Chlorophyll c - Wikipedia The different forms of chlorophyll absorb slightly different wavelengths for more efficient photosynthesis. This is in contrast to the occurrence of three low temperature emission bands in green, blue-green and red algae, and in chloroplasts of higher plants. A fish kill, also known as a fish die-off is when a large concentration of fish die. Like chlorophylls B, C, D, E and F, these molecules improve light energy absorption, but they are not a primary part of photosynthesis. This can reduce oxygen concentrations to below sustainable levels. [56] Alginic acid is used as a stable component of a battery anode. Blades are also often the parts of the alga that bear the reproductive structures. Brown algae's photosynthetic system is made up of a P700 complex of chlorophyll a, chlorophyll c, and carotenoids (most notably fucoxanthin). Once a major source of iodine and potash, brown algae are still an important source of algin, a colloidal gel used as a stabilizer in the baking and ice-cream industries. This has lead to their classification under the Kingdom Chromista 4. Within the visible light spectrum, chlorophyll strongly absorbs red and blue light while reflecting green light 48. Multicellular green algae is also not considered phytoplankton for the same reasons. However, chlorophyll is not actually a single molecule.

Rapid measurement of brown tide algae using Zernike moments and Chloroblasts of brown algae contain, in addition to chlorophyll, the pigment fucoxanthin, resulting in a brown or olive-green color.

Any one of certain large, tough, brown seaweeds; the source of potassium, iodine, algin, and sodium carbonate. Cyanobacteria and other phytoplankton photosynthesize as plants do, and produce the same sugar and oxygen for use in cellular respiration. This reflects their different metabolic pathways. Without phytoplankton, the oxygen supply of the ocean would be cut in half. Phaeophyta (Brown Algae) - Biology Wise
