Answer:
Cell organelles are small structures that exist within cells and perform specialized functions
Based upon the presence and absence of membrane cell organelles can be classified into three types:
- Membrane less: Cell organelle that lack membrane for example ribosomes they are not bounded by any membrane.
- Single membraned: Cell organelle that are bounded by single membrane but they are only found in Eukaryotic cell. For example lysosome, Endoplasmic reticulum, lysosome, vacuole.
- Double membraned: Cell organelle that are bounded by double membrane. Example chloroplast and mitochondria, they are only present in eukaryotic cell.

Binary fission is the method by which prokaryotes produce new individuals that are genetically identical to the parent organism.
The four main macromolecules are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates typically are used for energy production within the body, lipids are used for energy storage, proteins are typically used for structural support in things like your hair or nails, and nucleic acids are used for storing genetic material.
