Study Notes
Basic Unit of Life
- The cell is recognized as the fundamental unit of life, serving as the building block for all living organisms.
Function of Ribosomes
- Ribosomes are crucial in protein synthesis, translating messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins.
Passive Transport
- The process of diffusion allows substances to move across cell membranes without the expenditure of energy. This includes types like simple diffusion and facilitated diffusion.
Water Molecule Bonds
- Water molecules are held together by polar covalent bonds, resulting in unique properties such as cohesion and high surface tension.
Phenotype in Genetics
- In genetics, 'phenotype' refers to the observable characteristics or traits of an organism, which are influenced by both genetic makeup (genotype) and environmental factors.
