Assigning this Quiz gives a piece of knowledge about the important medicinal plants we use in our day to day life. Secondly, enrich knowledge about the usage of medicinal plants with their secondary metabolites having the ability to cure certain disease. Thirdly about knowing or identifying the name of the plants, its uses by viewing its image. Medicinal plants give us economic importance as well as make us to usage in daily life.

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..."

Most students entering university have some experience with trees growing in a forest ecology. Most student perspectives are that of a northern hemisphere chauvinist. Several other forest structures now exist but although the "present is key to the past," deep-time fossil forests have not always been the same. The goals of the activity are (1) to introduce quantitative ecological measures to fossil benthic (autochthonous)assemblages, (2) Test assemblage relationships using diversity measures, correlation coefficients, and simple multivariate statistical analyses, and (3)Reconstruct an autochthonous fossil community in space, demonstrating that ancient community structure differs from the Recent.

Virginia Cooperative Extension Gardener Handbook is a guide for all gardeners in Virginia. It covers a variety of topics important for beginning and experienced gardeners, including soil health, native plants, and integrated pest management. This manual provides an understanding of the basics of gardening in Virginia and helps to build a strong foundation of gardening knowledge. Resources for additional reading can be found at the end of each chapter. We encourage readers to take a deeper dive into the topics that interest them and continue their learning journey.

About Virginia Cooperative Extension
Virginia Cooperative Extension (VCE) is the outreach and engagement branch of Virginia Tech and Virginia State University, Virginia’s land-grant universities. Through VCE, Extension agents, specialists, and volunteers work to share knowledge and advance the wellbeing of all Virginians. This handbook serves as the main training text for new Extension Master Gardener volunteers.
If you are passionate about horticulture, environmental conservation, or gardening education, we invite you to join us by becoming an Extension Master Gardener at https://ext.vt.edu/lawn-garden/master-gardener/Become-a-Master-Gardener.html.

"We investigated nutrition as a potential mechanism underlying the link between floral diversity/composition and wild bee performance. The health, resilience, and fitness of bees may be limited by a lack of nutritionally balanced larval food (pollen), influencing the entire population, even if adults are not limited nutritionally by the availability and quality of their food (mainly nectar). We hypothesized that the nutritional quality of bee larval food is indirectly connected to the species diversity of pollen provisions and is directly driven by the pollen species composition. Therefore, the accessibility of specific, nutritionally desirable key plant species for larvae might promote bee populations. Using a fully controlled feeding experiment, we simulated different pollen resources that could be available to bees in various environments, reflecting potential changes in floral species diversity and composition that could be caused by landscape changes..."
