Plant Stations Lab

Objectives:

a)To determine the major functions of parts of the plant.

b)To explain the evolutionary adaptation of seeds.

c)To observe the differences in taproots and fibrous roots.

d)To discover the role and importance of stomata.

Procedure:

Part A: Leaves

  1. On the bottom of your leaf, paint a thin strip of clear nail polish. Allow the nail polish to dry.
  1. Using a piece of clear tape, remove the strip of nail polish from the bottom of the leaf.
  1. Place the tape on a slide and observe under the microscope. Draw what you see. Make sure you include a title, magnification, label the stomata, and color. You should draw your picture under high power.

Analysis, Part A

  1. What is the purpose of the stomata? Which cells surround them and control whether they are opened or closed?
  1. Why do you think the stomata are located on the bottom of the leaf?
  1. When are stomata opened? When are they closed?

Part B: Stems

  1. Observe the prepared slide of the stem under the microscope. Locate the vascular tissue (red area).
  1. Draw what you observe under the microscope. Make sure you include a title, magnification, label the vascular tissue, and color. You should draw

Analysis, Part B

  1. What is the significance of vascular tissue? Why is it a major evolutionary adaptation in plants?
  1. What are the two types of vascular tissue? What is the function of each?
  1. Name the three functions of the stem.

Part C: Roots

  1. Observe the carrot and the onion. Determine which type of root each has.
  1. Draw the carrot and onion. Label the type of root. Make sure to include a title, label the type of root, and color.

Analysis, Part C

  1. Which type of root does a carrot have? How can you tell?
  1. Which type of root does an onion have? How can you tell?
  1. Name the functions of the root.
  1. Is there vascular tissue in the roots? Why or why not?

Part D: Transpiration

  1. Observe the celery. Notice how far the blue dye has traveled in the plant. Record your observations.

Analysis, Part D

  1. How has transpiration caused the water to move?
  1. If the celery had not been placed near sunlight, would the water have moved as far? Why or why not?

------

Part E: Seeds

  1. Observe the three seeds at your station: apple, coconut, and maple.
  1. Draw the maple seed. Make sure to include a title and color.

Analysis: Part E

  1. How do you think the coconut is dispersed? Why?
  1. How do you think the maple seed is dispersed? Why?
  1. How do you think the apple seeds are dispersed? Why?
  1. Are these seeds in dormancy? How do you know?

Part F: Reproduction

  1. Observe the tulip at your station. A tulip is considered a “perfect flower” because it contains both male and female reproductive structures.

Analysis: Part F

  1. Draw and label the flower using the following terms: stamen, filament anther, carpel, stigma, style, ovary, and petal.
  1. Is a tulip an angiosperm or gymnosperm? What is the major vector of pollination for tulips?
  1. What is the advantage of a flower having both male and female structures? What might be a disadvantage?
