1. Activity 82: The Cells of Producers
Challenge How are the cells of plants, such as producers, different from the cells of consumers, such as animals?
How do plant structures relate to their function as producers?

2. Vocabulary Producer Consumer
Photosynthesis – the process of using sunlight to convert water and carbon dioxide into glucose (energy) and oxygen.
Botany – the study of plants
Chloroplast – the organelle in plant cells that contain the light-absorbing green pigment chlorophyll; it is where photosynthesis takes place.

3. What plants need for photosynthesis:
Water
Light
Carbon Dioxide

4. Structure of a Typical Plant
How does the plant get water from the soil to the leaves?
How does the plant get enough light?
Structure of a Typical Plant
Although it is easy to see plant structures with the naked eye, it is also true at the microscopic level.
We are going to investigate how the cellular structure of plants relates to their ability to produce food through photosynthesis

6. Parts of a Plant:

11. Making a Wet-Mount Slide
Place 2-3 drops of liquid in the center of the slide
Add specimen to the liquid
Add cover slip at a 45 degree angle

12. Getting Started Read the Introduction on page E-54
Read through the procedure on page E

13. You will be preparing slides and looking at:
Elodea
Spinach
Celery
Onion

14. In your notebooks: Glue in the Cell Drawings Handout
Remember tomorrow – Cell drawings need to be neat and as accurate as possible. Do not scribble!!!

16. What Should I Have Seen???

17. What I Should Draw:
Onion Cell

18. What I Should Draw:
Celery Cell

19. What I Should Draw:
Elodea Cell

20. What I Should Draw:
Spinach Cell

21. How are the 4 producer cells different?
Hint!
Think about which part of the plant each cell belongs to! (Stem, Root, Leaf, Flower)

22. Analysis Questions Page E- 56
In your tables work on Analysis Questions:
1-3 and 5
Analysis Questions Page E- 56

23. 1b. cell membranes were not seen
1a. We observed:
Chloroplasts,
cell wall,
Nucleus
1b. cell membranes were not seen
Cell membranes are clear and up against the cell wall
Vacuole
Cytoplasm

24. 2. All of the cells contained Cytoplasm, vacuoles, and cell walls and nuclei
-chloroplasts are not visible in the onion skin

25. 3a. The animal cell is a consumer
3a. The animal cell is a consumer. Animal cells need to get their energy from food, such as starches, and sugars made by plants
3b.nucleus, (and nuclear membrane) cytoplasm, and cell membrane would be in both types of cells
3c. Chloroplasts are most important in food production/photosynthesis.

26. 5a. Leaves and stems are exposed to sun year-round, so they are likely to absorb sunlight. The leaves are the primary photosynthesis factories of the plant, but other green parts can also carry out the process. The non-green parts do not photosynthesize. Roots do not receive sunlight and flowers serve for reproduction.

27. 5b. The cells of the celery stem, elodea leaf and the spinach would be expected to carry out photosynthesis based on the presence of the chloroplasts. 5c. Chloroplasts are seen only in cells that absorb sunlight and carry out photosynthesis. SO, plant cells contain organelles that relate to their unique role as producers!
