How does the digestive process in cnidarians differ from sponges?

Explanation:

digestive process in cnidarians differ from sponges

1. i) sponges have intracellular digestive system.

 ii). They feed on planktons by filtering water.  

 iii). Digestion takes place completely in choanocyte cells.

Cnidarians

1. i) Cnidarians are predators and feed on small fish, krill and many small species.

ii )All cnidarians are carnivores and have very simple body structures adapted as predators.

 iii) Cnidarians carry out extracellular digestion. Enzymes break out the food into small particles. Cnidarians have an incomplete digestive system and have only one opening.

ysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. lysosomal enzymes are synthesized in the endoplasmic reticulum (er), are transported to the golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label.
