Trees can explode when struck by lightning. [3] [15] [16] [17] The strong electric current is carried mostly by the water-conducting sapwood below the bark, heating it up and boiling the water. The pressure of the steam can make the trunk burst. [3] [17] This happens especially with trees whose trunks are already dying or rotting.
Like all vascular plants, trees use two vascular tissues for transportation of water and nutrients: the xylem (also known as the wood) and the phloem (the innermost layer of the bark). Girdling results in the removal of the phloem , and death occurs from the inability of the leaves to transport sugars (primarily sucrose ) to the roots .
It has been argued that for plants that display foliar nyctinasty, it is a crucial mechanism for survival; however, most plants do not exhibit any nyctinastic movements. [1] Nyctinasty is found in a range of plant species and across xeric , mesic , and aquatic environments, suggesting that this singular behavior may serve a variety of ...

Melaleuca quinquenervia, commonly known as the broad-leaved paperbark, paper bark tea tree, punk tree or niaouli, is a small- to medium-sized tree of the myrtle family, Myrtaceae. It grows as a spreading tree up to 20 m (70 ft) tall, with its trunk covered by a white, beige and grey thick papery bark.
All cities have codes for marking trees. Here we’ll use Boulder, Colorado, as an example. In Boulder, when you see a dot at the base of the tree, that signifies it needs treatment for emerald ...
These ancient trees have a gnarled and stunted appearance, especially those found at high altitudes, [8] and have reddish-brown bark with deep fissures. [14] As the tree ages, much of its vascular cambium layer may die. In very old specimens, often only a narrow strip of living tissue connects the roots to a handful of live branches.
