What aids the action of capillary plants?

Explanation

**Step-by-Step Solution:**

1. **Understanding Capillary Action**: Capillary action in plants refers to the ability of water to move upward through narrow spaces, such as the xylem vessels in the plant's roots and stems. This movement is crucial for transporting water and nutrients from the soil to various parts of the plant.

2. **Role of Cohesion**: One of the key properties that aid capillary action is cohesion. Cohesion is the attraction between water molecules. Water molecules tend to stick together due to hydrogen bonding. This property allows the water to form a continuous column in the xylem vessels, enabling it to rise against gravity.

3. **Role of Adhesion**: The second important property is adhesion. Adhesion is the attraction between water molecules and the molecules of the plant's xylem vessels. Water molecules adhere to the walls of the xylem, which helps to pull the water upward as more water molecules are drawn up from the roots.
