Answer» Correct Answer - C Diatoms are major group of unicellular eukaryotes. They have a unique silica cell wall comprising of two separate valves (shells). Diatoms produce auxospores, which are involved in re-etablishing the normal size. This occurs each daughter cell produced by cell division inherits one of the two valves that makes up the frustule (a silica cell wall ) and then grows a smaller valve within it. |
