Introduction
The most important part of the tree used in production and the timber industry is the trunk,
which we will examine in its components.
- The bark: The bark protects the tree from organisms and creepy crawlies. This part can be compared to the skin of a living being. The inner shell is used for the exchange of nutrients taken from other parts of the tree.
- Cambium: The cambium is the growing tissue of the tree, which is located under the inner bark. Sapwood: It is a soft and porous part in which a lot of sap flows. When we try to dry the wood, the evaporation of this sap reduces the volume of the board.
- If you provide a longer text, I will be happy to help you simplify it. Heartwood:
- This part has been compressed for a long time and the sap has completely penetrated it and made it strong. This part of the wood is very special because it has a beautiful color, looks nice, and does not rot easily.
- Pith: This soft part forms the center of the trunk and is the oldest part of the tree.
- Radial veins (rays): This part consists of long cells that grow along the rays of the tree’s cross-section and connect the annual rings that make up the trunk.
- Growth rings, or growth rings, are circles that form in wood as they grow in the spring and summer of each year. These rings can be used to determine how old a tree is.
- Tree bark: The bark of trees is of great value in identifying tree species, but it changes according to age, growth, and habitat, and it is difficult to describe in words. It takes a long practice to get to know the bark of trees.
- The following points should be considered when identifying tree bark:
- Can you provide more information or a longer sentence to work with?
- Characteristics of the skin include its texture, thickness, shape, color, and the way it peels off. These features can be different for different people, including the shape of the lenses in the eyes when they are young.
- Bald patches are the lateral limbs of the stalk that appear at the end of the stalk tip. Glads are broad and green organs that are arranged in an unusual arrangement on the branches of the tree and have two basic parts, the margin and the petiole.
- The width increases the contact surface of the leaf with the environment; due to its slenderness, Pehnek performs the two parts of photosynthesis and transpiration well.
- The offshoots of each plant usually have their characteristics. These are related to the genetic characteristics of the tree and possibly to natural variables such as light, humidity, and temperature.
- A branch is a woody part of a tree that is connected to, but not part of, the main trunk of the tree.
What is the most important thing about a tree?
The tree has three main parts, each of which has a specific function.
- The crown of the tree: This comprises all the branches and leaves and is the center of the tree’s food production. The leaves need light and warmth to produce food, which they obtain from the air and soil.
- The tree root: Stabilizes and anchors the tree in the soil and absorbs water and minerals dissolved in the soil, which later becomes food.
- Tree trunk: With its inner veins it is the bearer of sap and nourishment. The sap-bearing wood carries the sap from the roots to the leaves. The inner bark transports the food formed in the leaves to the branches, trunk, and roots.
Final word
Following the above points, we come to the conclusion that the most important task of trees is to produce and reduce pollutants, which is one of the most important values in human life.
The reduction of absorption, the absorption of dust, the absorption of some chemical gases and the elimination of many bacteria, unicellular fungi and harmful insects are also among the other benefits and regulate the climate of the regions.
