Study Notes
Homeostasis in Unicellular Organisms
- Unicellular organisms uphold homeostasis through growth, environmental responsiveness, energy transformation, and reproduction.
Homeostasis in Multicellular Organisms
- Multicellular cells specialize for specific functions and communicate to achieve homeostasis.
Definition of Homeostasis
- Homeostasis refers to the ongoing maintenance of stable internal physical and chemical conditions essential for life.
Cellular Specialization
- Cells in multicellular organisms exhibit specialization, with distinct cell types fulfilling unique roles to support overall function.
Role of Cellular Junctions and Receptors
- Cellular junctions and receptors transmit signals throughout the organism, playing a crucial role in regulating bodily functions and maintaining homeostasis.
