Answer:
seed cones and pollen cones
Explanation:
In gymnosperms, their reproductive structures include the pollen cones, which produce pollen grains or the male gametophyte; and the seed cones, which produce female gametophyte.

The publication about the effect of orthodontic forces on cytokine and receptor levels in gingival fluid investigates how this treatment can increase inflammation.
<h3>What are cytokines?</h3>
Cytokines are molecules of the immune system that act during different types of immune responses, especially in inflammatory pathways.
Cytokines are mainly secreted by helper T immune cells (T cells) and macrophages.
In this case, the publication above mentioned uses different cytokine biomarkers to test inflammatory responses after orthodontic treatment (e.g., IL-1β, TNF-α, IL-8, etc).
In conclusion, the publication about the effect of orthodontic forces on cytokine and receptor levels in gingival fluid investigates how this treatment can increase inflammation.
