The endodermal cells have few transport proteins embedded in their plasma membrane .

Explanation

### Step-by-Step Solution:

1. **Understanding Endodermal Cells**:
- Endodermal cells are a layer of cells that form the innermost part of the cortex in plant roots. They play a crucial role in regulating the flow of water and nutrients into the vascular system of the plant.

2. **Role of Transport Proteins**:
- Transport proteins are specialized proteins that facilitate the movement of substances across the cell membrane. In the context of endodermal cells, these proteins are essential for the transport of minerals and nutrients from the soil into the plant.
