Water pipes, formed by the walls of dead cells, ensure the efficient transport of water and solutes in the xylem of vascular plants. In elongating plant organs such as the hypocotyl, which lifts the growing tip of the germinating seedling out of the soil, the passive elongation of dead and empty protoxylem elements by surrounding live tissue maintains a functional water-conducting system. Now, Ulrich Ryser and co-workers use confocal laser scanning microscopy to investigate a new structural element in the cell wall of protoxylem cells in hypocotyls . This structural element, which contains glycine-rich proteins , is initially deposited in the corners of cells along the longitudinal axis of the protoxylem, where it is associated with the pectin polysaccharide rhamnogalacturonan I. The authors show that the polysaccharide-rich wall of living and elongating protoxylem is gradually replaced by GRP-containing cell wall material, which develops into a complicated 3D network that seems to stabilize the protoxylem. They also report that GPR-related sequences are found in many seed plants, leading them to suggest that GRP-rich walls originated early in seed plant evolution.
Hemoglobin is a protein with a combination of secondary structures, predominantly consisting of alpha helices and beta sheets. These structural elements help maintain the shape and function of hemoglobin as a globular protein.
The two types of xylem are tracheids and vessel elements. Tracheids are elongated cells that transport water and minerals vertically within the plant. Vessel elements are shorter and wider cells that are more efficient at water transport but are less structurally supportive.
Complete fertilizers typically contain three essential elements: nitrogen (N), phosphorus (P), and potassium (K). These elements are necessary for plant growth and development, as nitrogen promotes leafy growth, phosphorus supports root and flower development, and potassium enhances overall plant health and disease resistance. Other secondary and micronutrients may also be included in complete fertilizers to further support plant growth.

Secondary elements are elements that are not the main focus or priority in a system or structure. They may have a supporting or complementary role rather than being central to the overall function or design. In chemistry, secondary elements are sometimes referred to as trace elements or minor components.
The protein structure contains both alpha helices and beta sheets, which are the two main elements of protein secondary structure.
