For most plants species the radicle dies some time after seed germination, causing the development of a fibrous root system, which lacks a main downward-growing root. Most trees begin life with a taproot, [3] but after one to a few years the main root system changes to a wide-spreading fibrous root system with mainly horizontal-growing surface ...
The root system is extensive. A tiny seedling may quickly send a taproot down 60 centimeters (24 in) seeking moisture and nutrients. A mature tree may have roots extending 75 meters (246 ft). Exposed trees battered by coastal winds are often twisted into beautiful sculptural shapes resembling large bonsai, and rarely exceed 12 m (39 ft) tall.

In its broader sense, a tap-root that is thick and fleshy (due to storage); i.e. when tuberation take place in a tap-root. Pneumatophores (respiratory roots) – Part of tap-root system as respiratory roots; found in many mangrove trees. They arise from the thick, mature branches of tap-root systems, and grow upwards.

The trees grow to a height of 15–25 m (49–82 ft). The characteristic bark is smooth, powdery and greenish yellow, although new twigs are purple, flaking later to reveal the characteristic yellow. [4] It is one of the few trees where photosynthesis takes place in the bark. Straight, white spines grow from the branch nodes in pairs.
Note that banana 'trees' are not actually trees; they are not woody nor is the stalk perennial. Magnoliids (together with eudicots they are called broadleaf or hardwood trees) [ edit ]
