    Study Notes

    Cell Structure and Function

    • There are two types of microscopy used to study cells: Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM).
    • Prokaryotic and eukaryotic cells are the two types of cells, with prokaryotic cells found in Bacteria and Archaea domains, and eukaryotic cells found in Protists, fungi, animals, and plants.
    • Basic features of all cells include plasma membrane, cytosol, chromosomes, and ribosomes.
    • Prokaryotic cells lack a nucleus, have DNA in an unbound region called the nucleoid, and lack membrane-bound organelles.
    • Eukaryotic cells have DNA in a nucleus bounded by a membranous nuclear envelope, contain membrane-bound organelles, and are generally larger than prokaryotic cells.
    • Eukaryotic cells have internal membranes that partition the cell into organelles.
    • Organelles in eukaryotic cells have specific functions, such as the nuclear envelope enclosing the nucleus, the nucleolus producing ribosomal RNA, and the mitochondrion producing energy.
    • Mitochondria are sites of cellular respiration to generate ATP, while chloroplasts are sites of photosynthesis found in plants and algae.
    • Mitochondria have a smooth outer membrane, an inner membrane folded into cristae, and create compartments for energy synthesis.
    • Respiration is the process that uses oxygen to break down large molecules into smaller ones, with two types: aerobic (with oxygen) and anaerobic (without oxygen).
    • Chloroplasts contain chlorophyll and other molecules for photosynthesis, and their structure includes thylakoids, granum, and stroma.
    • Photosynthesis requires light energy, carbon dioxide, and water to produce sugars and oxygen.
