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?

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.

What plants need for photosynthesis: Water Light Carbon Dioxide

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

Parts of a Plant:

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

Getting Started Read the Introduction on page E-54 Read through the procedure on page E- 55-6.

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

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!!!

What Should I Have Seen???

What I Should Draw: Onion Cell

What I Should Draw: Celery Cell

What I Should Draw: Elodea Cell

What I Should Draw: Spinach Cell

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

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

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

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

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.

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.

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!
