Questions: Algae and protozoa are classified in which kingdom? Protista Eukarya Protozoa Bacteria

The answer is the first one: Protista.

Explanation for each option:

1. Protista: This is the correct answer. Algae and protozoa are both classified under the kingdom Protista. This kingdom includes a diverse group of eukaryotic organisms that are mostly unicellular, although some are multicellular or form colonies.

2. Eukarya: This is incorrect. Eukarya is not a kingdom; it is a domain. The domain Eukarya includes all organisms with eukaryotic cells, which have a nucleus and other membrane-bound organelles. The kingdom Protista is part of this domain.

3. Protozoa: This is incorrect. Protozoa is not a kingdom; it is a subcategory within the kingdom Protista. Protozoa are a diverse group of unicellular eukaryotic organisms, many of which are motile.

4. Bacteria: This is incorrect. Bacteria are classified under the domain Bacteria, which is separate from the domain Eukarya. Bacteria are prokaryotic organisms, meaning they do not have a nucleus or other membrane-bound organelles, unlike algae and protozoa.

In summary, algae and protozoa are classified in the kingdom Protista.
