Storage of Organic Carbon Questions

Question 1

Submit Answer 1

Answer 1

Excess organic energy is stored in a variety of complex molecules. Storage products include lipids, glycerol and various polyols. These molecules tend to be stored in vacuoles and moved around the thallus to storage areas. While it is not clear what mechanisms determine how the products are stored, and where these stores are located, the products are commonly present in survival structures such as sclerotia and spores. Older hyphae commonly function as storage areas and the products are moved presumably as a function of the relative activity of different parts of the thallus.

Question 2

Submit Answer 2

Answer 2

The evidence may be categorised into two types: types of defences and interactions. If a sclerotia has significant mechanical and chemical defences which deter potential hyperparasites, then some form of coeveolution may be indicated. Further, if the parasite uses the cytoplasm of the target as a source of energy, the hypothesis is supported. Not all hyperparasitic interactions involve both characters.
