Study Notes
- Cells are the smallest living units of an organism and all cells share common features like a cell membrane, cytoplasm, and DNA.
- There are two main categories of cells: eukaryotic cells (more advanced with a nucleus and organelles) and prokaryotic cells (simpler, without a nucleus or membrane-enclosed organelles).
- Organelles are specialized cell parts with unique functions, such as the nucleus (containing DNA and nucleolus), ribosomes (synthesize proteins), endoplasmic reticulum (transport materials), Golgi apparatus (modify proteins), vacuoles (store materials), lysosomes (break down cell debris), mitochondria (produce energy), and cytoskeleton (maintains cell shape).
- Plant cells have chloroplasts for photosynthesis and a cell wall for support, while animal cells lack a cell wall.
- Some cells have unique structures like cilia (respiratory tract cells with hair-like projections) and flagella (some bacteria and sperm cells with tail for movement).
