An association in which fungal hyphae penetrate the outer cells of the plant root forming coils swellings and minute branches and also extend out into surrounding soil is called______________?
Correct answer: B. Endomycorrhizae
- A. Mycorrizael association
- B. Endomycorrhizae
- C. Ectomycorrhizae
- D. Lichen
Explanation
Endomycorrhizae grow into the outer root cells and form coils, swellings, or arbuscule-like branches while their hyphae also extend into the surrounding soil. Ectomycorrhizae mainly form a sheath around roots and grow between cells rather than penetrating the cells, so that is the likely mistaken choice.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
