Study Notes
Cellular Composition
- All cells share fundamental components: plasma membrane, ribosomes, cytoplasm, and DNA.
- The plasma membrane encloses and protects the cell.
- Ribosomes are composed of RNA and proteins.
- Cytoplasm is a gel-like substance filling the cell.
- DNA carries the genetic blueprint of the cell.
Macromolecules
- Cellular structures arise from the assembly of macromolecules, including nucleic acids, proteins, lipids, and polysaccharides.
Cellular Functions
- Cellular components are essential for:
- Providing structural support
- Nutrient uptake from the environment
- Energy conversion
- Replication through genetic material
Main Cell Parts
- The cell is comprised of three major parts:
- Cell membrane: The outer boundary
- Nucleus: Contains nucleolus, DNA, and RNA
- Cytoplasm: The internal fluid environment
