What are the people that direct the planes away from the runway called with the orange cones?
The people who direct planes away from the runway using orange cones are known as "ramp agents" or "ramp marshals." They are responsible for guiding aircraft to and from the terminal gates, ensuring safe and efficient movement on the ground. The orange cones serve as visual aids to help pilots navigate the taxiways and parking areas.
What happens after nerve damage to rods and cones in eye?
Nerve damage to rods and cones in the eye can lead to vision impairment or blindness, depending on the extent of the damage. Rods and cones are responsible for detecting light and color, so damage to these cells can result in decreased visual acuity, loss of peripheral vision, or color blindness. Treatment options may include managing underlying conditions, using visual aids, or undergoing surgical procedures, depending on the specific situation.
What is crackling of pine cones?
The seeds in pine codes are attached to the little tabs that separate and open as the mature cone dries. At some point, the tab, with seed, breaks off and glides some distance from where it fell. Some will fall directly under the tree, some will cross and land under the tree, but some will spread out away from the shade of the tree. If a seed falls on suitable ground, a new tree can sprout and grow, some distance from the parent tree. At a rate of feet, meters, etc, per year, the trees advance into burned over or otherwise disturbed and available soil.
Where does reproduction take place in gymnosperms?
Gymnosperms (meaning "naked seeds") are seed-bearing plants that don't produce flowers, instead they have male and female reproductive organs mostly in the form of cones. Their microsporophylls release pollen into the air to make available to the ovule, in the megasporophylls causing fertilization. Their seeds develop without a protective covering of ovary wall. Conifers (like pines, redwoods, and fir), gingkos, seed ferns, cycadeoids, and cycads are gymnosperms. Hope this is helpful!
What plant reproduces sori and a prothallus?

What is the reproductive organ for gymnosperms?
Gymnosperms reproduce using cones as reproductive structures. Male cones produce pollen, which is carried to female cones by wind or insects for fertilization. The ovules within the female cones then develop into seeds.
