Question

The cell ____________ acts as a selective barrier (or filter) regulating which compounds or particles dissolved or suspended in water are allowed to pass through the endodermis and into the vascular system.

Answer 1

Membrane

Step-by-step explanation:

A cell membrane is a protective layer for the cell, and this cell membrane is selectively permeable, meaning that is will let some things into the cell while keeping other things out.

The cell membrane is made up of a phospholipid bilayer which contains proteins which are involve in the transport of molecules in and out of the cell.

the cell membrane has several major roles:

• It protects the cells from it's surroundings.
• It maintains an internal environment that is different from it's external environment.
• It determines which particles may enter and exit the cell
