Microscopes are used to see the objects at molecular level. Scanning tunneling microscope( STM) is a type of optical microscope that uses optics(light) and lenses to see the enlarged size of the object. This microscope use a small metal tip under a high voltage. when this tip of microscope is brought close to the metal, the metallic tip of microscope draws electrons from the atom (metal) to be observed. This generates an electric current. There is a computer system attached to the microscope that detects the change in the electric current. Computer plots the change in position of atoms in metal.

  2. Basidiomycota
  3. hyphae, mycellium
  4. lichen
  5. mycorrhiza
  6. Ascomycota

Explanation:

1. Zygomycetes reproduce asexually through the haploid spores formed in sporangia, or sexually through diploid nuclei formed in zygospore.

2. Basidiomycota are called club fungi because they produce club-shaped reproductive structures like toadstools.

3. The vegetative body of most fungi is called a hyphae, which consists of an interwoven mass of threadlike filaments called mycelium.

4.  A lichen is a symbiotic association between a fungus and a single-celled alga or cyanobacteria. The fungus protects the photosynthesizer from harsh conditions while consuming the extra nutrients it produces.

5. A mycorrhiza is a symbiotic association between a fungus and the roots of a plant. The fungus receives energy-rich sugar molecules produced by the plant while passing minerals and nutrients from the soil to the root.

6. Ascomycota, also known as sac fungi, include morels, yeasts, and the species that produces penicillin.
