These organisms reproduce using gonidia, not spores, a process discovered by children’s author Beatrix Potter when she studied their (0[1])Cladonia genus. The trebouxioid (0[2])(“TREY-boo-shoyd”) type (0[1])of these organisms can survive 98% desiccation (0[2])and is used for simulations of Martian (0[1])terraforming. (0[2])Archaeologists date glacial deposits by measuring the size of these (0[1])organisms’ thalli (20[1])(“THALL-eye”). These organisms indicate sulfur dioxide pollution because their (*) fruticose morphology (0[1])is sensitive (10[1])to acid (0[1])rain. Chlorophyte cells in these organisms are scattered throughout the hyphae (0[1])(“HIGH-fee”). Caribou (0[3])mainly prey (0[1])on these pioneer (10[3]0[1])species. (10[2])Unlike in (10[1])mycorrhizae (10[2]0[1])(“mih-CORE-ih-zay”), fungal cells in these organisms use cyanobacteria or algae to harvest light. (10[1])For 10 points, name these symbiotes that resemble (10[2])mosses. (10[5]0[1])■END■ (10[13]0[2])
