Algae - Nutrient storage Britannica
WebAlgae uses photosynthesis to convert solar energy into chemical energy which is stored in fatty or lipid oils. One challenge of converting algae into biodiesel fuel is that production costs are uncertain and vary because of feedstock availability, prior claims to land, and regulations based on environmental affects of large areas of monoculture. WebAlgal cells are eukaryotic and contain three types of double-membrane-bound organelles: the nucleus, the chloroplast, and the mitochondrion. In most algal cells there is only a single nucleus, although some cells are multinucleate. In addition, some algae are siphonaceous, meaning the many nuclei are not separated by cell walls. The nucleus contains most of … circle leaf border png
