cellkanten

Cellkanten refers to the outer boundary of a biological cell. In animal cells, this boundary is known as the cell membrane, a flexible structure composed primarily of a phospholipid bilayer with embedded proteins. This membrane regulates the passage of substances into and out of the cell, playing a crucial role in maintaining homeostasis. In plant cells, fungi, and bacteria, the cell membrane is further enclosed by a rigid cell wall located outside the membrane. This cell wall provides structural support and protection to the cell. For plant cells, the cell wall is made of cellulose, while in fungi, it is composed of chitin. Bacterial cell walls have a peptidoglycan structure. The specific composition and properties of the cellkanten are vital for the cell's survival, function, and interaction with its environment. Variations in the cellkanten are fundamental to the diversity of life, enabling cells to adapt to different conditions and perform specialized tasks within multicellular organisms.
