Study Notes
Cell Structure and Functions
- Nucleus: Control center of the cell, contains genetic material (DNA), and regulates gene expression.
- Organelles: Specialized structures within cells that perform specific functions like energy production and protein synthesis.
- Cell Membrane: Outer boundary of the cell that controls the passage of substances in and out.
- Prokaryotic vs Eukaryotic Cells: Prokaryotic cells are simpler with no true nucleus; eukaryotic cells are complex with membrane-bound organelles.
- Mitochondria: Organelle responsible for energy production via cellular respiration in eukaryotic cells.
Key Functions of Organelles
- Ribosomes: Responsible for protein synthesis in cells.
- Endoplasmic Reticulum: Involved in protein synthesis and processing.
- Golgi Apparatus: Packages and modifies proteins for secretion or transport within the cell.
Cell Theory Principles
- All living organisms consist of one or more cells.
- Cells cannot arise spontaneously from non-living matter.
Characteristics of Cells
- Cells are the fundamental structural and functional units of living organisms.
- Common features of cells include a membrane, cytoplasm, and genetic material.
Importance of Various Techniques
- Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM): Techniques used to study ultrastructure and surface morphology of cells.
- Cell Culture: A method of growing cells in a controlled environment for research and study of cell behavior.
- Immunofluorescence: Technique using fluorescently labeled antibodies to visualize specific proteins within cells for the study of cellular processes.
- Flow Cytometry: Analyzes and sorts cells based on physical and chemical properties using lasers and detectors.
- Molecular Biology Techniques: Includes PCR and DNA sequencing to study cellular DNA, RNA, and gene expression.
- Live Cell Imaging: Observes dynamic cellular processes in real-time using methods like confocal microscopy.
Miscellaneous
- Cells can generate energy through cellular respiration (mitochondria) and photosynthesis (in plant cells).
- Ribosomes and endoplasmic reticulum work together for essential protein synthesis.
- Live cell imaging is critical for understanding cell behavior and responses to stimuli.
