Question

Characteristics of the plasma membrane include which of the following? Select all that apply. cellulose phospholipids and protein increased strength to the cell selective membrane

Answer 1

The right answers are: Phospholipids and protein. And Selective membrane.

(It is the cell wall which is composed by cellulose and increase strength to the cell)

Phospholipids are the essential constituents of cell membranes where, with cholesterol molecules, they are organized into a lipid bilayer in which the hydrophobic tails are oriented towards the interior of the structure whereas the polar heads form the two surfaces of the bilayer.

Biological membranes are a selective barrier between the inside and the outside of a cell or a cell compartment (organelle). They, therefore, have the property of selective permeability, which makes it possible to control the entry and the exit of the different molecules and ions between the external and the internal environment. This allows each cell organelle, but also the entire cell to have a composition different from the external one.

Answer 2

Answer;

-Phospholipids and protein

Explanation;

-The plasma membrane is composed of a phospholipid bilayer arranged back-to-back. It is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell.

- The membrane is an extremely thin layer of lipids and protein that forms outer boundary of every cell, It controls movement of molecules between the cell and its environment, Participates in joining cells to form tissues and organs and also plays important role in the ability of a cell to respond to changes in the cell's environment.
