I think its collar cells
organelles
Because no other animal has anything like collar cells..
Sponges get food from the water around them.
Sponges have a single body cavity known as the spongocoel . The spongocoel is critical to the food gathering strategy of sponges.
sponges
Collar cells are found in sponges. Their function is to beat the flagella back and forth in order to make water go through the sponge. Apart from the sponge picking food particles from the water, the collar cells also do the same.

no. they have tissue like stuff but not true tissue.
Sponges are made of several cell types that each have certain functions. The ameobacyte (or ameoba-type cell) digests food that is driven to it by the collar cells, which each possess a flagellum
Sponges have a cavity lined with specialized cells that absorb the food that enters or is swept in by cilia. Not very complex.
specialized organelles called lysosomes digest food in the cell...
choanocytes are resonsible for current flow and trapping food particles in sponges source: my invertebrate zoology textbook :)
Sponges process their food by fillter feed and fillter fecies...
Sponges filter their food when water flows by.
Sponges get food from the water around them.
No, sea sponges can not make their own food. They obtain their nutrition from the food particles in the water. Sponges primarily eat bacteria, phytoplankton, and other small food bits out of the water.
plant-like: contain chlorophyll and make their own food using photosynthesis, have cell walls, and no specialized ways to move from place to place. animal-like: cannot make their own food; they capture other organisms for food, do not have cell walls, and have specialized ways to move from place to place. fungus-like: cannot make their own food; they absorb food from their surroundings, some organisms have cell walls; others do not, and have specialized ways to move from place to place.
