The false statement is "Root hairs increase the surface area of the roots to slow down absorption of water and minerals."
Explanation
## Step 1: First, we need to understand the function and structure of root hair cells. Root hair cells are specialized cells in plants that help in the absorption of water and minerals from the soil. They have long and thin extensions, which increase the surface area for absorption.## Step 2: Next, we evaluate each statement in the question in light of this understanding.### Statement 1: Root hair cells do not contain any chloroplasts as they are underground.This statement is true. Root hair cells are located underground and do not participate in photosynthesis, which is the primary function of chloroplasts. Therefore, they do not contain chloroplasts.### Statement 2: Root hairs increase the surface area of the roots to slow down absorption of water and minerals.This statement is false. The purpose of root hairs increasing the surface area is to speed up, not slow down, the absorption of water and minerals.### Statement 3: Root hairs increase the surface area of the roots to speed up absorption of water and minerals.This statement is true. As mentioned earlier, the increased surface area due to root hairs facilitates faster absorption of water and minerals.### Statement 4: Root hair cells are a specialised cells.This statement is true. Root hair cells are indeed specialized cells with a specific function of absorbing water and minerals from the soil.
