in its seed and network of branching veins in its leaves. Butterflies belong to a class of Arthropods called Insects. Butterflies undergo four life stages: egg, larva, pupa and adult. The process by which a butterfly develops through its four stages is called metamorphosis. Many organisms eat only very specific food types. Narrow food preferences can limit habitat options for an organism. The excrement of animals often reveals information about the foods that they eat. Lesson 6: The Cabbage White: From Egg to Butterfly Explore the meaning of the word “Lepidoptera,” the order of insects to which butterflies and moths belong. Explain the life cycle stages of the cabbage white butterfly. Measure the length of an egg and the length of the body of a newly hatched CWB larva. Measure and record the body length of a CWB larva every three days for three weeks. Observe food preferences of a CWB larva. Determine whether adult CWB’s prefer one color of food over another. Investigate the basic anatomy of an adult CWB. Update the organism photo card for the CWB. The cell is the basic unit of life. There are many kinds of cells. An organelle is a structure found in a cell. Cells have many organelles and only some can be seen without special tools such as stains and an electron microscope. There are basic differences between plant and animal cells. Plant cells have a nonliving cell wall. Some plant cells contain chloroplasts, which are the organelles responsible Lesson 7: Exploring Cells Observe, draw, label, and measure cells based on specific guidelines. Observe and identify certain organelles of plant and animal cells. Observe the effect of salt solution on Elodea leaf cells. Compare the structure of various cells for evidence that they are suited to their functions. Update the organism photo cards Elodea, Spirogyra, and humans.
