Intercalary meristem functions to allow for continued growth and elongation of plant organs, such as stems and leaves. It is responsible for cell division and differentiation, adding new cells to the internodes of the plant. Additionally, intercalary meristems help in wound healing and regrowth in response to damage.

What is intercalary growth?
Intercalary growth is growth that occurs in the middle of an organ or structure, rather than at the tips or edges. It allows for continued growth and elongation of structures, such as stems or roots, even after the initial growth has slowed down. One example is the intercalary meristem found in grasses, which is responsible for the continuous growth of the leaf blades.
What is the main purpose of meristem tissue?
Meristem tissue is responsible for plant growth and development. It generates new cells for primary and secondary growth, allowing plants to grow in length and girth. Meristems also play a key role in repairing damage and regenerating tissues in plants.
What cells undergo multiple divisions for apical growth or the growth at the tips of stems?
Meristem cells undergo multiple divisions for apical growth at the tips of stems. These cells are found in the shoot apical meristem and root apical meristem of plants, and continuously produce new cells for growth and development.
What is the secondary meristem that produces wood toward the inside and bark toward the outside of a tree?
The secondary meristem that produces wood toward the inside and bark toward the outside of a tree is called the vascular cambium. It is a lateral meristem responsible for the secondary growth in plants, leading to the formation of secondary xylem (wood) and secondary phloem (bark).
How is meristem culture done?
Meristem culture is typically done by excising the meristematic tissue from a plant, sterilizing it, and then culturing it on a nutrient-rich agar medium. The meristems will develop into new plants through the process of micropropagation, where they will be grown under controlled conditions in a growth chamber or greenhouse. This technique allows for the rapid production of genetically identical plants on a large scale.
What are the regions of the meristematic?
The meristematic regions in plants are the apical meristem (found at the tips of roots and shoots), intercalary meristem (located at the base of leaves or internodes), and lateral meristem (responsible for increasing the girth of stems or roots). These regions are responsible for growth and cell division in plants.

One example is the intercalary meristem found in grasses, which is responsible for the continuous growth of the leaf blades.
Why is the intercalary meristem in grasses important?
The intercalary meristem in grasses is important because it allows for rapid regrowth after grazing or cutting. It is located at the base of the leaf blades and stems, providing a continuous source of new cells for growth. This helps grasses to quickly recover and continue to thrive in their environment.
What does stomata in hydrilla plant helps?
Stomata in hydrilla plants help in regulating gas exchange, allowing for the uptake of carbon dioxide needed for photosynthesis and the release of oxygen generated as a byproduct. They also help in controlling water loss through transpiration by opening and closing to regulate the passage of gases.
Where does the majority of stem growth in plants occur?
Apical meristem.
What is the function of lateral meristem?
it helps in formation of new vascular tissues..
What kind of cells contain the DNA that decides how they take shape and function?
meristem
The tissue that enables plants to grow from their tips as long as they live is?
The meristem tissue.
What is self-perpetuating embryonic cells called?
for plants its meristematic/ meristem cells
How does the structure of cells near the apical meristem compare with the structure of cells far from the apical meristem?
Cells near the apical meristem are generally undifferentiated and actively dividing, while cells far from the apical meristem are often differentiated and specialized for specific functions. This means that cells near the apical meristem are smaller in size and have thin cell walls, whereas cells far from the meristem are larger and more specialized in structure and function. Additionally, the cells near the apical meristem may have fewer organelles and vacuoles compared to those far from the meristem.
How do you use intercalary in a sentence?
2012 is an intercalary year
What happens in meristem regions of plants?
These regions, where cells continuously divide, are where plant growth originates.
