Unit 5: Cell Biology and Function










Unit Investigation 
Unicellular Organism: Option 1 - BacteriaOPTION 2 - Euglena, OPTION 3 - Paramecium, or OPTION 4 - Amoeba 
These models will require additional effort but are the most interesting models to make. Unicellular models will require more detailed work and there is less in-class support and materials.These models also require structures and labels for at least ten parts of the cell.

OPTION 3 - General Bacteria Cell
This is a great choice for students who may have already made a cell model at a previous school. Bacteria are prokaryotes and therefore do not have organelles. Similar to the requirements for the animal and plant cells, students making a bacteria cell model also need to make structures and label at least 11 parts of the cell.

What bacteria cell parts do I need to include? You need at least 11 different parts of the cell. Remember that bacteria do not have organelles but they do have structures! For some structures, your model needs to have multiple items. Here's the guidelines: 1 Capsule, 1 Cell Wall, 1 Plasma Membrane, 1 Infolding of Plasma Membrane, 1 Cytoplasm, 1 DNA/Chromosome (Coiled into Nucleoid), 1-2 Flagella, 10-20 Pili, 1 Basal Body, 10-20 Ribosomes, 3-5 Cytoplasmic Inclusions


Unicellular Organism: 
These models will require additional effort but are the most interesting models to make. Unicellular models will require more detailed work and there is less in-class support and materials.These models also require structures and labels for at least ten parts of the cell.

What Euglena organelles do I need to include? You need at least 11 different types of organelles. For some organelles, your model needs to have multiple structures. Here's the guidelines: 1 Nucleus, 1 Nucleolus, 1 Flagellum, 1 Endoplasmic Reticulum, 1 Golgi Apparatus, 3-5 Mitochondria, 3-5 Chloroplasts, 1 Contractile Vacuole, 1 Stigma (eyespot), 1 Photoreceptor, 10-20 Stored Carbohydrates


What Paramecium organelles do I need to include? You need at least 11 different types of organelles. For some organelles, your model needs to have multiple structures. Here's the guidelines: 1 Macronucleus, 1 Micronucleus, 1 Pellicle, LOTS of Cilia, 1 Endoplasm, 1 Oral Groove, 1 Cytosome/Gullet, 2-3 Food Vacuoles, 1 Anterior Contractile Vacuole, 1 Posterior Contractile Vacuole, 1 Anal Pore

What Amoeba organelles do I need to include?  (2018) You need at least 11 different types of organelles. For some organelles, your model needs to have multiple structures. Here's the guidelines: 1 Nucleus, 1 Cell Membrane, 1 Cytoplasm, Multiple Pseudopods, 1 Food Particle being engulfed by the cell, 1 Endoplasmic Reticulum, 3-5 Mitochondria, 3-5 Contractile Vacuoles, 3-5 Food Vacuoles, 3-5 Lysosomes, 10-20 Ribosomes

   

Do I have to buy anything to make my model?
Use items you already have to make your model. Most of our best student models have been created using materials found at home. We have many examples in class for you to see how others used things like old toys, legos, buttons, pipe cleaners, bottle caps, yarn, containers, shoe boxes, packaging materials, and more.
Correia students are a creative bunch! If you think your idea might be a bit on the wild side, please check with your teacher. It is also important to check with your teacher if you want to use any perishable items.
