Study Notes
- Topics covered include cell structure, specialized cells, and levels of organization.
Cell Structure
- Components include the cell membrane, cytoplasm, nucleus, R.E.R (rough endoplasmic reticulum), ribosomes, mitochondria, Golgi apparatus, chloroplasts, cell wall, and large vacuole.
- The cell membrane, which is partially permeable, is a thin layer surrounding the cytoplasm and controls what enters and exits the cell.
- Cytoplasm is a jelly-like material filling the cell.
- The nucleus contains DNA in the form of chromosomes.
- R.E.R produces and transforms proteins.
- Ribosomes are very small structures using DNA information to make protein molecules.
