A. True
B. False

Answer

To determine whether the statement "The barrier between the interior of a human cell and its external environment is known as the cell wall" is true or false, we can follow these steps:

### Step 1: Understand the Components of a Cell
- Human cells are classified as animal cells. Unlike plant cells, animal cells do not have a cell wall.

### Step 2: Identify the Correct Structure
- The main barrier that separates the interior of a human cell from its external environment is called the plasma membrane, not the cell wall.

### Step 3: Analyze the Statement
- The statement claims that the barrier is known as the cell wall. Since human cells do not possess a cell wall, this part of the statement is incorrect.

### Step 4: Conclusion
- Therefore, the statement is false. The correct answer is option B: False.
