"Botany in Hawai‘i" discusses introductory topics of Botany through examples of the native and introduced plants found in Hawai‘i. It includes anatomy and physiology of seeds, roots, leaves, stems, fruits and flowers and covers the main plant groups from nonvascular to flowering plants. This book provides a visual reference to botanical concepts and terminology for beginners.

A knowledge of broadleaf plant parts will help the student identify plants at various stages of life.  The weed ID resource books often use technical terms to describe how the plant parts look.  It is important the student understands the technical terms in order to properly identify weed species.  Students will also practice using common weed id apps

Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of central tendency of the class data, and then graph and interpret the results.

Bring the rainforest to life in your classroom! Give your students hands-on experiences that will build their understanding of the importance of tropical rainforests and the need for protecting these valuable ecosystems. Explore topics including the water cycle in the Amazon, the life cycle of rainforest plants, rainforest conservation challenges, and more. You can use this kit to prepare your students for a field trip to the Academy's Rainforest Exhibit. Or, if you can't make it to the Academy, use the kit on its own to bring the rainforest to you! This version of the rainforest kit is for grades 4 - 8.

All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. Also in: Dutch | French | Hungarian | Spanish

In this video segment from ZOOM, Jillian explains how her simple machine uses marbles, levers, flowing sand, and a spinning wheel to water a plant.

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:

"Tropical maize hybrid, a single cross of flint and dent inbred lines, is an important crop throughout the Americas and Africa. Crop yield, however, is highly dependent on nitrogen availability, and fertilizers are therefore often necessary to increase production. Developing more nitrogen-efficient maize would not only cut costs for farmers, it would also increase crop yield and reduce environmental impacts. But how do you make a plant more nitrogen efficient? The performance and production of crops can be improved by selectively crossing individuals with desired traits. When such plants are crossed, they produce hybrids that are often bigger, stronger, and more vigorous than either of the parent plants. By carefully choosing which individuals are used in creating these hybrids, specific traits, such as nitrogen efficiency, can be selected for..."

Bunga disebut bunga sempurna jika memiliki benang sari dan putik dalam satu bunga. Sementara, bunga yang hanya memiliki satu alat kelamin saja dalam satu bunga, benang sari saja atau putik saja disebut bunga tidak sempurna.

This video excerpt from NOVA’s Making Stuff: Cleaner and accompanying demonstration introduce students to the production and importance of bioplastics, or plastics made from plant or animal products.

Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Foundation’s high school Biology FlexBook covers cell biology, genetics, evolution, ecology, botany, zoology, and physiology. This digital textbook was reviewed for its alignment with California content standards.

cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually.
Advantages and Disadvantages of cloning.

In this online activity, students will have the opportunity to push their understanding of loops to a whole new level. Playing with the Bee and Plants vs Zombies, students will learn how to program a loop to be inside of another loop. They will also be encouraged to figure out how little changes in either loop will affect their program when they click `Run`.

In these lesson plans, students will act as CSI agents investigating the mysterious pathogen that caused the massive potato crop failure and resultant Great Famine of 1845 in Ireland. Through a variety of seven focused activities, students will map its diffusion, experience the history of the Great Famine, isolate and test samples using PCR and gel electrophoresis, create Wanted Posters of plant pathogens and take action in communicating their concerns of chemical controls of these pathogens and the danger of repeating history.

This task was developed by high school and postsecondary mathematics and agriculture sciences educators, and validated by content experts in the Common Core State Standards in mathematics and the National Career Clusters Knowledge & Skills Statements. It was developed with the purpose of demonstrating how the Common Core and CTE Knowledge & Skills Statements can be integrated into classroom learning - and to provide classroom teachers with a truly authentic task for either mathematics or CTE courses.
