Which of these is a Semipermeable Membrane (SP) and which is Selectively Permeable (SL) ?
(a) Animal bladder (b) Plasmalemma (c) Tonoplast
(d) Parchment membrane (e) Egg membrane

Explanation

To classify the membranes mentioned in the question as either semipermeable (SP) or selectively permeable (SL), we need to understand the definitions and characteristics of each type of membrane.

### Step-by-step Solution:

1. **Define Semipermeable Membrane (SP)**:
- A semipermeable membrane allows only certain molecules or ions to pass through based on their size. It restricts the movement of larger molecules while permitting smaller ones.

2. **Define Selectively Permeable Membrane (SL)**:
