It allows certain substances to enter or leave the cell. It can "pump" other substance into the cell against the concentration gradient or pump other "wastes" etc. out of the cell.
Two main processes are:
Passive transport processes".Some of the transport process happens "passively" without the cell needing to expend any energy to make them happen. Active transport processes :Other transport processes require energy from the cell's reserves to "power" them. Thes

What are the two principal types of molecules in plasma membranes?
The two principal types of molecules in plasma membranes are phospholipids and proteins. Phospholipids form the basic structure of the membrane, while proteins are embedded within or attached to the phospholipid bilayer and serve various functions such as transport, signaling, and cell recognition.
The plasma membranes of two adjacent cells come in contact at special sites called?
The plasma membranes of two adjacent cells come in contact at special sites called gap junctions or desmosomes. These structures are important for cell-cell communication and adhesion.
What are two lipids functions?
eg,meat,groundnut,groundnut oil,fish,dog meat.
What cell has two membranes?
A eukaryotic cell has two membranes, with the outer membrane serving as the plasma membrane that surrounds the cell and the inner membrane enclosing the organelles like the nucleus, mitochondria, and endoplasmic reticulum. This double membrane structure helps compartmentalize different cellular functions and allows for more complex regulation and control of cellular processes.
What are the functions generally consist of two componets list and describe these components?

How many membranes are around the plasma membrane?
The plasma membrane is a bi-layer, so two.

What are the two principal functions of the testis?
The two principal functions of the testis are sperm production through spermatogenesis and hormone production, mainly testosterone, which is responsible for male sexual characteristics and reproductive functions.
List the two principal functions of the testis?
sperm production and testosterone production

How many membranes does plasma membrane have?
The answer you're looking for is probably two, because a membrane consists of two layers of phospholipids, but it really depends on how the word "layer" is defined in this context.
How many times does an oxygen molecule cross a plasma membrane when moving from inside an alveolus to the hemoglobin of a red blood cell and what are the plasma membranes?
When an oxygen molecule moves from inside an alveolus to the hemoglobin of a red blood cell, it crosses two plasma membranes. The first is the alveolar epithelium's plasma membrane, separating the alveolus from the capillary, and the second is the red blood cell's plasma membrane, where the oxygen binds to hemoglobin for transport. Plasma membranes are the outer boundary of cells that regulate the passage of substances in and out of the cell.
What are the functions generally consist of two componets list and describe these components?
Large intestine,liver
What type of cellular junction that forms when a channel is formed between two adjacent plasma membrane?
A gap junction forms when a channel is created between two adjacent plasma membranes. This type of cellular junction allows for direct communication and passage of small molecules between the two cells.
What are the two principal functions of dyes in media?
The two principal functions of dyes in media are to provide color and to allow for visualization of the components within the media. Dyes are used to differentiate between different types of cells, structures, or substances present in the media.
