topic 1

Based on this information, which statement accurately compares organelles to organs?

• Functions are carried out more efficiently by organs than by organelles.

• Organs maintain homeostasis while organelles do not.

• Organelles carry out functions similar to those of organs.

• Organelles function in multicellular organisms while organs function in single-celled organisms.

Which organelle is correctly paired with its specific function?

• cell membrane—storage of hereditary information

• chloroplast—transport of materials

• ribosome—synthesis of proteins

• vacuole—production of ATP
