Question

Sponges display nonspecific immunity. In an experiment, the cells of two different sponges were mixed and placed within a petri dish. The cells from each sponge sorted and arranged themselves together according to organism. What does this characteristic demonstrate? Sponges have memory T-cells and share a more recent common ancestor with vertebrates than other invertebrates o The experiment provides evidence for the speed of evolution and the use of specific immunity within the organism. O Sponges have an ability to recognize their own cells as a characteristic of acquired immunity O Sharing genetic information from cell to celil is possible by means of receptors and protein-ined pits

Explanation / Answer

Answer

Sharing genetic information from cell to cell is possible by means of receptors and protein lined pits

Sponges have species specific ability of aggregation to develop sponges. They are able to distinguish self from non self. They have membrane receptors for cellular recognition. Most receptor molecules are glycoproteins that help them to recognise their own species.
