BOTANY LAB
Program Summary
A brief introduction to the study of life (biology) and the study of plants (botany) begins the lesson. The program concentrates on angiosperms (flowering plants). Participants are asked to list names of flowering plants, including flowering trees, fruits, and vegetables. The main parts of a plant and their functions are discussed. A flower dissection reveals each flower part and leads to a discussion of the processes of pollination, fertilization, and seed formation. Microscopic safety is covered before students use microscopes to view pollen grains, immature egg cells, flower petals, leaves and stems and even individual plant cells.

Tennessee Science Standards
Life Sciences 3.0 Food Production and Energy for Life 3.1 Recognize the basic requirements of all living things. 3.2 Recognize the basic parts of plants 3.1 Realize that plants and animals use food for energy 3.2 Distinguish between photosynthesis and respiration

Objectives
1. 2. 3. 4. Identify the main parts of a flowering plant and become familiar with each plant part’s function. Investigate flower parts in a virtual flower dissection. Learn why humans need plants to survive. Discover a microscopic view of plant parts, from pollen and immature egg cells to individual plant cells in flower petals and leaves.

Pre-Visit Activities
1. 2. 3. Read poems and sing songs about flowers and plants. Germinate bean seeds in a zip-lock bag between moist paper towels. Check daily to observe their progress. Place fresh-cut stems of white carnations, Queen Anne’s Lace, or other white flowers in a container of water colored with food coloring. See how the stem draws up the colored water over time and observe how the food coloring moves up the stem and to the flower. Fresh-cut celery may also be used for this experiment. For a variation on this experiment, split the flower stem lengthwise from the bottom up for about half of the stem’s length. Split the stem into two or three sections and place each section in a container with a different food coloring.

Post-Visit Activities
1. Research how many everyday products come from plants: clothing, shelter, fuel, medicines, perfumes, foods, including nuts, fruits, grains, oils, beverages, spices, herbs, and livestock feed. Research careers involving plants. Include botanists, florists, foresters, farmers, scientists and hybridizers. Collect a variety of live flowers or photographs of flowers and compare the number of flower parts in each. Classify the flowers as a dicot or monocot. Hummingbirds hover in front of flowers while they collect nectar. They use so much energy to do this that it would be like you needing to eat 150kg of hamburgers every day!
