Study Notes
Cell Structure and Components
- The defining characteristic of an animal cell is the absence of a cell wall.
Collagen Function
- The primary function of collagen in animal cells and tissues is to provide structural support and maintain tissue integrity.
Ion Function
- Sodium and potassium play a crucial role in cells, maintaining the proper balance of electrolytes and regulating various cellular processes, including nerve impulses and muscle contractions.
Cell Composition
- Carbon, oxygen, nitrogen, and hydrogen form 95% of the cell's structure, highlighting the importance of these elements in cellular makeup.
Cell Wall Differences
- Unlike plant and fungal eukaryotic cells, which have a rigid cell wall composed of cellulose and chitin, respectively, animal cells lack a cell wall, distinguishing them from other eukaryotic cells.
