Although radiographic examination provides essential information for acetabular classification, CT, including multiplanar reconstruction, is helpful in the visualization of complex fractures ( 7 ).
This allowed scientists from years to change the classification of blue-green microorganism from bacteria to algae. In the 1830s, algae were classified into major groups based on color (e.g., red, brown, and green). The colors are a reflection of different chloroplast pigments, such as chlorophylls, carotenoids, and phycobiliproteins.
