1) As algas são seres eucariontes, ______________, fotossintetizantes, dotados de ___________, e podem ser _____________ ou mult
kirill115 [55]

Answer:

As algas são organismos que anteriormente eram incluídos no Reino Plantae, porém atualmente pertencem ao Reino Protista, sendo a Ficologia (fico = algas; logia = estudo) o ramo da biologia que estuda esses seres: unicelular ou multicelular (filamentosas), eucariontes, fotossintetizantes e viventes em ambientes de água doce (rios, lagos ou superfícies úmidas) ou salgada (mares e oceanos).

Esses organismos autotróficos, dispostos na superfície oceânica (compondo o fitoplâncton), consomem o gás oxigênio dissolvido na água para a sua respiração e liberam através do processo fotossintético cerca de 70 a 90% do oxigênio contido na atmosfera. Recebendo, portanto, a denominação de pulmão do mundo, diferente do que muitos pensam que seja a Floresta Amazônica.

A reprodução assexuada pode ser tanto por divisão binária, isso nas unicelulares, onde a célula se divide ao meio; quanto por fragmentação, mecanismo de cisão de um segmento no talo nas algas multicelulares. Contudo, algumas espécies multicelulares reproduzem por zoosporia, utilizando-se de células flageladas que se desprendem do talo, locomovendo-se até um local favorável para o desenvolvimento.
