Question
Rocks up to 10,000 years old can be dated with the size–frequency approach to a method that measures the thalli of these organisms. For 10 points each:
[10m] Name these organisms that often act as pioneer species. These organisms are composed of a photobiont interspersed within hyphae filaments.
ANSWER: lichens
[10e] Lichens are symbionts of algae and organisms in this kingdom that use hyphae to consume nutrients from trees. Yeasts and molds are part of this kingdom, which is the subject of mycology.
ANSWER: fungi [or funguses]
[10h] Fungi commonly asexually reproduce via spores such as those formed by the sporangia or these non-motile spores. Most species of ascomycetes (“ass-ko-MY-seets”) reproduce asexually by forming these spores.
ANSWER: conidia [or conidium or conidiospores; accept asexual chlamydospores or chlamydoconidium or chlamydoconidia; accept mitospores; reject “conidiophores”]
