Topic: Life Science -­‐ Molecules to Organisms Software: Cyber Science 3D Plant Cell Structures Lesson Overview All living things are made of cells, the basic unit of life. Some organisms are unicellular and others are multicellular. While there are many different types of cells, all cells have similar internal structures, or organelles, that carry out specific functions. In this lesson, students will learn about plant cells.

Topic: Life Science -­‐ Molecules to Organisms Software: Cyber Science 3D Introduction A cell is the basic unit of life and all living things are made of cells. The teacher will explain that although there are different types of cells, all cells have similar organelles that carry out specific functions. The teacher will explain that the students will learn about plant cells today. Activity – Plant Cell Structures 1. Open the “Plant Cell Structures” session in Cyber Science 3D. 2. Click on the “Presenter” mode at the top left corner of the screen. This will display a list of slides along the left side. 3. Follow the presentation: Click on the “Play Slides” button to pause the session at the first slide. When you are ready for the next slide, click the next slide on the list. Follow the directions on each slide and explore at your own pace. 4. Optional: At a center with textbooks and the Internet, research the functions of the organelles inside a plant cell and record your research on the "Plant Cells" worksheet. 5. Optional: Build a model of a plant cell and its organelles using a shoebox and materials found around home or at school. 6. Make a presentation to explain the functions of the organelles. This could include the model described above but can be in any format including a poster. 7. Closing
After the students make their presentations, they will discuss any discrepancies in the data. They will share their conclusions about how these cells help plants to grow and survive. Questions for Discussion 1. Based on your research, how does this cell and its organelles help plants to grow and survive? Answers will vary. Sample Answer: The plant cell and its organelles help plants to grow and survive in many different ways. Plants need cell walls to give the whole plant support and structure. Plants need chloroplasts and chlorophyll to carry out photosynthesis to produce food. Plants need vacuoles to keep their cell structure. Plants need cell membranes to regulate the flow of materials in and out of the cell, etc. 2. How is a plant cell structure similar to the structure of a whole plant? Answers will vary. Sample Answer: A plant cell has a cell wall and a whole plant can have bark to protect it. ∆Investigate Further Follow-­‐up Activity: Complete the Animal Cell Structure Activity and then compare the two types of cells.

Topic: Life Science -­‐ Molecules to Organisms Software: Cyber Science 3D Answer Key – Plant Cell Structures Activity Questions Provided in Cyber Science 3D 1. What are the main organelles of a plant cell and what are their functions? Answers will vary. Sample Answer: The cell wall is a thick, rigid layer that surrounds the cell and gives the plant its support and structure. The cell membrane, underneath the cell wall, is a thin layer of fat and protein that regulates the flow of substances in and out of the cell. The cytoplasm is a jellylike material that holds the organelles. The nucleus controls the main functions of the cell and it also contains DNA. The mitochondria are the powerhouses of the cell that convert stored energy into glucose. Chloroplasts contain chlorophyll, which use the energy from the sun to turn water and carbon dioxide into sugars (food) and oxygen during photosynthesis. The vacuole is a large fluid-­‐filled space that helps maintain the shape of the cell. The endoplasmic reticulum (rough and smooth) produces proteins and fats that are sent to the Golgi apparatus. The Golgi apparatus packages the protein and carbohydrates to get them ready to send out of the cell. Plant Structures 3
