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?

Activity 82: The Cells of Producers

Vocabulary

ProducerConsumer

Photosynthesis – the process of using sunlight to convert water and carbon dioxide into glucose (energy) and oxygen.

Botany – the study of plantsChloroplast

Getting Started

Read the Introduction on page E-54Read through the procedure on page

E- 55-6.

Page 4: 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 does the plant get water from the soil to the leaves?

How does the plant get enough light?

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

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!!!

Review of Photosynthesis

Talk to the person across from you or next to you and review the equation for photosynthesis.

How are the 4 producer cells different?

Hint! Think about which part of the plant each cell belongs to! (Stem, Root, Leaf, Flower)

1a. We observed:◦Chloroplasts, ◦cell wall, ◦cytoplasm, ◦vacuole

1b. Nuclei and cell membranes were not seen

◦Nuclei are too small◦Cell walls are clear and

up against the cell wall

Page 16: 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?

2. All of the cells contained Cytoplasm, vacuoles, and cell walls

◦-chloroplasts are not visible in the onion skin

◦The cell walls and water pressure in the vacuoles help to support the plant.

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.

Page 18: 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?

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.

Page 19: 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?

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!
