Answer 1

The plasma membrane is made up of molecules in two layers which we call the phospholipid bilayer. The layers are made of molecules called phospholipids. They have a hydrophobic (water-fearing) tail and hydrophilic (water-loving) head.

Which part of the molecule faces out towards the cytoplasm? The hydrophobic tail

How do molecules get inside and outside the cell? Active transport or passive transport

To bring something inside the cell, it is called endocytosis

To bring something outside the cell, it is called exocytosis

Two types of transport: passive transport or active transport

Which one does not require energy? passive transport

In the one that does not require energy, the move across a concentration gradient.

They move from high concentration to low concentration.

The goal is to have the molecules evenly distributed over time on both sides of the concentration gradient.
