Question

which statement applies to eukaryotic cells but not to prokaryotic cells?
a utilize mitochondria during energy production
b flow of nutrients and wastes occurs across a membrane
c contain dna as genetic material
d perform metabolic processes with the help of chemicals

Explanation:

• Option A: Eukaryotic cells have mitochondria (the powerhouse of the cell) for energy production (through processes like aerobic respiration). Prokaryotic cells lack membrane - bound organelles like mitochondria. They produce energy through other means (e.g., on the cell membrane in some cases).
• Option B: Both prokaryotic and eukaryotic cells have a cell membrane. Nutrients enter and wastes exit across this membrane in both types of cells.
• Option C: Both prokaryotic and eukaryotic cells have DNA as their genetic material. In prokaryotes, it is usually in a circular, non - membrane - bound form (nucleoid), while in eukaryotes, it is linear and enclosed in a nucleus.
• Option D: Both prokaryotic and eukaryotic cells perform metabolic processes. Metabolic processes (such as breaking down food molecules) require the help of chemicals (e.g., enzymes) in both cell types.

Answer:

A. Utilize mitochondria during energy production
