E)numerous small membrane-bound sacs beneath the plasma membrane

Question

Quizplus · Accepted Answer

The feature common to all alveolates is the presence of numerous small membrane-bound sacs beneath the plasma membrane, called alveoli. These structures provide rigidity to the cell and play a role in various cellular processes, including ion transport and protein targeting. While some alveolates, such as dinoflagellates, are capable of bioluminescence, not all possess this trait. The life cycle of alveolates varies widely among different groups, and not all have the complex two-host life cycle seen in some parasitic forms. Some alveolates are autotrophic, meaning they can produce their own food, and not all use lung-like sacs for respiration. Therefore, E is the correct answer.
