Water plants - Suiso

Japanese: 水草 - すいそう

Also known as aquatic plants. A general term for plants that grow in water. Includes all emergent plants (those that grow near the shore with the lower part of their stems or roots submerged in water, such as reeds and cattails), floating-leaf plants (those that grow at a depth of 1-2m and have leaves that float on the surface, such as water chestnut and horse chestnut), submerged plants (those that are submerged in water at a depth of 2-10m, such as hydrilla and eelgrass), floating plants such as duckweed, algae, and phytoplankton. In general, nutrients and other substances dissolved in the water are absorbed through the surface of the body. In addition, many of them have poorly developed roots and well-developed aerial tissue. Due to their various physiological and ecological characteristics, aquatic plants are considered to be plants that have returned from terrestrial life to aquatic life.

Japanese:

〈みずくさ〉，水生植物とも。水中に生育する植物の総称。抽水(ちゅうすい)植物（ヨシ，ガマなど，茎の下部や根を水につけ岸近くで生育するもの），浮葉植物（ヒシ，トチカガミなど，水深１〜2mに生え葉を水面に浮かべるもの），沈水植物（クロモ，エビモなど，２〜10m付近で体全体を水につけているもの），ウキクサなどの浮水植物，藻類，植物プランクトンなどをすべて含む。一般に栄養塩類などは水中に溶存するものを体表面から吸収する。また根の発達は悪く，通気組織はよく発達しているものが多い。さまざまな生理・生態的特徴から，水草は陸上生活から水中生活にまい戻った植物と考えられる。
