Question

25. Organelles that contain DNA include a. ribosomes b. mitochondria c. chloroplasts d. b&c; are correct e. a,b&c; are correct. 26. Which of the following pairs is mismatched? a. nucleolus, ribosomal RNA. b. nucleus, DNA replication c. lysosome, protein synthesis d. cell membrane, lipid bilayer. 27. Which of the following relationships between cell structures and their respective functions is NOT correct? a. b. c. d. e. cell wall: support and protection. chloroplasts: chief site for cellular respiration chromosomes: genetic information. ribosomes: site for protein synthesis mitochondria: formation of ATP

Explanation / Answer

25. B&C are correct. Plastids namely mitochondria and chloroplast contains DNA as their genetic material. Ribosome is made up of ribosomal RNA and ribosomal protein.

26. Option C . Lysosome is not the site for protein synthesis, ribosome is the site for protein synthesis.

27. Option B. Chloroplast is the site for photosynthesis. Mitochondria is the site for cellular respiration and ATP production.
