OverviewAI-generated
Phaeophyceae is a class of organisms within the phylum Ochrophyta and kingdom Chromista. The taxon, described by Kjellman in 1891, is commonly known as brown algae. Its nomenclature follows the International Code of Nomenclature for algae, fungi, and plants. The group has existed for about 150 million years.
These organisms inhabit marine, brackish, and freshwater environments. The taxon status is accepted. Records of Phaeophyceae are held by institutions such as SDNHM, UCMP, and US, primarily in the United States.

褐藻（學名：Phaeophyceae）是屬較高等的多細胞藻類，屬真核細胞生物，有1,500種左右，主要分布於大陸附近的水域，則淡水種罕見。褐藻纲外表從暗褐色的橄欖綠都有，其取決於褐藻素與葉綠素的比例。至於它們的大小各異，從只有數公分的水雲屬到1∼100公尺的巨藻屬。褐藻門則同時可以無性生殖和有性生殖繁殖。

褐藻（かっそう、英語: brown algae）はワカメやコンブ、ヒジキ、モズクなどを含む藻類の一群、またはこれに属する藻類のことである。分類学的には、オクロ植物門（不等毛植物門）の褐藻綱（学名: Phaeophyceae）にまとめられる。 全ての種が原形質連絡をもつ多細胞性の体をもち、比較的複雑な組織・器官分化を示すものや、長さ数十メートルに達するものもいる（右図）。陸上植物などとは独立に多細胞化を遂げたグループであるが、原生生物の中では最も複雑な多細胞体をもつ。細胞壁はセルロースやアルギン酸、フコイダンなどを含む。珪藻など他の不等毛藻と同様、二次共生した紅藻に由来する葉緑体をもつ。藻体はふつう褐色をしており、葉緑体は光合成色素としてクロロフィルa、クロロフィルc、フコキサンチンなどを含む。多くは単相の配偶体と複相の胞子体の間で世代交代を行うが、複相の世代のみをもつものもいる。ほとんどの種は沿岸域に生育する海藻であり、特にやの大型種は藻場を形成し、沿岸域の生態系の重要な構成要素となっている（右図）。上記のように食用として身近な海藻が含まれ、また細胞壁成分であるアルギン酸は食品添加物などに広く利用されている。
