Groups of cells that are the source of new cells form tissue called meristem. Meristem cells aren't specialized, but when they divide, some of the new cells specialize into tissues. Areas of growth that lengthen the tips of roots and stems are called apical meristems. Lateral meristems, found all along woody roots and stems, increase the thickness of these plant parts.
What else can I help you with?
In which region of a root do you find undifferentiated cells?
the undifferentiated cell is located in the ground meristem region.
Increases in stem length occur at the?
Increases in stem length occur at the apical meristem, which is a region of cell division located at the tip of the stem. This meristem is responsible for producing new cells that contribute to the growth and elongation of the stem.
Roots and shoots lengthen through activity at?
Roots lengthen through cell division at the root tip in the zone of elongation, while shoots lengthen through cell division in the apical meristem located at the shoot tip. The apical meristem is responsible for the growth of new cells and tissues in both roots and shoots, allowing the plant to increase in length.
How is the shoot apical meristem different from the root apical meristem?
The main difference betweem root and shoot apical meristem is that in case of root apical meristem dermatogen and periblem fuses at apex and give rise to calyptrogen which is responsible for the formation of root cap
What meristem does the root cap originates?
The root cap originates from the calyptrogen, which is a specialized meristematic tissue located at the tip of plant roots. The cells of the calyptrogen continuously divide and differentiate to produce the root cap, which protects the root tip as it grows through the soil.
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.
In which region of a root do you find undifferentiated cells?
the undifferentiated cell is located in the ground meristem region.
Which tissues present in the dicot stem is meristematic in nature?
In a dicot stem, there are two areas of meristematic growth. The apical meristem which is located at the tips of roots and shoots, and the lateral meristem which contributes to outward growth.
What are two types of merestemetic tissues?
Two types of meristematic tissues are apical meristem, located at the tips of roots and stems, and lateral meristem, found in the lateral regions of stems and roots. These tissues are responsible for the growth and development of plants.
What are the two kinds of meristems?
The two kinds of meristems are apical meristem, located at the tips of roots and shoots, responsible for primary growth, and lateral meristem, found in the vascular cambium and cork cambium, responsible for secondary growth in plants.
Increases in stem length occur at the?
Increases in stem length occur at the apical meristem, which is a region of cell division located at the tip of the stem. This meristem is responsible for producing new cells that contribute to the growth and elongation of the stem.
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.
What is a axillary meristem?
An axillary meristem is a type of plant tissue located in the axil of a leaf. It is a dormant or active region of cell division that can give rise to new stems, leaves, or flowers. Axillary meristems are responsible for branching and overall plant architecture.
Roots and shoots lengthen through activity at?
Roots lengthen through cell division at the root tip in the zone of elongation, while shoots lengthen through cell division in the apical meristem located at the shoot tip. The apical meristem is responsible for the growth of new cells and tissues in both roots and shoots, allowing the plant to increase in length.
What is the site of primary growth for plants?
one answer: cell growth, which is caused by photosynthesis.
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.
Why is the epicotyl important in a plant?
EPICOTYL-shoot apical meristem is located here ; it is the part of the stem axis that extends above the cotyledons in some seeds.
