Question
Distinguish between intracellular and extracellular digestion.
Solution
Intracellular digestion | Extracellular digestion | |
1 | The digestion of food occurs within the cell. | The digestion occurs in the cavity of alimentary canal. |
2 | Digestive enzymes are secreted by the surrounding cytoplasm into the food vacuole. | Digestive enzymes are secreted by special cells into the cavity of alimentary canal. |
3 | Digestive products are diffused into the cytoplasm. | Digestive products diffuse across the intestinal wall into various parts of the body. |
4 | It is a less efficient method. | It is a more efficient method of digestion. |
5 | It occurs in unicellular organisms and some other lower organisms. | It occurs in multicellular organisms. |

If body of any animal is cut through ______ axis of body, it may or may not produce two equal halves. Depending upon this property, there are different types of animal bodies. In the case of ______ body, there is no any such imaginary axis of the body through which we can get two equal halves. For example Amoeba, ______ some sponges. In radial symmetry type of body, if imaginary cut passes through central axis but any plane of body, it gives two ______ halves. For example Starfish. In case of this animal, there are five different planes passing through ______ axis of body through which we can get two equal halves. In Bilateral symmetry type of body, there is only one such imaginary axis of body through which we can get two equal halves. For example: ______ fishes, frog, birds, human, etc.
