Apical meristems allow the plant to grow up and down, and lateral meristem allows the plant to grow out, or laterally. Secondary meristems are usually lateral meristems and are responsible for the increase in thickness of the plant. This is because water is more vital to the plant, so the larger tube allows it to transport the water as quickly as possible. It is the outermost plant tissue and forms the epidermis. (i) Protoderm meristem: It is the outermost layer of the young growing region which develops to form epidermal tissue system. What is the Difference Between Blended Learning & Distance Learning? Open type

42. These cells are responsible for linear growth of an organ. It increases the thickness of the plant. Discover how plants accomplish this and learn about the parts of the plants that are most affected by this process. lateral meristem. Showing page 1. Lateral meristem is called the vascular cambium in many of the plants in which it is found. Meristem, region of cells capable of division and growth in plants.Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses). نسج مولدة (botany) Meristem forming a cylinder within some plants' organs (primarily stems, branches and roots) and allowing them to increase in girth (lateral growth). Lateral meristem differentiates into 2 types of tissues namely vascular and cork cambiums. Apical meristem . Types of Meristem Tissue: Depending upon their origin, meristems are of two types, primary and secondary. This type of meristem takes part in the formation of cortex, pith, endosperm and sporangia. The lateral meristem is responsible for the thickening of the vascular cambium and the cork cambium. The tissue consists of xylem toward the outside and phloem inside. Plants use lateral meristem tissue to grow in diameter as part of secondary growth. All rights reserved. It is derived from the apical meristem and is responsible for the elongation of internodes. The meristem contains cells whose sole purpose is to divide so that the plant gets bigger. Open type

Lateral meristem: located at branches to increase plant girth. Lateral Meristem. Plants that grow out, like trees and other woody plants, also contain a lateral meristem, from the Latin latus, meaning 'side.' After all, you cannot keep shoving more stuff into a tube of the same size, especially if that tube is immobile, like the bark of a tree. Intercalary meristem: Lateral Meristem. Each type consists of a hollow, vertical cylinder of cells that contribute to the thickness of woody plants. Cloudflare Ray ID: 605d5fbb3fb92ae8 's' : ''}}. So, it literally means 'the surrounding skin,' which is somewhat redundant. courses that prepare you to earn Ø Lateral meristems are the meristematic tissue present parallel to the organs in which they occur. Anyone can earn Differences in function. Tutorials Point (India) Ltd. 6,758 views. It is located in the stems and roots on the lateral side. In plants, the vascular cambium is the main route by which the stems and roots grow. Meristem, region of cells capable of division and growth in plants.Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses). When you were a child or a teen, you were responsible for much more than doing chores or listening to loud music.
