Straight chain, branched chain, and ring
Answer: A compound is a substance in which two or more elements are combined together chemically.
Explanation: Elements present in a compound are always in a fixed proportion and can be separated only by a chemical method. For example, water is a compound composed of hydrogen and oxygen atoms in the ratio of 2:1. The chemical formula of water is H2O.
Answer:
- sporangia , zygospore
- Basidiomycota
- hyphae, mycellium
- lichen
- mycorrhiza
- 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.
