Based on your descriptions, here are the corresponding organelles:
-
Lysosomes: These are organelles that digest macromolecules, breaking down waste materials and cellular debris.
-
Ribosomes: This organelle synthesizes proteins and can be found free-floating in the cytoplasm or attached to the rough endoplasmic reticulum.
-
Mitochondria: Often referred to as "cellular power plants," mitochondria convert organic materials into energy in the form of ATP through cellular respiration.
-
Endoplasmic Reticulum: This membrane-bound organelle serves as the production and processing center of proteins and some lipids. The rough ER is studded with ribosomes, while the smooth ER is involved in lipid synthesis and detoxification.
-
Organelle: This term generally refers to any functional structure within a cell, often described as a "small organ" and usually possessing a membrane-bound structure.
