But, when a plant is infected and the conditions are favorable, the ...
Within the periderm are lenticels, which form during the production of the first periderm layer. Since there are living cells within the cambium layers that need to exchange gases during metabolism, these lenticels, because they have numerous intercellular spaces, allow gaseous exchange with the outside atmosphere.
The 90-day challenge asks people to choose 10 healthy activities to do every day. These activities address both physical and mental health. Experts say the challenge can help people form healthy ...
Complementary cells are a mass of cells in plants, formed from the cork cambium at the position of the lenticels. It is a group of loosely arranged cells that aid in gaseous exchange through cork . [ 1 ]
The endothelium is involved in the formation of new blood vessels, called angiogenesis. [11] Angiogenesis is a crucial process for development of organs in the embryo and fetus, [ 12 ] as well as repair of damaged areas. [ 13 ]
