Overview of Cell Theory and Microscopy
- Cell theory states that all living organisms are made up of cells, which can be unicellular or multicellular.
- Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
- Microscopy is the study of objects too small to be seen with the naked eye, and a compound light microscope is commonly used for viewing cells.
- The microscope has several parts, including the ocular lens, objective lens, stage, and diaphragm.
- Magnification refers to the apparent size of the specimen, while total magnification is a calculation of the ocular and objective lens magnification.
- Wet mount is a technique used to view liquid specimens on a glass slide.
- The cell membrane is a barrier that protects and holds the cell, controlling what enters and exits.
- The cytosol is a liquid that fills the gaps in the cell and contains all organelles.
- DNA contains instructions for every cell and is located within the nucleus.
- Organelles, such as ribosomes, mitochondria, lysosomes, and the endoplasmic reticulum, perform specific functions within the cell.
- Plant cells have a cell wall and chloroplasts for photosynthesis, while animal cells have a vacuole.
- Surface area to volume ratio (SA:V) refers to the amount of surface area per unit volume of an object or substance, and is important for understanding cell function and metabolism.
