Question

How can i remember the cell membrane?

Answer 1

The cell membrane is a phospholipid bilayer that regulates what can pass through and what stays on one side. Proteins help transport substances across the membrane.

Step-by-step explanation:

The cell membrane is a phospholipid bilayer that surrounds all cells. It regulates what can pass through and what stays on one side of the membrane. Here are some key points to remember:

1. The cell membrane is made up of a double layer of phospholipids. Phospholipids have a hydrophilic ('water-loving') head and two hydrophobic ('water-hating') tails.
2. Proteins are embedded in the phospholipid bilayer of the cell membrane. These proteins help transport substances across the membrane.
3. The cell membrane is selectively permeable, meaning it allows certain substances to pass through while preventing others from crossing.

By understanding these key concepts, you can better remember and understand the structure and function of the cell membrane.

Answer 2

Answer: Honestly I remember it by thinking of something from daily life.

Step-by-step explanation:

Think of it as a concrete wall. It's ridged, hard, and you really can't get by it. Only special things can break it. Think of those special things as the nutrients for the plant.
