In a cross section of a pine stem, the secretory cells primarily include resin ducts and secretory parenchyma cells. 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.

What are the secretory cells in the cross-section of a pine stem?
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.
In cross-section of a pine stem what are secretory cells?
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.
What do pine pollen grains fertilize?
Pine pollen grains fertilize the ovules of pine trees, specifically within the female cones. When the pollen is carried by the wind to the receptive ovules, it germinates and grows a pollen tube, allowing sperm cells to travel down and fertilize the eggs. This process is essential for the production of seeds in pine trees, contributing to their reproductive cycle.
