The video resource "Photosynthesis: Crash Course Biology #8" is included in the "Biology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Mr. Andersen shows you how to sink leaf chads in preparation for the AP Biology photosynthesis lab. An empty syringe is used to remove gas from the leaves before the lab. As the chloroplasts absorb light they produce oxygen bubbles which eventually cause the leaves to float.

Paul Andersen details the processes of photosynthesis and respiration in this video on free energy capture and storage. Autotrophs use the light reactions and the Calvin cycle to convert energy from the Sun into sugars. Autotrophs and heterotrophs use cellular respiration to convert this sugar into ATP.

Paul Andersen discusses the specifics of phylogenetics. The evolutionary relationships of organisms are discovered through both morphological and molecular data. A specific type of phylogenetic tree, the cladogram, is also covered.

Paul Andersen describes how plants and animals defend themselves against pathogens. He begins by discussing the hypersensitive response in plants as a nonspecific form of immune response. He then discusses both the humoral and cell-mediated immune response in mammals.

Hank describes why plants are so freaking amazing - discussing their evolution, and how their cells are both similar to & different from animal cells.

The video resource "Plant Cells: Crash Course Biology #6" is included in the "Biology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Paul Andersen explains how plants use hormones to respond to their environment. The following hormones are detailed; auxin, cytokinins, gibberelins, abscisic acid and ethylene.

This "Plant Growth, Development, and Response to the Environment" learning object is the from the Sumanas resource series. Sumanas offers a robust selection of content and services that are directed at enhancing the learning experience.

Paul Andersen explains how nutrients and water are transported in plants. He begins with a brief discussion of what nutrients are required by plants and where they get them. He shows you dermal, vascular and ground tissue in monocot and dicot roots, stems and leaves.

Paul Andersen explains how pigments can be separated using chromatography. He shows how you can calculate the Rf value for each pigment. He then explains how you can measure the rate of photosynthesis using leaf chads and water containing baking soda.

Paul Andersen explains the major plants structures. He starts with a brief discussion of monocot and dicot plants. He then describes the three main tissues in plants; dermal, ground and vascular. He also describes the plant cells within each of these tissues; epidermis, parenchyma, collenchyma, sclerencyma, xylem and phloem.

Paul surveys the Kingdom Plantae. He begins with a brief description of the phylogeny of land plants. He then describes the defining characteristics of plants, including cell walls, embryophytes, alternation of generation and photosynthesis. He briefly describes the sporophyte and the gametophyte.

This open course for Plants, Society, and the Environment was created under a Round Six ALG Textbook Transformation Grant. Topics include cell structure, photosynthesis, taxonomy, biomes, domestication, agriculture, and medicine.

Hank gets into the dirty details about vascular plant reproduction: they use the basic alternation of generations developed by nonvascular plants 470 million years ago, but they've tricked it out so that it works a whole lot differently compared to the way it did back in the Ordovician swamps where it got its start. Here's how the vascular plants (ferns, gymnosperms and angiosperms) do it.

The video resource "The Plants & The Bees: Plant Reproduction - CrashCourse Biology #38" is included in the "Biology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

This "Plasmid Cloning" learning object is the from the Sumanas resource series. Sumanas offers a robust selection of content and services that are directed at enhancing the learning experience.

This online article discusses supply and demand issues surrounding plastics recycling, specifically plastic water bottles. The resource, "Plastic Bottles Pile Up As Mountains of Waste Article-Student Handout" included in "Lesson 5 Non-Municipal Water" is a part of "Unit 07 Water on a Global Scale" included in Energy & Sustainability ES - Course 4.

Modern life would be impossible without plastic - but we have long since lost control over our invention. Why has plastic turned into a problem and what do we know about its dangers? The video "Plastic Pollution: How Humans are Turning the World into Plastic" is a resource included in the Environmental science topic made available from the Kurzgesagt open educational resource series.

This video is from the Khan Academy subject of Partner content on the topic of Crash Course and it covers Pollution.
