Which group of eukaryotes LACKS alveoli?
A) apicomplexans
B) ciliates
C) dinoflagellates
D) oomycetes

Accepted Answer

Oomycetes, also known as water molds, belong to a group of eukaryotes called stramenopiles. They do not have alveoli, which are membrane-bound sacs found in the cytoplasm of many other groups of eukaryotes such as apicomplexans, ciliates, and dinoflagellates.
