1. BES: Plant & Animal Cells May 8, 2019
Please open your journal to warm ups and take out a handout.

2. Check out your plants…
Measure all your seedlings and calculate the average for DAY 6.
Record in your data table.
Record the control measurements in your data table.

3. QUIZ over Mod 6 on Friday! 14 pt multiple choice
Need to know how a plant metabolizes a toxin
Where plants store toxins
Examples of bioremediation (we’ve discussed many!)
Function of organelles
Hierarchy of organization…atom to organism

4. Warm Up
Complete the word bank below. Write the words in correct order in your journal. No computers today!

6. NOTES: What will zinc and copper do to our plants?
Metals like zinc and copper are essential to plant survival. In small amounts, they help plants make DNA and proteins.
But, if plants get too much zinc or copper, these metals can cause problems in plant photosynthesis—the way plants make food.
Some plants have developed the ability to take up these metals without causing problems in photosynthesis.
These plants do this by storing the extra metals in their cell vacuoles— safely away from chloroplasts, parts of the cell needed for photosynthesis.

7. NOTES: Brassicas are Good Phytoremediators
Brassica plants, which include broccoli, kale, cabbage (and your Fast Plants!), are extra good at removing and storing metals. They are called hyperaccumulators.
A typical plant may take up 100 parts per million (ppm) zinc, while a hyperaccumulator can absorb up to 30,000 ppm zinc.
Plant genes control how much and where metals are stored in the plant.

8. Plant Miners: Reusing Phytoremediated Metals
Metals can even be reclaimed from some plants!
Researchers are working on new and better ways to harvest metals from plant hyperaccumulators for reuse in industry. This metal harvesting is called phytomining.
Can you imagine if the electricity in your home moved through wires made from phytoremediated copper? These plants could be the metal mines of the future!

9. Microscope Activity There is a class copy instruction sheet.
There is a student copy worksheet to write on.
Follow the directions. The monocular microscopes do not have 4th lens—so make sure check out the binocular scopes to determine magnification of the 4th lens.

10. Animal and Plant Cell Lab 5-8-19 (Write title/date in journal)
Write this question in your journal:
What do you expect will be the main differences between plant and animal cells?
Follow the directions on the class copy handout. Work with a table partner to set up all three of your slides. Do one at a time.
Label parts of the cell you can identify (2 parts for sure!)
Do all work in your journal.
Make sure to clean and dry your slides and cover slips. NO ONION OR CHARA down the drain—please put in garbage.
