The two types of lateral meristems are given as follows: There are two types of secondary meristems, these are also called the lateral meristems because they surround the established stem of a plant and cause it to grow laterally (i.e., larger in diameter). Not all plants exhibit secondary growth. Among the monocotyledons, secondary growth is not so common and is realized by the activity of peculiarly different meristems. The main difference between apical meristem and lateral meristem is that apical meristem discusses a meristem at the apex of a plant root or shoot that produces auxin and initiate the shoot or root to increase in length. Example: vascular cambium and cork cambium (phellogen). Lateral meristems consist of the vascular cambium and cork cambium and is responsible for the secondary growth of plant tissues.The secondary growth increases the girth of the plant (horizontal growth). Meristems contribute to both primary (taller/longer) and secondary (wider) growth. - Primary Growth: Cells of apical meristems divide, differentiate and develop to form primary tissues. The new tissue accumulates and results in thicker branches and stems.

The action of lateral meristem is to increase the thickness of roots and stem. the vascular cambium and the phellogen (cork cambium) is a common feature of the gymnosperms and dicotyledons. The lateral meristem is a type of meristem that occurs at the lateral areas of the plant. As a result the plant grows in length. Secondary growth occurs in gymnosperms, most eudicots, and woody magnoliids (such as the magnolia). The main function of the secondary meristem is to increase the width of the plant, which is the lateral growth. Most monocots and herbaceous plants undergo little or no secondary growth but … Secondary tissues: Tissues generated from the growth of a cambium. Lateral Meristem: Lateral meristem is the meristematic tissue in the sides of stems and roots, which is responsible for the secondary growth of the plant. Lateral meristem: Secondary growth takes place at lateral meristems. The video below provides a nice discussion of primary and secondary growth in plants (beginning at 2:20): The stem of date palm increases in girth due to the activity of apical meristem and not because of intercalary meristem and lateral meristem (involves is the normal secondary growth of dicots). Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two lateral meristems, called the vascular cambium and the cork cambium. Secondary growth is growth at the lateral meristem and increases the girth of the stem. In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue.

Lateral Meristems Responsible for Secondary Growth of the Monocotyledons: A Survey of the State of the Art Joanna Jura-Morawiec1,4 & Mirela Tulik2 & Muhammad Iqbal3 1 Polish Academy of Sciences Botanical Garden – Centre for Biological Diversity Conservation in Powsin, Prawdziwka 2, 02-973 Warsaw, Poland 2 Department of Forest Botany, Warsaw University of Life Sciences - WULS, … The present post describes the Similarities and Differences between the Primary Meristem and Secondary Meristem.
In woody roots the vascular cambium (the lateral meristem that gives rise to secondary phloem and secondary xylem) originates in the pericycle as well as in the procambium; the procambium is the primary meristematic tissue between the primary phloem and… Secondary meristems are usually lateral meristems and are responsible for the increase in thickness of the plant. Lateral meristem is found along the entire length of the stem and root except at apices. This is called primary growth. A Vascular Bundle with Cambium (Primary Meristem) Generally, this meristem occurs in the lateral regions of the plant; therefore, we call it the lateral meristem.

the increase in girth. In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue. There are two types of lateral meristematic tissue—the vascular cambium and the cork cambium.
Lateral meristem: The type of meristematic tissue that is present in the sides of roots and stems, roots and shoots, which are responsible for the secondary growth of plants, is called lateral meristem. Growth of these cells increases the girdth of the plant organ involved. Apical Meristem: Apical meristem is the meristematic tissue in the apex of stem and roots, which is responsible for the primary growth of the plant. Other articles where Lateral meristem is discussed: angiosperm: Roots: …they give rise to new lateral meristems and lateral roots.

Growth: Apical meristem: Apical meristem increases the length of a plant along its vertical axis, Lateral meristem: Lateral meristem increases the girth of a plant. Thus, it is responsible for the secondary growth of plant, i.e. Secondary meristem is a type of meristem which arises during the secondary growth of the plant.
