Question

question 21 eukaryotic cells a. are all photosynthetic b. are more closely related to bacteria than archaea c. have plasmids d. have mitochondria

Explanation:

Eukaryotic cells have membrane - bound organelles, and mitochondria are one of them. Not all eukaryotic cells are photosynthetic (e.g., animal cells). Eukaryotes are more closely related to archaea than bacteria in evolutionary terms. Plasmids are mainly found in prokaryotes, not typically in eukaryotes.

Answer:

D. have mitochondria
