Vascular Tissue in Celery Name_________________________________

1. Write observations about the celery stalk that Ms. Henriksen gives you.

2. Label each observation as Quantitative or Qualitative.3. Make an inference for why your think the celery looks the way it does.

Question: How does a plant get water from the bottom of the plant up to its leaves?

Complete the following procedure.

Partner 1 : Color preparer

LS27

1. Get two cups and fill them with ~_____________mL of water.2. To one cup add enough food coloring to make the water a deep color. Do not add so much that

the liquid does not allow light to pass through. ~10-15 drops should be plenty!3. To the second cup add enough of a different food coloring to make the water a deep color. Again

do not add too much!4. Bring the cups to your partner at your work space.

Partner 2: Celery preparer 1. Get a piece of celery and cut about 2cm off the end so that any dead cells

are removed. Be careful with the sharp objects and make sure that only one person is handling the celery and the knife at a time. DO NOT have one person hold while the other cuts.

2. Cut up the stem vertically for about 4 inches. This should be enough that the stem can be split so that each half can fit in a different cup. DO NOT cut all the way to the top. The less you need to cut the better!

3. After cutting, put the celery into the two colored beakers that your partner has prepared. See photos on the right.

1. Draw and label your experimental set-up!

2. Label the cups with your names and class period and put them where your teacher tells you to.

3. Clean up any mess and return all supplies to their designated place in the classroom. Remember to return the items CLEAN!

Day Two: Vascular Tissue in Celery

1. Write observations about the celery stalk that you set-up yesterday.

2. Draw the results of the experiment.

3. Cut your celery stem just above where the split you made yesterday stops.

Cut here

4. Observe the leaf stem that you just cut. Label the picture on the right to show the parts that are more colored than others and what color they are.

Enrichment: Decide if celery is a monocot or a dicot.

Flowering plants are divided into monocots (or monocotyledons) and dicots (or dicotyledons). This comparison examines the differences in the leaves, stems, flowers and fruits of monocots and dicots.

Do some research!

1) Describe the differences in seed structure between monocots and dicots.

2) Use the chart on the left to decide if celery is a moncot or dicot. Give two pieces of evidence for your decision.

Remember: You can only see the stem and the leaf.

Dicots

3) On the left is a picture of a celery flowers. Count how many petals are on each flower.

___________________________

4) Does this match the classification (monocot or dicot) you decided for #2? Explain.

5) Look up a picture of another flower and use it’s characteristics to decide if it is a monocot or a dicot. Explain your observations and reasoning.
