While collecting pond samples, Laura found an organism she had never seen before. She brought the organism to class and studied its characteristics. Laura's observations are listed below:
1. The organism is unicellular.
II. The cell has a nucleus.
III. The cell contains chloroplasts.
IV. The cell contains mitochondria.
V. The cell has a cell wall.
Based on Laura's research, to which biological kingdom does the organism belong?
OA. Protista
OB. Fungi
OC. Plantae
OD. Bacteria

The correct answer is - option A.

Explanation:

Protists are single-celled eukaryotic organisms and usually move by cilia, flagella. Generally, they lack cell walls however, some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be. They also contain the mitochondria for energy purposes.

Thus, laura should place the organism she found in the Protista biological kingdom according to their characteristics.
