Not necessarily. Technically any stem can become the new "trunk of the tree". Its a hormonal thing. The tips of the stems and trunks are very light sensitive and can sense the tallest "trunk". The apex or tips of every trunk/stem has the same hormones, but the tallest tree trunk is active. If you were to cut off the tallest stem of a tree the second tallest limb would grow into take its place.
the roots underneath the trunk let the tree grow
Tree trunks is that trees middle position.
Yes, climbing ferns typically have weak, twining stems that require support to climb. These stems are adapted to wrap around tree trunks or other structures for stability as the fern grows upward.
It sounds like you're describing a palm tree with multiple trunks or stems growing from the base. This is a common characteristic of some palm species, where the main trunk divides into three or more separate stems as it grows. The multiple stems can give the palm tree a fuller and more decorative appearance.
tree trunks have xylem and phloem
A tree with multiple trunks is called a "multi-trunk tree."
They either store it in their trunks/stems like the baobab tree or the cactus. Or, they just need very little of it to survive.
A tree usually has fewer trunks than branches. Trunks are the main upright structure of a tree that supports the branches, while branches are the smaller offshoots that grow from the trunk.
Lichen is a combination of fungus and algae. It grows on tree trunks.
A tree with multiple trunks, also known as a multi-trunk tree, has several main stems growing from the ground. This type of tree differs from a tree with a single trunk, which has only one main stem. Multi-trunk trees often have a more bushy or spreading appearance, while single-trunk trees typically have a more upright and singular shape.
Examples of aerial stems include tree trunks, bamboo stalks, and stems of climbing plants like vines. These stems grow vertically above the ground and provide structural support for the plant as well as space for leaf attachment and nutrient transport.
A palm is a monocot (family monocotyledoneae), which is related to corn, grass, bamboo, agave, irises, yucca, etc. They do not develop rings year to year, and their stems are dramatically different from tree trunks. They do not add bulk to their trunks year to year at all, and their water transportation system is clusters of phloem and zylem packed in a pithy fibrous sheath.
