Plant Structure and Function Lab

Title: Plant Structure and Function Lab Objective(s): After doing this lab, you should be able to: ● ● ● ● ● Identify the correct plant tissues from the corresponding slides. Identify the different structures of a flower. Describe the functions of each flower structure. Describe the functions of each plant tissue. Answer the Analysis and Conclusion questions using multiple sentences. Materials: ● ● ● ● ● Flower Scissors Tape Tweezers Lab Report Procedure: Plant Tissues — Part 1 Review each image in your lab activity slide show. Identify the correct tissue or organ below based on each individual slide. Several of these choices may be used multiple times. ● ● ● ● ● ● ● phloem stoma xylem guard cells dermal ground Vascular Slide 1 a. Slide 2 vascular a. Slide 3 Guard cells Slide 4 Slide 5 a.vascular a.vascular B. dermal b.ground B.ground c. C.dermal c.dermal a. Vascular tissue b. ground B. stoma Ground d. dermal Flower Dissection — Part 2 ● ● ● ● ● ● ● Pick a flower from your yard, a public location, or somewhere in your neighborhood. Start by removing the sepals of the flower with a tweezer. If you do not have a tweezer, a small pair of scissors will also work. It may be easiest to do this if you hold the flower with your finger from below the pedicel (small stalk just underneath the flower) and begin to remove the sepals with a pair of tweezers. Using tweezers, place the sepals on the labelled printable worksheet, and tape them in place. Repeat the same procedure for the petals and pistil. Remove all but one of the stamens and tape them onto the worksheet. On your printable worksheet, you should have sepals, petals, stamens and one pistil. Take a picture of your worksheet with the flower pieces placed correctly, and save it on your computer. You will attach and submit this with your assessment questions. Data: Flower Dissection Name of Flower Component Sepal Piece of Flower from Lab Function Protects the interior flower Petals Attracts pollinators to the anthers; pleasant scent, colorful appearance, and nectar made of sugar and proteins at their base for added appeal Stamen Contains the anther and the filament (supports the anther) Pistil Holds the female gametophytes, the ovules Analysis & Conclusion — Part 3 Plant Tissues ● What are three characteristics that all species belonging to the plant kingdom have in common? 1. They are non-motile 2. They reproduce asexually by vegetative propagation 3. These are multicellular eukaryotes ● How will the numbers of stomata differ in tropical plants and desert plants? How does this help protect the health of a plant? To make sure the plants get all the sun and water they get so they won’t die If a plant's xylem and phloem become damaged, what type of damage will result within the plant? Describe the different roles on the xylem and phloem in your answer. Damaged vascular tissue could cause the fruit to not completely develop or even develop at all Why do we compare the dermal tissue of plants to human skin? Explain your answer. Because they both provide protection and both prevent water loss Would a plant be able to survive if the ground tissue was damaged? Explain your answer. To it will probably die because the tissue is helping keep alive like the food and water do for the plant ● ● ● Flowering Reproduction ● ● ● ● ● Describe how flowering plants reproduce.it will be carried by insects or some blown by the wind from one flower to another How do flowers help other organisms in our environment? it does create more carbon dioxide absorbing and more oxygen-radiating plants. Which parts of a plant are responsible for reproduction? Describe the role that each of them will play. Well the pollen needs to move to a part of the pistil and that is called the stigma Describe what occurs during the process of seed development. It will be a double fertilization and it does involve the fusion of the egg and sperm nuclei into the zygote. Based on your knowledge of flowers, why do you think most flowers are bright in color? Because there is pollinators in the flower for the color to be really bring and pretty
