Some green algae show alternation of generations. All land plants show alternation of generations. No charophyceans show alternation of generations. Keeping in mind the recent evidence from genetic studies, the correct interpretation of observations is that: A) charophyceans are not related to either green algae or land plants. B) plants evolved alternation of generations independently of green algae C) alternations of generations cannot be beneficial to charophyceans D) land plants evolved directly from the green algae that perform alternation of generations E) scientists have no evidence to indicate whether or not land plants evolved from any kind of alga
