What is the correct sequence of zones in a longitudinal section of a root from the bottom up?
zone of cell division-zone of elongation-zone of maturation
What are the three growth zones of roots?
This is the organization of roots from the base closest to the plant itself to the tip of the root: zone of maturation - cells specialize to carry particular functions (root hairs present) zone of elongation - rows of newly produced cells elongate zone of cell division - new cells being produced root cap - covers the growing tip
What portion of a root gets elongated?
The zone of elongation occurs when the cells in this zone stretch and lengthen as small vacuoles within the cytoplasm coalesce and fill with water. One or two large vacuoles occupy almost all of the cell volume in fully elongated cells. Cellular expansion in this zone is responsible for pushing the root cap and apical tip forward through the soil.
Difference between height of a tree and depth of a tree and level of a tree?
The height of a tree is the longest path from the root to a leaf, counting the number of edges. The depth of a tree is the longest path from the root to a leaf, counting the number of nodes. The level of a tree refers to the depth of a node with respect to the root, where the root is considered to be at level 0.
Four regions of a root in a longitudinal section?
yaaaaa.... I HAVE NO IDEA AASK SOMEONE ELSE!!!^ dumb answer.anyways, there are only three zones of a root in the longitudinal section.They are as follows:The Zone of Cell Division/MitosisThe Zone of ElongationThe Zone of MaturationThe Zone of Mitosis: Immediately proximal to the root cap is a cluster of cells that do not actively divide. This pad of cells is often called the quiescent center. These cells probably represent a reserve of cells to be recruited later in time for the meristem. As such they serve as corrections for proliferating somatic mutations. Just proximal to the quiescent center are cells that divide rapidly by mitosis, adding new cells to the length of the root. This is of course just one contribution to elongation of the root.The Zone of Elongation: Just proximal to the zone of mitosis is a zone of cell elongation. In this part of the root the newly created cells expand in their long dimension to push the meristem and root cap through the soil. The addition of the cells and their elongation are the tandem contributors to root elongation. This elongation involves resculpting the wall, growth of the cell within, a coalescence of the vacuoles to form a single large vacuole, and maturation of the organelles in these cells.The Zone of Maturation: As we keep moving proximally (away from the root apex), we find that the cells that are elongating are also differentiating. They are becoming distinguishable from each other. Some are destined to be typical parenchyma cells, while others will mature to be sclerenchyma cells.Hope this helped! :)
What is the depth of the dark zone?
the depth of the dark zone
Is a grain of rice a root?
No a grain of rice is not a root.
What is the square root of rice?
the sqare root of rice is grainfart.
What part of root are the root hair?
Root hairs are present in root hair zone. Root hair zone is located just above the root merestem zone.
What is the correct sequence of zones in a longitudinal section of a root from the bottom up?
zone of cell division-zone of elongation-zone of maturation
What does the ocean of the depth called?
neritic zone
What zone follows the zone of cells division in a root tip?
Elongation
What are the three growth zones of roots?
This is the organization of roots from the base closest to the plant itself to the tip of the root: zone of maturation - cells specialize to carry particular functions (root hairs present) zone of elongation - rows of newly produced cells elongate zone of cell division - new cells being produced root cap - covers the growing tip
What determines whether a zone is photic or aphotic?
The aphotic zone is formally defined as the depth beyond which less than 1% of sunlight penetrates.
What is DNS root hints?
A DNS root zone is the top-level DNS zone in a Domain Name System (DNS) hierarchy
What are the parts of the plant system?
Root cap, meristematic cells zone, root hair zone, mature tissue system etc.
What is the depth of the pelagic zone?
it is the open ocean. it is everything
