Detailed explanation-1: -An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
Detailed explanation-2: -As we saw above, every organ is made up of two or more tissues, groups of similar cells that work together to perform a specific task. Humans-and other large multicellular animals-are made up of four basic tissue types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
Detailed explanation-3: -Which is the major difference between an organ and an organelle? An organ is a collection of tissues performing specific functions in the human body. On the contrary, organelles are cellular structures performing specific functions within the cell.
Detailed explanation-4: -Macromolecules such as carbohydrates, lipids, proteins, and nucleic acids (DNA, RNA) make up all cellular organelles.
