Cell Biology

The plasma membrane serves as the outermost part of the cell and separates the intracellular and extracellular environments.

The three main parts of a cell are the plasma membrane, cytoplasm, and nucleus. The plasma membrane separates the internal and external environment of the cell. The cytoplasm is the portion between the cell membrane and the nucleus, and it contains cellular organelles. The nucleus is the control center of the cell and contains genetic material.

The processes that transport substances across the plasma membrane include passive diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis.

<p>The cytoplasm is the portion between the cell membrane and the nucleus. It contains the cytosol, which is the fluid component of the cytoplasm. Organelles are structures within the cell that perform specific functions, such as the mitochondria for energy production and the endoplasmic reticulum for protein synthesis.</p> Signup and view all the answers
