This video segment from FRONTLINE/NOVA: "Harvest of Fear" looks at corn that has been genetically modified to resist one insect pest, and the multiple concerns it raises.
In this activity, students examine how to grow plants the most efficiently. They imagine that they are designing a biofuels production facility and need to know how to efficiently grow plants to use in this facility. As a means of solving this design problem, they plan a scientific experiment in which they investigate how a given variable (of their choice) affects plant growth. They then make predictions about the outcomes and record their observations after two weeks regarding the condition of the plants' stem, leaves and roots. They use these observations to guide their solution to the engineering design problem. The biological processes of photosynthesis and transpiration are briefly explained to help students make informed decisions about planning and interpreting their investigation and its results.
This essay attempts to highlight and explore the key themes and concerns raised in Eric Roach's poem 'Corn'.In so doing,this also fosters a greater appreciation of the poet and his works in general.
This illustrated guide to a corn seedling (Zea mays, Monocotyledon) is designed to help students recognize and learn the plant's individual parts. Along with an explanation of monocotyledon embryos, it includes a short description of the root system and coleoptile.
This Web page serves as a linked table of contents for the museum's supplemental resources on plant morphology. From it, you can access the following illustrated guides with a single click:The Parts of a Soybean Seedling (Glycine max, Dicotyledon), The Parts of a Corn Seedling (Zea mays, Monocotyledon), Leaf Arrangement, Leaf Type, Types of Compound Leaves, Leaf Shape, Leaf Margin, and The Parts of a Flower.
To introduce students to basic techniques of plant tissue culture and determine the effects of amino acids on growth of carrot or corn plant callus.
