The internal structure of a root hair cell includes a cell wall, a cell membrane, and a cytoplasmic extension.
Here's a more detailed look at the components of a root hair cell:
-
Shape: Roughly rectangular with a cytoplasmic extension (the root hair).
-
Cell Wall: Possesses intercellular spaces, which likely aid in the movement of water and nutrients.
-
Cell Membrane: Described as semi-permeable, controlling the movement of substances in and out of the cell. This is crucial for nutrient uptake from the soil.
The provided reference highlights the following key structural components:
- A cell wall with intercellular spaces.
- A semi-permeable cell membrane.
