A) Extracellular digestion is seen in sponges.
B) Extracellular digestion occurs in most animals.
C) Extracellular digestion must involve choanocytes.
D) Extracellular digestion may take place in a tube contained inside the body.

Accepted Answer

Extracellular digestion occurs when enzymes are secreted outside the cell and break down food into smaller molecules that can be absorbed by the cell. This type of digestion is seen in many animals, including sponges, jellyfish, and some worms. In some animals, extracellular digestion may take place in a tube contained inside the body, such as the digestive tract of humans.
