The following information contains our science activity on cells.
lThe Cell: Activities
Directions: Choose one of the following activities to be completed and submitted Monday after vacation. Feel free to use materials provided in class and our online links at http://teacherscafe.com/PS83_7th/science/cells.asp
Background information:
-
A plant cell has the following organelles: a cell wall, a cell membrane, a nucleus, endoplasmic reticulum, ribosomes, mitochondria, chloroplasts, and at least one vacuole.
-
An animal cells has the following organelles: a cell membrane, a nucleus, endoplasmic reticulum, ribosomes, mitochondria, and at least one vacuole. Animal cells do not have cell walls or chloroplasts. Their vacuoles are smaller and they are more likely to have lysosomes.
-
Something to think about: Because a one-celled organism must perform all of the life functions in a single cell, its individual cell is often more complex than the cells in multicellular organisms, which often divide up the work that must be done to keep an organism alive.
Assignment Options
1) 3-dimensional Model: Construct a model of either an animal or plant cell. Model must include name labels with information on each part of the cell. Model must include information on how this cell compares and contrasts with an animal or plant cell. For example: If you make a model of an animal cell, compare and contrast it to a plant cell. If you make a model of a plant cell, compare and contrast it to an animal cell. How are these cells similar, how are they different?
2) Create a Poster: Create an illustrated poster which includes a detailed illustration of either an animal and plant cell. Poster must include labels for each relevant part of the cell. For example: If you make a model of an animal cell, compare and contrast it to a plant cell. If you make a model of a plant cell, compare and contrast it to an animal cell. How are these cells similar, how are they different?
3) Write and illustrate a childrens book: Write a book that makes it easy for a small child to understand either a plant or animal cell. The book should include labeled information on the cell you are writing about. Include information on how your cells compares to a plant or animal cell, and how it contrasts either to a plant or animal cell.
4) Internet activity: The following link, also found on our science page, takes you to a webpage dedicated to all types of cells. Use the links on the side to review the animal and plant cell structures and organelles and fill in the table below. When you have completed the table, click on the “Construct a Cell” and build all three types of cells. http://www.wiley.com/legacy/college/boyer/0470003790/animations/cell_structure/cell_structure.htm Fill in the chart below: Choose the most important
