Answer:
Alternative 4 - Protists are all unicellular
Explanation:
Eukaryotic organisms like protozoa have cells capable of performing various functions such as respiration, excretion, reproduction and locomotion. These cells have structures capable of performing specific roles, as in a prokaryote cell.
However, some types of algae do not have specialized organs and structures such as leaves, stem or flowers. In addition, they have asexual reproduction (through spores). Due to these characteristics, they are considered eukaryotic organisms.
