Q. Consider the following statements regarding Kingdom Fungi:
1.Fungi are multicellular organisms with cell walls composed of chitin and lack chloroplasts.
2.Mycorrhizal fungi form symbiotic associations with plant roots, significantly improving nutrient uptake and water relations.
3.All fungi, including mushrooms, possess flagella or cilia for active locomotion throughout their life cycle.
Which of the statements given above is/are correct?
Answer: D
Notes:
Explanation:
Statement 1&2 is correct. Fungi are eukaryotic, mostly multicellular organisms (like molds) or single-celled (yeasts) with cell walls composed of chitin and lack chloroplasts, making them heterotrophic rather than photosynthetic. Mycorrhizal fungi form vital symbiotic relationships with plant roots, expanding root surface area to increase uptake of water and nutrients like phosphorus.
Statement 3 is incorrect. Fungi generally lack mechanisms for locomotion. They grow toward food sources rather than swimming or walking toward them.
