PLANT PARTS AND ITS TRANSPORT SYSTEM.pptx

Xylem and phloem are the two types of transport tissue found in vascular plants. They form a complex network running throughout the plant, carrying resources to different parts and disposing of waste products.

3. ACTIVITY 2.1: PLANT PARTS AND THEIR FUNCTION

4. Let the learners do Activity 2.2: A Tale of Two Systems: Humans vs Plants Guide questions: How are the organ systems of humans and plants similar in terms of food digestion? How are they different? . Are there any similarities and differences between human organ systems working together and plant parts working together? Why is it important to take care of plants?

5. ACTIVITY 2.4 : Plant Transport System in Action

6. PROCEDURE: 1.Add a small amount of warm water to a cup (about 3cm). The stronger the color, the more obvious the results will be. 2.Cut off the bottom of the celery to separate the sticks. Take a moment to look closely at the end of the celery and its features. Then place the bottom of the celery stick in the colored water (this would be the wider and less curved end). 3. Leave the cup with the celery in a safe place and note the time. Some water dyes will work in as little as 30 minutes, but sometimes for best results, it’s better to wait overnight.

7. 4.Come back later or the next day to examine your celery. Do you see any obvious color changes in color? Carefully take the celery out of the water and place it on some paper towels. Wipe off any colored water on the outside of the celery. 5.Hold the celery at the bottom with your thumb sitting inside the curve. Carefully bend it backward until it breaks. Pull back the broken bit to reveal the tubes inside the celery. If you pull it carefully, you can remove it all the way to the top!
