Question

3 notice that the large gastrovascular cavity of your specimen is partitioned by primary septa, inward extensions of the body wall. openings in these septa, called ostia, allow water to circulate throughout the body. smaller, secondary septa (or incomplete septa) further subdivide the main chambers. what do you suppose is the function or purpose of these folds of the gastrovascular cavity wall (the septa)? 4 count the number of primary septa on your specimen and record that value in the space provided. compare your finding with other lab groups. do all of the sea anemone specimens in your lab have the same number of primary septa?

Explanation:

The septa in the gastrovascular cavity likely increase the surface - area for digestion and gas exchange. Counting primary septa helps in understanding the anatomical consistency among specimens.

Answer:

The function of the septa is likely to increase surface - area for digestion and gas exchange. For the number of primary septa, it needs to be counted in the actual specimen and compared with other lab groups to determine if sea anemone specimens have the same number.
