Study Notes
Cells are the fundamental building block of life, and they play a crucial role in the structure and function of living organism. In this article, we will discuss the structure, function, and organelles of cells, focusing on the cell membrane and cell division.
Cell Structure: Cells are surrounded by a structure called the cell membrane, which serves as a clear boundary between the cell and its environment. The cell membrane is composed of a lipid bilayer and proteins, and it functions as a selectively permeable membrane, permitting the entry of selective materials in and out of the cell according to its requirement. The cell interior is a busy and crowded place, and it is packed full of cellular machinery and structural elements called organelles.
Cell Function: Cells have various functions, such as energy production, protein production, lipid production, and DNA storage. One example is the mitochondrion, commonly known as the cell's "power plant". The cell membrane and organelles work in coordinated ways to maintain homeostasis and adjust to the various needs of the cell.
Cell Organelles: Organelles are dynamic, changing size and shape to maintain homeostasis and adjusting to the various needs of the cell. They are membrane-bound structures found within a cell, and they have specialized functions. Some of the basic human cell organelles include:
- Nucleus: DNA storage.
- Mitochondrion: energy production.
- Endoplasmic Reticulum (SER and RER
