Match each cell organelle with its description

Attached diagram shows how they match up;

Explanation:

Centrioles-  cylindrical tubular organelles that are involved in cell division

Endoplasmic reticulum-tube-like structures that are the site of protein and lipid synthesis

Chloroplasts- contain chlorophyll and are the site of photosynthesis

Lysosome  - digestion organelles that break down biomolecules into smaller molecules

Mitochondria  - the site of cellular respiration and energy production

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
