CELL TRANSFORMATION IN TOBACCO LEAF DISKS
Young scholars work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for...
Curated OER
Plant Tissue Culture
The techniques of growing plant cells, tissues, and seeds are covered here. The main scientists working on theories and different developments through the decades of the 20th century have slides, and then specific details of the...
Curated OER
CULTURING PLANTS FROM EMBRYONIC PLANT TISSUE
Students use this laboratory exercise as a growth medium that contains the macronutrient and micronutrient needs of plants. They observe the effects of different hormones on tissue cultures and must use variations of the basic growth...
Curated OER
Cell Transformation in Tobacco Leaf Disks
Students review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...
Curated OER
Seed Germination on Gelatin
Students examine how seeds germinate in a culture. In this germination lesson students germinate seeds in gelatin and observe the growth of the plant.
Curated OER
Plant Reproduction
In this plant reproduction worksheet, students complete a crossword puzzle with 36 questions. They identify the different plant reproductive features.
Curated OER
Culturing Plants from Embryonic Plant Tissue
Student groups use lima beans to represent dicots and corn to represent monocots, soak the seeds, and separate the embryos from the cotyledons. They then place the seeds in Petri dishes in agar and observe for at least one week recording...
Curated OER
Specialty Crop Production/Orchids
Twelfth graders explore the fascinating world of orchid production including propagation, care, culture, and finishing. They complete market research and design a production schedule for an orchid crop of their choice. They write a short...
Curated OER
Plant Biotechnology: Controlling Tissue Differentiation
Students demonstrate hormonal control of plant tissue differentiation and relate this differentiation to gene expression. They explore the effects of hormones (auxin and cytokinin) on the genes that control tissue differentiation in callus.
Curated OER
Plant Biotechnology: Controlling Tissue Differentation
Students demonstrate skills of biotechnology stringent aseptic technique and statistical analysis. They describe hormonal control of plant tissue differentiation and relate this to gene expression. Students observe the effects of...
Curated OER
DNA Extraction From a Variety of Tissue Samples
Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.
Curated OER
Hormone-Induced Plant Propagation Lab using Carrot Root Cultures
Students evaluate the importance of hormones in living things. In this biology lesson, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis questions.
Curated OER
Germinating Seeds on Gelatin
Young scholars germinate seeds in unflavored gelatin to which liquid house plant food has been added. Students observe and record plant growth in this medium with a variety of variables in a number of experiments.
Curated OER
The Seed Match
Learners examine seeds and predict the plant it comes from. In this seed match lesson, students match seeds to plants and then see if their predictions are correct. Learners predict the number of seeds found in plants as well. Students...
Curated OER
Biotechnology
Students explore biotechnology through various activities. In this biology activity, students analyze its pros and cons. They study and read informative articles about biotechnology.
Curated OER
Eat Your Flowers
Students grow flowers in different soil mediums to determine the effect on flavor. In this investigative lesson students study flowers, plant them and taste them to see how they differ in different potting soils.
Curated OER
The Seed Match
Students study seeds and plants. In this science lesson, students explore seeds from various types of plants and complete a worksheet about seeds. Students discuss plants that are fruits and vegetables and where they grow.
Curated OER
Light Microscopes
Seventh graders study the parts of a light microscope, and its proper use. They identify each part and explain why it is important to know how to use this tool. They practice observing newsprint on a wet mount slide.
