QUE SIGNIFIE PORIFERAN EN ANGLAIS
Éponge
Les éponges sont des animaux du phylum de Porifera. Ce sont des organismes multicellulaires qui ont des corps pleins de pores et de canaux permettant à l'eau de circuler à travers eux, constitués de mésynyle analgésique en forme de gelée entre deux couches minces de cellules. Les éponges ont des cellules non spécialisées qui peuvent se transformer en d'autres types et qui migrent souvent entre les couches cellulaires principales et le mesohyle dans le processus. Les éponges n'ont pas de système nerveux, digestif ou circulatoire. Au lieu de cela, la plupart reposent sur le maintien d'un flux d'eau constant dans leur corps pour obtenir de la nourriture et de l'oxygène et pour éliminer les déchets.
