A Correct answer
Explanation

C. merolae is a club-shaped, unicellular red alga that lives in highly acidic environments and in warm conditions. C. merolae has a single chloroplast and a single mitochondrion, but lacks a vacuole and a cell wall. The organism's genome was the first full algal genome to be sequenced in 2004; its plastid was sequenced in 2000 and 2003, and its mitochondrion in 1998.
