a newly discovered organism is made of cells that contain (have) mitochondria, chloroplasts, and dna that is
surrounded by a membrane. what type of cells is this organism made of?
a. bacteria
b. eukaryotic
c. prokaryotic
d. nokaryotic

Explanation:

1. Recall the characteristics of prokaryotic and eukaryotic cells: Prokaryotic cells have no membrane - bound organelles (only ribosomes) and free - floating DNA. Eukaryotic cells have membrane - bound organelles (like mitochondria, chloroplasts in plant cells) and DNA in a nucleus (surrounded by a nuclear membrane).
2. The newly discovered organism's cells have mitochondria, chloroplasts, and DNA surrounded by a membrane. Mitochondria and chloroplasts are membrane - bound organelles, and DNA in a membrane - bound nucleus is a feature of eukaryotic cells. Prokaryotic cells do not have these membrane - bound organelles (except ribosomes) and have free - floating DNA. Bacteria are prokaryotic, and “Nokaryotic” is not a valid cell type. So the cells must be eukaryotic.

Answer:

B. Eukaryotic
