In the cross-section of a pine stem, the secretory cells primarily include resin ducts and secretory parenchyma cells. Resin ducts are specialized structures that produce and store resin, which serves as a defense mechanism against pathogens and herbivores. Secretory parenchyma cells, found in the surrounding tissue, can also contribute to the secretion of various compounds. Together, these cells play crucial roles in the plant's response to injury and environmental stress.

Resin ducts are specialized channels that produce and store resin, which serves as a defense mechanism against herbivores and pathogens. Secretory parenchyma cells may also contribute to the secretion of various metabolites and compounds. Together, these cells play a crucial role in the plant's defense and overall health.
In the cross-section of a pine stem, secretory cells are specialized cells that produce and store various substances, such as resins and oils. These cells play a crucial role in the plant's defense mechanisms, helping to deter herbivores and protect against pathogens. Resins can also help seal wounds, preventing water loss and further injury to the plant. Typically, these secretory cells are found in the phloem or parenchyma tissue of the stem.
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
Pluripotent stem cells.
The three types of stem cells in adults are hematopoietic stem cells (found in bone marrow and produce blood cells), mesenchymal stem cells (found in various tissues like bone marrow and fat, can differentiate into bone, cartilage, and fat cells), and neural stem cells (found in the brain and spinal cord, can differentiate into neurons and supporting cells).

They are needles
I have no idea, they probably just gather more nutrients for the Pine Tree. But are. by any chance, in Sacramento, and a kid, that goes to Sutter Middle School? o-o
no
There are three different types of tissue stem cells in the body. They include the tissue stem cells also known as adult stem cells, embryonic stem cells, and induced pluripotent stem cells.
They are meristematic cambium cells located in a layer just inside the bark of trees and shrubs.
hardwood,such as oak, generally absorbs less water then softwood,such as pine, because of the amount of cells in the bark/stem.
