Final answer:
Despite typically being associated with weaker plants, fibrous root systems like that of a coconut tree can support strong, tall trees by increasing water and mineral absorption. Woody trunks provide additional strength and support for the plant.
Step-by-step explanation:
The strength of a coconut tree and other strong plants with fibrous roots doesn’t solely rely on their root system. Although fibrous root systems consist of many small branching roots with no large primary root and are typically associated with weaker, smaller plants, they play a vital role in increasing the surface area for the absorption of water and minerals. Contrary to the view that fibrous roots are always linked to weaker plants, the fibrous root system in a coconut tree supports it in different ways. It enables the tree to withstand the quick drying soil conditions in coastal environments, where coconut trees commonly grow. On top of that, woody tree trunks, typical of coconut trees, are specialized for strength and support, allowing the trees to grow very tall and withstand harsh conditions.
