How Do You Spell PLASMA MEMBRANE?

Pronunciation: [plˈazmə mˈɛmbɹe͡ɪn] (IPA)

The word "plasma membrane" refers to the outermost layer of a cell, which separates its external surroundings from its internal environment. Phonetically, the word is pronounced as /ˈplæz.mə ˈmɛm.breɪn/, where the stress falls on the first syllable "plaz" and the second syllable "mem" is pronounced with a short vowel sound. The spelling of the word is derived from the Latin term "plasma", meaning "something molded or formed", and the Greek word "membrane", meaning "thin layer".

PLASMA MEMBRANE Meaning and Definition

1. The plasma membrane is a vital component of cells in living organisms, serving as a boundary or barrier between the cell and its external environment. Also known as the cell membrane, it is a selective barrier that regulates the movement of substances in and out of the cell, maintaining homeostasis.

   The plasma membrane is composed of a phospholipid bilayer, consisting of two layers of phospholipid molecules. These phospholipids have a hydrophilic head that faces the watery extracellular and intracellular environments, while their hydrophobic tails are sandwiched between the two layers, forming a semi-permeable membrane.

   Embedded within this phospholipid bilayer are various proteins and cholesterol molecules, which contribute to the structure and function of the plasma membrane. These proteins include transport proteins that facilitate the movement of ions, nutrients, and other substances across the membrane, receptor proteins that allow the cell to respond to signals or molecules in its environment, and enzymes that catalyze essential cellular reactions.

   The plasma membrane is responsible for various vital functions, including maintaining cell shape and integrity, protecting the cell from its surroundings, and controlling the passage of substances into and out of the cell. It plays a crucial role in processes such as osmosis, diffusion, active transport, and cell signaling.

   In summary, the plasma membrane is a dynamic and essential component of cells, serving as a barrier that regulates the movement of substances and maintains the integrity of the cell.
