Which of the following organisms are the smallest chlorophyll-containing plants?

Explanation:
Algae are the smallest organisms that contain chlorophyll and perform photosynthesis. Many algae are microscopic, including single-celled forms, so they represent the tiniest chlorophyll-containing photosynthetic organisms often labeled as plants. Bacteria may have photosynthetic pigments in some types but don’t use chlorophyll in the way plants do, and they aren’t classified as plants. Fungi do not photosynthesize, and protozoa are non-photosynthetic. So the smallest chlorophyll-containing plants among the options are algae.
