Note: The picture above of the cell with the flagellum was created entirely by CJ Smith, the author of this science portfolio. Also note that, if you look closely at the cell, you can vaguely see the nucleus, a few ribosomes, and a lysosome.


Cell Parts Flash Cards Actin -Found in both Animal and Plant Cells -Forms microfilaments when linked together -Helps with cell structure

Cell Wall -Found only in Plant Cells -Stabilizes cell so it has rigid structure

Cell Membrane -Found in both Animal and Plant Cells -Is made out of phospholipids and integral and peripheral protiens -It is selectively permeable, it lets certain things pass in and out -It is formed out of a lipid bilayer Chloroplast -Found in Plant Cells only -Helps turn sunlight into energy through photosynthesis -Contains the green pigment chlorophyl

Chromatin -Found in Animal and Plant Cells -A combination of DNA and proteins -Located in the Nucleus


Chromosomes -Found in Animal and Plant cells -Densely packed Chromatin -Found only when a cell is about to divide

Cilium -Found in Animal Cells and few Plant Cells -Short Hair-like projections used in propulsion of the cell -Formed out of Microtubules

Crista -Found in Animal and Plant Cells -The inner folds of the second membrane of the mitochondria in which the Chemical reactions take place

Cytoplasm -Found in Animal and Plant Cells -The substance between the cell membrane and the nucleus that contains all of the cell's organelles Cytosol -Found in Animal and Plant Cells -The jelly- like substance that all of the organelles are bathed in Cytoskeleton -Found in Animal and Plant Cells -Stabilizes the cell and assists in cell division


Endoplasmic Reticulum -Found in both Animal and Plant Cells -Helps synthesize proteins, regulates calcium levels, breaks down toxins, synthesizes steroids, and transports proteins to the Golgi apparatus Rough ER -Helps synthesize proteins and transports them to the Golgi apparatus -Has ribosomes on it Smooth ER -Regulates calcium levels, breaks down toxins, and synthesizes steroids -Has no ribosomes on it Flagellum -Found in both Animal and Plant Cells -Long, Hairlike, projection that assists in moving the cell Fluid Mosaic Model -Found in Animal and Plant cells -A model that shows the lipid bilayer of the cell membrane Golgi Apparatus -Found in both Animal and Plant Cells -Modifies molecules so that they may be used throughout the cell Integral Protein -Found in both Animal and Plant Cells -Helps carry molecules across the cell membrane during passive transport Peripheral Protein -Found in Animal and Plant cells -Found only on one side of the cell membrane Plastid -Found in only Plant Cells -Store starches, fats, and/or pigments -Can absorb light Ribosome -Found in both Animal and Plant Cells -Synthesize proteins -Composed of RNA and Proteins -Formed within the nucleus of the cell


Nucleus -Found in Animal cells and plant cells -Controls all functions that happen within a cell -Synthesizes ribosomes -Stores all of the cell's DNA Spindle Fiber -Found in Animal and Plant Cells -Bundles of microtubules that are found when the cell is about to divide

Thylakoid -Found in Plant Cells only -A membranous sac that is enclosed within a chloroplast Vacuole -Found in both Animal and Plant Cells -Stores food, enzymes, metabolic waste and other materials

IV. Procedure: 1. Heat up water in accordance with the amount listed on the gelatin box into your circular and rectangular pans until it comes to a rolling boil. 2.Once it boils, put the gelatin powder into the boiling pans. 3.As soon as the gelatin powder put ice water into the pan also in accordance with the amount listed on the gelatin box. 4.Put the gelatin into a refrigerator and let it set for a few hours. 5.After it has set, take the gelatin out of the refrigerator and prepare the the ingredients to create the organelles of the cell. 6.Stick the lollipop into the center of the muffin and push the muffin into the center of the gelatin. 7.Push the all the jelly beans into the according to the correct cell into the gelatin. 8.Fold up the fruit roll-ups and push them into the gelatin and for the plant cell add the water vacuole. 9.Insert the twizzlers into the gelatin and sprinkle sprinkles over the top of the model.


V. Data:


VI. Analyze and Conclude: 1.How realistic was the model of your 3-D model in a representation of the cell? It was fairly realistic, except we had too many ribosomes, there was not smooth endoplasmic reticulum, and the plant cell model did not have an accurately portrayed water vacuole. 2.Draw a Venn diagram comparing and contrasting an animal cell from a plant cell.

3.Create a metaphor/analysis explaining the function of each part of an animal or plant cell. Organelle

Function

Metaphor

Cell Membrane

Lets Certain Molecules in the cell and Keeps others out

It is like the guards to a city, they let certain people in and others they do not

Mitchondria

Converts bonds in food into ATP It is like an ATM where you exchange the credit for money

Cytosol

Jelly- Like substance that holds all of the organelles

Nucleas

Controls all processes that go on It is like the government, it in a cell and forms and forms controls everything that goes on ribosomes in a country

It is like a town, it holds all the buildings


Golgi Bodies

“Package� Materials before they They are like a post office that are transported to other parts of packages objects for them to be the cell shipped

Endoplasmic Reticulum

Transport Materials to the Golgi It is like a highway that Bodies transports things

Ribosomes

Creates Proteins to be used throughout the cell

It is like the mint that makes money to be made throughout the cell

Cytoskelton

Hold allows for the cell to hold its shape

It is like the supports on a building, it allows for it to hold its shape

Lysosomes

Breaks down old organelles, viruses, and bacteria

It is like a dump that breaks down used garbage

Water Vacuole

It stores water in plant cells

It is like a water tower that stores water

Chloroplasts

It turns sunlight into energy

It is like a solar panel that turns sunlight into energy

Cell Wall

An outside wall that protects the It is like a wall that lets certain cell from letting certain things things into the city and keeps enter other things out
