Spongy tissue is a type of tissue found both in plants and animals.. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf.The spongy mesophyll's function is to allow for the interchange of gases (CO 2) that are needed for photosynthesis.
By cooperatively moving their flagella, choanocytes filter particles out of the water and into the spongocoel, and out through the osculum.This improves both respiratory and digestive functions for the sponge, pulling in oxygen and nutrients and allowing a rapid expulsion of carbon dioxide and other waste products.
