Short Description:
History and Science of Cultivated Plants narrates how humans transitioned from foragers to farmers and have arrived at present-day industrial agriculture-based civilization. It entails myths, historical accounts, and scientific concepts to describe how human efforts have shaped and produced easier to grow, larger, tastier, and more nutritious fruits, vegetables, and grains from wild plants. Using examples of various economically and socially important crops central to human civilization, the book describes the origin of crop plants, the evolution of agricultural practices, fundamental concepts of natural selection vs. domestication, experimental and methodical plant breeding, and plant biotechnology.

How can a tree grow in the middle of a field if no one planted it there? In this lesson, students will work to find out the answer to this question by learning how seeds are dispersed. Students will observe different types of seeds and see how they sometimes "hitch a ride" in or on animals to travel great distances. Finally, they will use the engineering design process to make models of animals that help disperse seeds. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

A simple guide to the creation of honey and resources for how the student can help the Honey bee

In this lesson, the students will learn that plants need water, air, nutrients, and sunlight to grow. This lesson results from a collaboration between the Alabama State Department of Education and ASTA. **This lesson can be taught over a three to five day period. Simply repeat the steps as the students will become more knowledgeable of the target.

This is an activity where students learn about inquiry by designing an experiment on bean plants with the goal of growing the tallest plant. Students work in groups to plan the growing conditions of the control and three experimental plants. Students collect data for about three weeks and analyze their data to see if their hypothesis is correct or not. The end product can be a report presented in a number of ways.

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:

"Chloroplasts harness sunlight to power all the processes that help plants grow. Like engines, they must carefully balance their fuel to run efficiently. In plants, that’s the ratio of ATP to NADPH, two forms of fuel produced by photosynthesis. But scientists have long known that ATP/NADPH ratios in chloroplasts fall short of the value required for plants to turn CO₂ into sugars. To find out how plants overcome this imbalance, researchers tracked ATP in Arabidopsis plants in real time using a fluorescent protein sensor. They found that immature chloroplasts in young seedlings imported cytosolic ATP for chloroplast biogenesis, using an abundance of ATP transporter proteins to do the job, but mature chloroplasts downregulated these transporters to minimize ATP importation. Instead of importing ATP to maintain fuel balance, chloroplasts exported NADPH in the form of malate..."

This article, part of Biodiversity Counts, provides insight into the important task of identifying plant specimens. The article includes a list of tools that are part of a botanist's field kit.

In this Biodiversity Counts article, students learn how to preserve their plant pressings.

In this Biodiversity Counts activity, students learn how to press and preserve plant specimens. The online page includes illustrated instructions about how to layer and maintain pressings until the specimens have dried.

This online article, from Biodiversity Counts, is a general-purpose tip sheet for using a dichotomous key. The article outlines a three step process using a tree as an example.

In this hands-on investigation, students will utilize the hydroponic method to grow a bean plant from a bean seed. Over the course of a 2 week time period, students will make detailed observations and sketches of the actual bean growth and make predictions about growth patterns over the weekend time periods. Students will create a cartoon to defend the position that plants obtain materials needed for growth primarily from air and water. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

Short Description:
This identification guide provides technical descriptions and photos for Ohio’s 21 invasive and noxious weed species. These descriptions include information on habitat, life cycle, key plant characteristics, and a summary of problematic features. Photos included in this guide present the weed species at different stages of maturity for optimal identification aid. This book also provides information on Ohio’s noxious seed law, extension guides to weed control, and a quick guide to weed regulations in Ohio law.

This activity is designed for students to discover how making observations of the environment is the key to making sound predictions. Students will also learn how both positive and negative outcomes of these predictions can affect and shape future decisions.

Return to milneopentextbooks.org to download PDF and other versions of this textNewParaInanimate Life is an open textbook covering a very traditional biological topic, botany, in a non-traditional way. Rather than a phylogenetic approach, going group by group, the book considers what defines organisms and examines four general areas of their biology: structure (size, shape, composition and how it comes to be); reproduction (including sex when present); energy and material needs, acquisition and manipulations; and finally their interactions with conditions and with other organisms including agricultural interactions between plants and people. Although much of the text is devoted to vascular plants, the book comparatively considers ‘EBA = everything but animals’ (hence the title): plants, photosynthetic organisms that are not plants (‘algae’, as well as some bacteria and archaebacteria), fungi, and ‘fungal-like’ organisms. The book includes brief ‘fact sheets’ of fifty-nine organisms/groups that biologists should be aware of, ranging from the very familiar (corn, yeast, pines) to the unfamiliar (cryptophytes, diatoms, late-blight of potato). These groups reflect the diversity of inanimate life.NewParaThis updated edition was published in July 2022 and includes corrections, revisions, additional figures, and fact-sheets for several more groups.
