What is the term for the symbiotic association between fungi and plant roots?

Evergreen
Mycorrhizae
Organic Fertilization
Chlorosis

The correct answer is: Mycorrhizae

Mycorrhizae is the correct term for the symbiotic association between fungi and plant roots. This relationship is beneficial for both parties as the fungus helps the plant absorb essential nutrients and water from the soil while receiving sugars and other nutrients from the plant in return. This mutualistic relationship is crucial for the health and growth of many plant species, making option B the correct answer. The other options are not relevant to the symbiotic association between fungi and plant roots. Choice A, Evergreen, is a term used for trees that retain their leaves year-round. Choice C, Organic Fertilization, refers to the use of organic materials to improve soil fertility. Choice D, Chlorosis, is a condition characterized by yellowing of plant leaves due to a lack of chlorophyll.
