In cell b2 same cost may or may not appear based on the value in cell a2 (if value changes in a2, then this cost is multiplied with the difference of value in cell (a2-a1), otherwise value of previous cell appears in cell b2.
Each mature Volvox colony is composed of numerous flagellate cells similar to Chlamydomonas, up to 50,000 in total, and embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of a gelatinous glycoprotein.olvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae.
Protists are one-celled organisms. Symbiotic protists are protists that live with other larger organisms in a mutually beneficial relationship. The anaerobic parabasalid species of protist is an example. Photosynthetic protists are the protists that process sunlight. The dinoflagellates Noctiluca and Pyrocystis are examples of this type of protist. There are also protists that serve both purposes: they are both symbiotic and photosynthetic. The protists zooxanthellae are an example of this type of protist.
