Study Notes
Atomic Structure
- The basic units of life are composed of CHNOPS: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulfur.
Molecular Structure
- A molecule is a group of atoms bonded together, examples include H2O and proteins.
Cellular Structure
- An organelle is a structure within a cell that has a specific job, similar to organs in the human body, examples include the nucleus and mitochondria.
- A cell is the smallest unit of life that can live on its own, and it makes up all living organisms.
Tissue Structure
- A tissue is a group of cells that function together, examples include skin and nervous tissue.
Organ Structure
- An organ is a collection of tissues that work together, examples include the heart and lungs.
Organ System Structure
- An organ system is a group of organs that work together to perform a specific function, examples include the respiratory, digestive, and reproductive systems.
Cellular Classification
- Cells can be classified as Prokaryotic (without a nucleus) or Eukaryotic (with a nucleus).
- Organisms are individual life forms made up of cells.
