What is the definition of intercalary?
Definition of intercalary 1a : inserted in a calendar an intercalary day. b of a year : containing an intercalary period (such as a day or month) 2 : inserted between other things or parts : interpolated.
What does intercalary meristem do?
The intercalary meristem is found at the base of the internodes, and their main function is to provide elongation and growth of that part of the plant where they are present.
What does intercalated mean in biology?
In biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA). This process is used as a method for analyzing DNA and it is also the basis of certain kinds of poisoning.
Where is the location of intercalary meristem?
internodes
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).
What is intercalary growth?
a lengthwise growth in plants as a result of cell division in the formative tissue (meristem), located below the top of the organ—for example, in the internodes of the stalks of grasses and at the base of the leaves.
What is intercalary meristem Class 9?
Complete Answer: The meristematic tissues that are present at the base of internodes of stem and petioles of leaves are known as Intercalary meristem. The function of these tissues is to promote the growth of the plants by elongating the nodes and internodes present at the leaves and stems.
What is intercalary in plant?
The intercalary meristems are located at the internodes or the base of the leaves. The intercalary meristems help in increasing the length of the internode. This is usually seen in monocotyledonous plants. Intercalary meristems are capable of cell division, and they allow for rapid growth and regrowth of many monocots.
How does the intercalary meristem contribute to the growth of the plant?
An intercalary meristem is a primary meristematic tissue that helps a plant or tree to grow vertically by adding to its length. The cells in this meristematic region are small, totipotent, thin-walled, and full of protoplasm.
How does intercalation work in DNA?
A substance that inserts itself into the DNA structure of a cell and binds to the DNA. This causes DNA damage. In cancer treatment, DNA intercalating agents may kill cancer cells by damaging their DNA and stopping them from dividing.
What causes DNA intercalation?
Intercalating agents are hydrophobic heterocyclic ring molecules that resemble the ring structure of base pairs, and include ethidium bromide, acridine orange, and actinomycin D. Insertion of these agents distorts the DNA double helix, thereby interfering with DNA replication, transcription, and repair.
Is intercalary meristem a lateral meristem?
On the basis of their position in the plant body, meristems are grouped as apical, lateral or intercalary meristem. Stem has apical meristem in the shoot apex, intercalary meristem in nodes and lateral meristem in form of cambium in vascular bundles.
What do you understand by apical growth and intercalary growth?
The Growing Point: apical and intercalary meristems The apical dome contains apical meristems which push new leaves upward causing the grass plant to increase height and foliage. Intercalary meristems begin in the primordium and are pushed upward to become the base of each leaf blade.
What is difference between apical lateral and intercalary meristem?
The apical meristem is present in the apex of stem and roots. The lateral meristem is present in the sides of stem and roots and the intercalary meristem is present between the tip and the base of the stem and leaves. The intercalary meristem is involved in the increase of length between nodes.
What is lateral meristem?
Definition of lateral meristem : a meristem (as the cambium and cork cambium) that is arranged parallel to the sides of an organ and that is responsible for increase in diameter of the organ — compare apical meristem, intercalary meristem.
What is apical intercalary and lateral meristem?
The apical meristem, which is separated from apices due to formation of permanent tissues in between, is termed as intercalary meristem. It is intermodal in position and carries out localized growth. Lateral meristem is present along the sides and increases girth of the plant.
Which region of the molecule is crucial to intercalation?
bithiazole ring system
Which region of the molecule is involved in intercalation? Feedback: The bithiazole ring system is involved in intercalation.
Is intercalation reversible?
The term ‘intercalation’ refers to a process whereby a guest molecule or ion is inserted into a host lattice. The structure of the guest–host or intercalation compound is only slightly perturbed from the host structure and the reaction used to form the compound is reversible.
How does DNA intercalation work?
What is apical and intercalary meristem?
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).
What is the difference between apical lateral and intercalary meristem?
What is the meaning of intercalary?
1a : inserted in a calendar an intercalary day. b of a year : containing an intercalary period (such as a day or month) 2 : inserted between other things or parts : interpolated.
What is volume in science?
What Is Volume in Science? Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas.
What is intercalation?
Occurring between two others; as in a pulse tracing, an upstroke interposed between two normal pulse beats, or a neuron (intercalated or internuncial) with short processes that connect one neuron with another in a circuit or pathway. 2. In fungi, located in a hypha or between hyphal segments, not at a hyphal terminus.
What units are used to measure volume?
Updated January 27, 2020. Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas. Common units used to express volume include liters, cubic meters, gallons, milliliters, teaspoons, and ounces, though many other units exist.
