Question

The model shows a type of cell.



Which best describes the function of the structures that are labelled P and L?
A.
Structure P controls what enters and exits the cell, and structure L makes food for the cell.

B.
Structure P holds all the parts of the cell, and structure L provides rigid support for the cell.

C.
Structure P makes food for the cell, and structure L stores the genetic instructions for the cell.

D.
Structure P creates the energy for the cell, and structure L controls what enters and exits the cell.

To determine which option best describes the function of the structures labelled P and L, we need to consider the typical functions of key cellular structures. Without the visual reference of the model, we can interpret the common roles of cellular components.

1. **Structure P** could represent the mitochondria, which create energy for the cell, or it could represent chloroplasts which are responsible for photosynthesis in plant cells.

2. **Structure L** likely refers to the cell membrane or plasma membrane, which indeed controls what enters and exits the cell.

Based on these typical functions:

- **Option A** suggests that P is a membrane and L is a chloroplast or similar structure, which is not common.
- **Option B** suggests that P is the cytoplasm or similar, and L is the cell wall, which typically applies to plant cells.
- **Option C** suggests that P is a chloroplast (making food) and L is the nucleus (storing genetic instructions).
- **Option D** suggests that P is a mitochondrion (creating energy) and L is a membrane (controlling entry and exit).

Given the typical cellular functions, **Option D** seems to be the most suitable if P is the mitochondrion and L is the plasma membrane:

**A. Structure P controls what enters and exits the cell, and structure L makes food for the cell.**

**B. Structure P holds all the parts of the cell, and structure L provides rigid support for the cell.**

**C. Structure P makes food for the cell, and structure L stores the genetic instructions for the cell.**

**D. Structure P creates the energy for the cell, and structure L controls what enters and exits the cell.**

Thus, the correct answer is **D: Structure P creates the energy for the cell, and structure L controls what enters and exits the cell.**
