Study Notes
Cell Theory
- All cells arise from pre-existing cells.
- The cell serves as the fundamental unit of life.
- Organisms are made up of one or more cells.
Microscopy
- Scanning electron microscopes provide highly magnified images compared to light microscopes.
- Scanning electron microscopes can generate 3-dimensional images.
Cell Membrane Composition
- The cell membrane is a double-layered lipid bilayer, providing a flexible structure.
Levels of Biological Organization
- Organization of life progresses from least complex to most complex: cell → tissue → organ → organ system → organism.
Tissue Composition in Organs
- Organs are composed of multiple similar tissues that work together.
Homeostasis Regulation
- Various systems that contribute to maintaining homeostasis in the body exclude reproductive, digestive, circulatory, immune, and endocrine systems.
Red Blood Cells
- Red blood cells have a concave shape, allowing efficient oxygen transport throughout the body.
White Blood Cells and Antibody Synthesis
- White blood cells play a crucial role in fighting infections.
- High amounts of rough endoplasmic reticulum are present for the synthesis of antibodies.
Vacuole in Plant Cells
- The large vacuole in plant cells is filled with fluid, aiding in the support of leaves and flowers.
Differences Between Plant and Animal Cells
- Key structural differences include the presence of chloroplasts, centrioles, and a cell wall in plant cells.
Active Transport Mechanisms
- Two types of active transport:
- Molecular transport, which involves protein pumps for small molecules.
- Bulk transport, which moves large molecules into or out of the cell.
Lysosome Function
- Lysosomes are responsible for breaking down or recycling macromolecules within the cell.
