In terms of permeability , the cell wall and plasmalemma are :

Options

A. permeable and differentially permeable respectively
B. both semipermeable or selectively permeable
C. semipermeable and differentially permeable
D. both differentially permeable

Answer

To solve the question regarding the permeability of the cell wall and plasmalemma, we can break it down into the following steps:

### Step 1: Understand the Structure of the Cell Wall
The cell wall is a rigid outer layer found in plant cells, composed mainly of cellulose. It is important to note that the cell wall is made up of dead cells and does not regulate the entry and exit of substances.

**Hint:** Remember that the cell wall is primarily for structural support and protection, and it is not selective about what passes through.

### Step 2: Determine the Permeability of the Cell Wall
The cell wall is considered to be fully permeable. This means it allows all types of solutes and solvents to pass through without any restriction. It does not differentiate between different molecules.

**Hint:** Think of the cell wall as a sieve that allows everything to pass through without filtering.

### Step 3: Understand the Structure of the Plasmalemma (Plasma Membrane)
The plasmalemma, or plasma membrane, is a living, fluid structure that surrounds the cytoplasm of the cell. It is composed of a phospholipid bilayer with embedded proteins, which allows it to perform various functions, including selective permeability.

**Hint:** The plasma membrane is dynamic and can change its shape, unlike the rigid cell wall.

### Step 4: Determine the Permeability of the Plasma Membrane
The plasma membrane is differentially permeable (or selectively permeable). This means it regulates the entry and exit of substances, allowing some molecules to pass while restricting others based on size, charge, and polarity.

**Hint:** Consider the plasma membrane as a bouncer at a club, allowing only certain guests (molecules) to enter based on specific criteria.

### Step 5: Conclusion
In summary, the cell wall is fully permeable, while the plasma membrane is differentially permeable. Therefore, the correct answer to the question is that the cell wall is permeable, and the plasma lemma is differentially permeable.

**Final Answer:** The cell wall is permeable, and the plasma lemma is differentially permeable.
