    Study Notes

    Introduction to the Cell and Biological Molecules

    • The session covers the differences between prokaryotic and eukaryotic cells and the main organelles in a mammalian cell.
    • Classification is the science of grouping objects according to their similar characteristics, and taxonomy is the more respected classification system for living things.
    • The purpose of classification is to know how many known species there are, their characteristics, and the relationships between them.
    • The classification system consists of seven levels: Kingdom, Phylum, Class, Order, Family, Genus, and Species.
    • The five kingdoms of organisms are Animalia, Plantae, Fungi, Protista, and Monera.
    • Free-living cells and the cells of multicellular organisms are subdivided into two major classes: Eukaryotes (true nucleus) and prokaryotes (before nucleus).
    • Eukaryotes have a nucleus separated from the rest of the cell by a membranous envelope, while prokaryotes lack a nucleus but have nucleoid, which has a large DNA molecule.
    • Cells are the structural and functional units of all living organisms, capable of carrying out all the activities necessary for life, and can create copies of themselves by growing and dividing in two.
    • Cells have three main components: plasma membrane, cytosol, and organelles.
    • The plasma membrane is a phospholipid bilayer responsible for cell morphology, movement, and transport of ions and small molecules.
    • The cytosol is the liquid portion of cytoplasm where metabolism of carbohydrates, amino acids, nucleotides, and fatty acid synthesis occur.
    • Organelles are complex intracellular locations where processes necessary for eukaryotic cellular life occur, and most cells possess endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, lysosomes, centrioles, vacuoles, peroxisomes, fibrils, microtubules, nucleus, nuclear envelope, chromosomes, and nucleolus.
