Before a herbicide can kill a plant, it must be absorbed by the plant’s leaves or roots and enter a cell which possesses the metabolic pathway the herbicide targets.  This lesson follows the fate of the herbicide after it has entered the plant via leaf or root tissue, and explains the factors controlling transport of a herbicide into plant cells.  This lesson describes 1) the barriers to herbicide entry, such as the plant cell membrane, 2) the role that the herbicide’s chemical properties have on the rate of cellular absorption, and 3) experimental approaches to understanding herbicide absorption at the cellular level.

This textbook chapter makes the case for preserving desert old growth forests, and endangered species. The captive breeding program for the black-footed ferret is presented as a case study. Students learn about conservation practices they can do, such as adopting a species or garden. The chapter includes an authentic unit assessment where students produce an essay on a biodiversity topic. The resource includes a link to current news articles and a teacher's guide. This is the eighth and last chapter in the unit, Losing Biodiversity, examining the endangerment and extinction of entire species of plants and animals throughout the world due to human actions. The resource is part of Global System Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

This activity places the control of the environment under the student's control. A field starts off with a uniform light level, and thus capable of growing plants with medium-sized leaves. Students can alter the environment by "growing" a chain of mountains through the field. Students are challenged to grow the mountains to their maximum height (corresponding to the maximum change in light level on either side of the chain) while maintaining a viable population of plants on each side.

This video examines what will happen to crops as Earth's temperature rises and soils dry out because of changing climate. Students learn that a loss of soil moisture causes stress to plants, leading to crop withering. Since humans and animals depend directly or indirectly on plants for food, many social problems can be expected to arise due to the impact of climate warming on crops and the societies that depend on them.

The Changing with the Tide lesson plan is written around a role-play activity in which students learn about and act out the behavior of plants and animals in a salt marsh habitat as the tides change. An unusual feature of salt marshes is the dramatic daily change in stresses and interactions that the organisms face. On this Starting Point page, teachers can find learning goals, teaching notes and tips, teaching materials, assessment hints and references and resources dealing with this exercise. It also describes the context in which the virtual tour, another feature of the page, is best used.

Characterization of Physical, Thermal and Spectral Properties of Biofield Treated Date Palm Callus Initiation Medium

The date palm is mainly cultivated for the production of sweet fruit. Date palm callus initiation medium (DPCIM) is used for plant tissue culture applications. The present work is intended to evaluate the impact of Mr. Trivedi’s biofield energy treatment on physical, thermal and spectral properties of the DPCIM. The control and treated DPCIM were evaluated by various analytical techniques such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, particle size analyzer (PSA), surface area analyzer and ultra violet-visible spectroscopy (UV-vis) analysis. The XRD analysis revealed a decrease in intensity of XRD peaks of the treated sample as compared to the control. The crystallite size of the treated DPCIM (81.02 nm) was decreased with respect to the control sample (84.99 nm). The DSC analysis showed a slight decrease in melting temperature of the treated sample. Additionally, the latent heat of fusion of treated sample was changed by 45.66% as compared to the control sample. The TGA analysis showed an increase in onset degradation temperature of the treated sample (182ºC) as compared to the control sample (142ºC). This indicated the increase in thermal stability of the treated DPCIM. PSA results demonstrated an increase in average particle size (d50) and size showed by 99% of particles (d99) by 19.2 and 40.4%, respectively as compared to the control sample. The surface area analyzer showed a decrease in surface area of treated DPCIM by 13.4%, which was well supported by the particle size results. UV spectra of the treated sample showed the disappearance of absorption peak 261 nm in treated sample as compared to the control. Overall, the result showed that biofield energy treatment has a paramount influence on physical, thermal and spectral properties of DPCIM. Therefore, it is assumed that biofield treated DPCIM could be used as a better medium for plant tissue culture applications.

Young parents, Max and Andrea Forest, learn that their child is suffering from the genetic disorder, thalassemia. Treatment requires a lifetime commitment to whole blood transfusion and chelation therapy, both of which must be administered on a daily to weekly basis. Students read the case, answer a series of questions, and then decide how they would treat the child if they were the parents. The case was developed to introduce students to the role of metal ions and coordination chemistry in biological systems. It would be appropriate for use in courses in biochemistry, molecular biology, bioinorganic chemistry, and bioethics, among others.

In plant breeding and genetics research, plant breeders establish a hypothesis to explain how they think a particular trait is inherited, such as if it is due to one gene with complete dominance, an interaction of more than one gene, or quantitative inheritance, with many genes contributing, etc. Next the breeder sets up crosses and observes the resulting progeny to test that inheritance hypothesis. However, when the data is collected, oftentimes the plant breeder discovers the number of plants observed in each class is not exactly what was expected from the hypothesis. The question then is how do plant breeders determine if the data is close enough to what they expected to determine the hypothesis is supported or not? Following a tomato disease resistance example in this lesson, you will learn a simple statistical test that breeders can use to conclude if the experimental data supports their hypothesis of single gene, completely dominant inheritance.This lesson is written for undergraduate and graduate students studying plant breeding, as well as agriculture professionals unfamiliar with the use of the chi-square analysis.

In this lesson, from Science NetLinks, students will get acquainted with diverse forms of life by using modern biological classification systems to group animals that are related. Students will learn about basic scientific groupings like genus, species, mammals, fish, birds, amphibians, and reptiles. One of the websites featured in this lesson allows them to pair different vertebrate animals and learn more about their common traits. By doing this, students will begin to classify organisms in a more sophisticated way.
