Question

question 9

all cells have ___, a cell structure capable of making proteins.

• chloroplasts
• mitochondria
• ribosomes
• a nucleus

question 10

prokaryotes and eukaryotes have all of the following in common except ___.

• cytoplasm
• dna
• chloroplasts
• plasma membrane

Explanation:

Analyze Question 9

The question asks for a structure found in all cells that is capable of making proteins. Ribosomes are the universal cellular structures responsible for protein synthesis (translation) and are present in both prokaryotic and eukaryotic cells. Chloroplasts, mitochondria, and nuclei are membrane-bound organelles absent in prokaryotes.

Analyze Question 10

The question asks for a feature that prokaryotes and eukaryotes do NOT have in common. Both cell types share cytoplasm, DNA, and a plasma membrane (along with ribosomes). Chloroplasts are specialized membrane-bound organelles found only in photosynthetic eukaryotes (like plants and algae) and are absent in prokaryotes.
