Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces, often against gravity, due to the adhesive and cohesive forces between the liquid and the surrounding surfaces. This phenomenon is crucial in various natural and technological processes, such as the movement of water in plants and the functioning of ink pens.

External forces are influences originating outside a system that can affect its behavior, performance, or structure. They play a crucial role in fields like physics, economics, and business, determining how systems interact with their environments and adapt to changes.

Adhesive forces are the attractive interactions between dissimilar substances, which enable materials to stick together. These forces are crucial in various applications, from everyday adhesives to biological systems and industrial processes, influencing phenomena like wetting, coating, and bonding.

Cohesive forces are the intermolecular attractions that hold molecules of the same substance together, playing a crucial role in the physical properties of liquids. They are responsible for phenomena such as surface tension and the formation of droplets, significantly influencing how substances interact at a molecular level.

Plants are multicellular organisms that primarily produce their own food through the process of photosynthesis, converting sunlight into chemical energy. They play a crucial role in ecosystems by providing oxygen, food, and habitat, while also contributing to the carbon cycle and influencing climate patterns.
