underestimate this relationship, while Option B (100%) overstates it, as not all plant species engage in such associations.
