Study Notes
Cytology Overview
- Cytology refers to the study of cells, encompassing their structure, function, and behavior.
- A cytologist is a specialist who performs research and analyses related to cell biology.
Fundamental Concepts
- The cell is recognized as the smallest unit of life, essential for all biological systems.
- Cell theory highlights three core principles:
- All living organisms are composed of one or more cells.
- The cell is the fundamental unit of life.
- Cells arise solely from pre-existing cells.
Cell Types
- Prokaryotes: Simple, single-celled organisms lacking a nucleus and membrane-bound organelles.
- Eukaryotes: More complex cells that contain a nucleus and various membrane-bound organelles.
Specific Organisms
- Bacteria: A category of prokaryotic organisms that are single-celled and move utilizing flagella.
- Protists: A diverse group of generally simple eukaryotic organisms that possess a nucleus.
Notable Eukaryotic Organisms
- Amoeba: A single-celled eukaryotic organism characterized by its ability to move using pseudopods, which are temporary projections of the cell.
- Euglena: Another single-celled eukaryotic organism that moves by means of flagella, showcasing both plant and animal traits.
- Volvox: A type of eukaryotic organism that forms colonies by grouping together, capable of photosynthesis due to its chloroplasts.
Cell Movement Structures
- Flagella: Tail-like structures that propel cells, primarily seen in bacteria and euglenas.
- Cilia: Hairlike structures found on some cells (like paramecium) that facilitate movement by beating in a coordinated manner.
- Pseudopod: A form of locomotion used by amoebas, involving the extension of the cell's cytoplasm to move and capture food.
