Symbionts which help plants in uptake of phosphorous and trace metals such as zinc and copper.
Correct answer: C. Fungi
- A. Bacteria
- B. Viruses
- C. Fungi
- D. Cyanobacteria
Explanation
Mycorrhizal fungi form symbiotic associations with plant roots and extend fungal hyphae through the soil, increasing the area from which phosphorus and trace metals such as zinc and copper can be absorbed. The plant supplies carbohydrates to the fungus in return. Students may choose bacteria because some bacteria are plant symbionts, but the classic symbionts responsible for this mineral uptake are fungi.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
