Plants and trees may seem pretty passive, but behind the scenes, their cells are working hard to put on a magic show. In this episode of Crash Course Botany, we’ll explore how the processes of photosynthesis and cellular respiration work, why they’re so critical for all life on Earth, and how they’re helping us to forge a greener path to the future.

This online article, from Biodiversity Counts, offers insight into how plants interact with arthropods. It has: an explanation of the difference between detrimental and mutually beneficial relationships; some of the chemical and mechanical modifications plants have made to attract helpful arthropods and fend off harmful ones; a detailed overview of pollination, with descriptions of seven common pollination syndromes; a detailed overview of plant defense mechanisms; and a series of questions students can ask when they see an arthropod on a plant in order to learn more about how the two are interacting.

At first glance, plant and animal cells have a lot in common: they’re both highly organized, keep their DNA tucked away in an envelope, and are kinda juicy inside. But plant cells have evolved some wild features that set them apart from animal cells. In this episode of Crash Course Botany, we’ll ask: are plants more than the sum of their cells?

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or the release of moisture to the atmosphere by plants.

The unit is designed to be completed in six or more sessions. The comprehensive curriculum materials contain information for teachers, including activity tips and an overview of the many varied reasons that plant life flourishes in one plot but not another. Students speculate on why plants are more abundant in some areas of the site than others. They list factors that might account for the differences, such as temperature, humidity, light, soil, rainfall, wind, and human or animal activity, and figure out how they can collect more data on these factors. They discuss why it might be important to take a count of all the individual plants in each plot and develop a plan for conducting the field study. A reading selection describes how scientists count plants and gives students tips for conducting their own survey. Students then count plants and record their data. Several optional activities are provided.

This is a field investigation where students observe plants in a school forest setting. Students then compare adaptations of plants from different parts of the forest.
Plant growth regulators, including auxin, gibberellin, cytokinin, abscisic acid, and ethylene, are …
Plant growth regulators, including auxin, gibberellin, cytokinin, abscisic acid, and ethylene, are investigated in this learning activity to demonstrate how these chemicals (hormones) affect plant growth and development.

This unit on plant identification helps students prepare for their fieldwork by developing their observational skills and introducing them to resources that will help them with plant identification. It's designed to be completed in five or more sessions and has comprehensive curriculum materials information for teachers, including overviews of binomial nomenclature and dichotomous keys. Additionally, a guide to finding local specialists is available online. There are optional activites and information on supplemental resources available on line.

This article, part of Biodiversity Counts, reports on the process of doing a plant inventory. The article discusses how scientists begin by marking out the plot, using colored flagging and permanent marker, why you may need to divide a plot into smaller subplots if the plants you're inventorying are smaller than trees, and some of the difficulties scientists face in the field when they're working in particularly dense areas.

Plant water relations are presented in this learning activity to help participants understand the components of water potential, explain how water moves through plants, provide examples of plant adaptations to water stress, and have a general understanding of how water potential can be measured.
Understanding the energy conversion capability of photosynthesis and the artificial nanostructured photocatalysts …
Understanding the energy conversion capability of photosynthesis and the artificial nanostructured photocatalysts contrast biotic and abiotic systems, while demonstrating the efficiency of photosynthesis compared to titanium dioxide nanoparticles in generating gas production volumetrically. The experiment results transition to a discussion of photosynthesis and the organelles within the cell where it takes place. This lesson explores light energy capture and transformation into chemical energy during photosynthesis. The lesson can lead to discussion of renewable energy conversion methods and nanotechnology, to help advance nanoscience research to solve the challenging energy issues in the future.

This original story about plants' dependence on the climate illustrates the theme of the issue of the online, free magazine Beyond Weather and the Water Cycle -- We Depend on Earth's Climate. The story is available at two reading levels, K-2 and 3-5. Four biomes are featured in a walk through a conservatory.
