These lecture slides contain open with a scenario, and chapter images, lecture outlines, and brief conceptual overviews. The slides were based on the OpenStax image slides and were developed by Asha Rao, Matthew Aderholt, and Veronica Amaku.
This lesson covers plant processes including photosynthesis, respiration, and transpiration. This represents a portion of the Introduction to Agriculture, Food, and Natural Resources (AFNR) series in Nebraska middle and high school agricultural education.
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Just as it does for humans, morning signals the time to wake up for plants. Sunlight triggers stomata, which are tiny pores on plant leaves, to open. This boosts photosynthesis by letting CO₂ in and O₂ out. Cells known as guard cells are the gatekeepers of this process, and opening the stomata requires a lot of energy. But scientists have long wondered where this energy comes from. Because while guard cells serve a key photosynthetic function, they appear less equipped than surrounding cells to perform photosynthesis. Now, researchers from HKU and ETH have discovered guard cells’ secret source of fuel. Experiments on Arabidopsis plants showed that guard cells import most of their energy in the form of sugar from surrounding mesophyll cells. Mesophyll cells contain many more chloroplasts than guard cells, helping them produce large amounts of sugar through photosynthesis..."

A POGIL activity regarding cellular respiration with an additional activity regarding the function of NAD+ in redox reactions.
The activity walks the students through the processes of Photosynthesis and Cellular Respiration.
The vomeronasal organ is also known as the olfactory organ, or the Jacobson's organ. It is an olfactory sense organ that is found in most animals. It is positioned at the base of the nasal cavity, within the roof of the mouth, and is separated into two parts by the nasal septum. It is situated close to the vomer and nasal bones, hence the name vomeronasal organ.

"Mechanical ventilation is a tricky balancing act. Ventilators involve many different settings, and a change to one nearly always causes shifts in others. This interdependence makes it difficult to pinpoint what parameters might contribute to lung injury. And this ambiguity extends to positive end-expiratory pressure, or PEEP. Although many believe that PEEP protects against ventilation-induced lung injury, a new report in the journal Anesthesiology argues that PEEP is also a source of risk. According to the report, this dual nature is the result PEEP’s key role in mechanical power. The concept of mechanical power serves to provide a unified overview of how different ventilator settings relate to the risk for ventilator-induced lung injury. In essence, mechanical power describes the intensity of energy delivered to the respiratory system during ventilation. The sum of this energy depends on everything from tidal volume to respiratory rate..."

"Although lakes cover less than 1% of the Earth’s surface, they are an essential component in the planet’s carbon cycle. But there are striking regional differences in the degree of carbon cycling that occurs in lakes, and the underlying causes aren’t well known. To improve understanding of these differences, an international research team has proposed a geographic framework to connect carbon processing at the ecosystem level with regional drivers such as climate, land cover, and human activity. Based on this framework, they’ve described two mechanisms that explain geographic differences in carbon cycling, providing new insight into the role of inland waters in the broader global carbon cycle. The first mechanism proposes that regional differences in lake carbon cycling are linked to whether water color exceeds a threshold level. Where these levels fall in relation to this threshold affects ecosystem patterns, such as lake metabolic status..."
