Scientists have recently discovered two multicellular organisms with different components in their cell walls. the cell walls have two different polysaccharides, cellulose and chitin. in which two kingdoms would these two multicellular organisms be grouped?

Fungi's are multicellular organisms and contain chitian in there cell walls and plants which belong to the plantae kingdom are also multicellular but they have cellulose in the cell walls.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
