Definition of Cambium: Characteristics, Functions, Types and Structures
Definition of Cambium: Characteristics, Functions, Types and Structures – What is the Cambium in plants and its functions? On this occasion, Seputardinding.co.id will discuss it and of course about other things that also cover it. Let's look at the discussion together in the article below to better understand it.
Definition of Cambium: Characteristics, Functions, Types and Structures
Cambium is a layer of meristematic tissue in plants whose cells are actively dividing and is responsible for plant secondary growth. The cambium structure in this plant is found in the stems and roots.
The cambium is an active cell layer that separates the xylem (wood) and phloem transport vessels (bark) is a tissue that is responsible for secondary growth in plants, especially roots and stem. This secondary growth occurs in the first season and causes an increase in girth.
The theoretical definition of the cambium is a layer of cells called the starting cells; practically, it is difficult to distinguish from the still-differentiated daughter cells, and collectively the number of cell layers is called the cambium or the zona cambial.
The form of cambium is in the form of mucus in the skin (xylem) and wood (phloem). The function of the cambium in woody stems is as a medium or pathway for nutrients from the soil to the leaves.
Cambium can only be found in dicots and gymnosperms (open seed plants) and cannot be found in monocots. Because monocot plants do not have a cambium, monocot stems do not undergo secondary growth or thickening or increasing the diameter of the stem.
In short, the notion of secondary growth is defined as the activity of the cambium in the formation of xylem and phloem. Secondary growth in plants causes the stem to grow wide as well as annual rings and pith radii are formed. Between the xylem and phloem there is a cambium whose cells are actively dividing.
Cambium growth outward will form secondary phloem and cambium growth inward will form secondary xylem so that the diameter of the plant stem will increase.
The tissue that is inside the cambium is called wood, while the outer part of the cambium is called papagan or skin. The formation of secondary transport bundles in the stem occurs due to the activity of the cambium which is influenced by the seasons.
Cambium features
The following are the characteristics or characteristics of the cambium in plants, including:
Cambium can only be found in dicot plants and open seed plants (gymnosperms), where its activity can produce cork tissue (cork or phellem, felem) outwards.
The function of the cork network is to control the entry and exit of water, to prevent attacks from pests as well as other mechanical functions.
Cambium function
Cambium is a plant structure that is hard, while the functions of cambium in plants include:
Forms wood vessels (xylem) and sieve tubes (phloem).
Transporting the results of photosynthesis in the form of glucose, oxygen and water vapor from the leaves to all parts of the plant.
Transport water and nutrients from roots to leaves for photosynthesis.
Types of Cambium in Plants
The following types of cambium in plants include:
Primary Cambium
Primary or intervascular cambium, namely the type of cambium that is located between the xylem and phloem of dicot plants and open seed plants.
Secondary Cambium
Secondary cambium, which is a type of cambium that is located on the surface of roots and stems that break due to secondary growth. The function of the secondary cambium or cork cambium is to form cork cells as a substitute for the epidermis (to the outside) and to form living feloderm cells (into).
Based on the fixed network it forms, the cambium is divided into:
Cork Cambium
Cork cambium is a type of cambium that is included in the cortex. Cork cambium activity forms cork tissue (phelem, phellem or cork) outwards. The function of the cork network is to control the entry and exit of water, preventing pest attacks, and other mechanical functions. While the activity of cork cambium in some plant species forms phelloderm (phelloderm).
Vascular Cambium
Vascular cambium or vascular cambium or commonly called cambium is a type of cambium that generally becomes a barrier between the bark (bark) of the wooden column on a tree trunk. The growth of the cambium inwards will form xylem vessels and the outer growth of the cambium will form sieve tubes (phloem, phloem).
Structure of the Cambium
Cambium is a lateral meristem because it is located in the outer region of stems and roots. For most shrubs and trees, the cambium region is a multilayered cylinder whose cross section forms a continuous ring. When the cadmium is active, it types from many layers to cells, but when it is quiescent (inactive).
The layer is considered a two-sided layer because it can generate gradients in many directions. Following perlicinal division, the cells develop into cells that remain on the outside of the agar active as a change or external cells develop so internal cells remain valid as cells exchange.
The most convincing evidence is that parallel xylem and secondary phloem are mirror images of one another. At some point, the change creates new empiric fingers which can be found in xylem and phloem. While the gearbox is ejected inside together with the thickening of the xylem cylinder.
The cell will divide into anticline fission plane so that it can enlarge the tangential area. Therefore, the gear area compensates for the breadth of the xylem cylinder. It was mentioned above that the transmission is completely cylindrical. However, small amounts of wood occur in most plants e.g. Euphorbiaaceae, succulents and most dicots, including papaya.
Here the cambium will look like a series of thin bands bounded by the original vascular bundle bundles. The limited activity of the cambium means that the files are in the form of wooden posts or wooden nets.
