George's science class looked at living cells under a microscope. The students studied an organism that had many different kinds of cells, but each cell had a cell wall and nucleus. To which kingdom did this organism belong?

A. Animals
B. Protists
C. Monerans
D. Plants **?

D.Plants as @PsyDAG said :)

JUST ANSWER THE QUESTION NEXT TIME

To determine the kingdom to which the organism belongs, we need to analyze the characteristics of the cells observed. In this case, we see that each cell of the organism has a cell wall and a nucleus.

Animals typically do not have a cell wall, so the organism does not belong to Kingdom Animalia (option A).

Protists are one of the most diverse kingdoms, and while some protists may have a cell wall, they do not universally possess a nucleus. Therefore, we can eliminate Kingdom Protista (option B).

Monerans, also known as bacteria, do have a cell wall, but they lack a nucleus. Since the organism in question has both a cell wall and a nucleus, we can rule out Kingdom Monera (option C).

Finally, we are left with Kingdom Plantae (option D). Plants are known to have cells with a cell wall and a nucleus. Therefore, the organism described in the question most likely belongs to Kingdom Plantae.

So, the correct answer is D. Plants.

A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. They are found in bacteria, archaea, fungi, plants, and algae.
