Carotenoids are organic pigments that are found in the chloroplasts and chromoplasts of plants and some other photosynthetic organisms, including some bacteria and some fungi. Carotenoids can be produced from fats and other basic organic metabolic building blocks by all these organisms.or the same reason, carotenoid colors often predominate in ripe fruit after being unmasked by the disappearance of chlorophyll. Carotenoids give the characteristic color to carrots, corn, canaries, and daffodils, as well as egg yolks, rutabagas, buttercups, and bananas.
The defining component of Linux is the Linux kernel, an operating system kernel first released on 5 October 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy.
7 Comments. 1  Take from http://en.wikipedia.org/wiki/Open-source_software. Open source software (OSS) began as a marketing campaign for free software. 2  That is because the Linux Kernel is free and open source. That is why there are so many different distributions. The Kernel: http://www.kernel.org/. Unlike windows or os x, linuxâs actual source codes are open for modications to everybody. as for Windows and OSx, their source codes are compiled and cannot be decompiled, reverse engineer and/or modify.
