31. The bluegreen algae occur as symbionts in about 8 % of the known lichens. 32. Insect-associated symbionts have been found to share a similar set of features. 33. Microorganisms also have an important place in most higher-order multicellular organisms as symbionts . 34. Freshwater gemmules may also include phytosynthesizing symbionts . 35. Paleozoic corals often contained numerous endobiotic symbionts . 36. Without their symbionts , coral growth would be too slow to form significant reef structures. 37. Antibiotic active against the Wolbachia symbionts of the worm have been experimented with as treatment. 38. It can regain symbionts , possibly of a different species, at a later time. 39. The identification of the associated fungal symbionts is impossible without the use of molecular methods. 40. Most symbionts of deep-sea animals.
