The conducting cells during spring season transport greater quantity of water and other nutrients to support active growth hence they become larger and more prominent, during autumn season the growth retards hence supply of water and minerals also reduces leaving the conducting cells smaller in size. thus the seasonal growth patterns are reflected in the conducting tissue causing rings in their trunk every year.

What plants grow on the trink of the trees?
Lichens, mosses and fungi grow on the trunk of trees.
Why do tropical hardwood trees have small spacing between their annular rings?
In the tropics trees do not stop growing. they grow at a constant speed throughout the seasons because in the tropics it is alsways hot and humid. Tropical trees do not have "annual growth rings" per se, meaning that the rings seens in a cross section are just growth rings (not annual ones). This is in contrast to trees that grow in the temperate zones that have 4 well defined seasons. In these zones the trees do not grow in winter. In the spring, with new growth, the cambium layer of the tree trunk puts out new xylem and phloem cells which form a new "annual ring" over the cells which stopped growing during winter. These are genuine "annual rings" and tropical trees do not have these because they do not experience periods of growth and non-growth.
How trees grow fatter?
A trees trunk will grow 'fatter' if it gets plenty of water. The more water the bigger ring of growth for the tree for that year.
What is exogenous trees or endogenous trees?
Exogenous trees grow in width by forming a new layer of wood under the bark. Endogenous trees grow by forming new fibres within the trunk interspersed with the old fibres.
When you remove a portion of a tree root does the root continue to grow?
If the branch of trees has been cut then it will tends to grow but if trunk is comletly cut the it will never will grow
Why are tree trunks cylindrical?
The tree trunks are cylindrical because they grow from the center and outwards. They grow uniformly and this is evident from the rings when the trees are cut.
Which one is bigger grass or trees?
Trees. Trees tend to grow much taller than grasses do because of their woody "stem" or trunk, which can hold a lot more weight than the stem of grass. Even bamboo, which is a type of grass, cannot grow as tall as most trees can.
Is the vanda sanderiana live on land?
The Vanda Sanderiana also called Waling-waling does not grow in land, they grow in the trunk of trees this tree is called the dipterocarp tree.
Why are fir and pine trees commonly used for tree ring analysis?
Fir and pine trees are easy to work with because they have clear rings and they grow quite old
How does photosynthesis help trees grow?
the system of photosynthesis helps trees grow by having chlorophyll absorb water carried from the stalk of a leaf or a tree trunk and using the sun's light as a power source turining the nutrients into glucose or sugars
Are camellias shrubs or trees?
They can be either. If the plant is allowed to grow freestanding with a single trunk it will become a tree, if it is grown multi-stemmed or trained against a wall it will grow as a shrub.
What is the link between trees and rainfall?
every tree needs water to grow, more rainfall more trees!
