Transcript of Cell Analogy and Function Presentation

Cell Analogy and Function By Chloe and Wyatt Cell A basic structural and functional unit of all organisms. Function: Analogy: A cell is like a whole system in the form of a castle that operates to make the castle flow and live. Plasma Membrane Function: A special boundary that helps control what enters and leaves the cell. Analogy: The actual building of the castle, because it is the structure that surrounds everything else. Nucleus Function: distinct central organelle that contains the cells genetic material in the form of DNA. Analogy: The nucleus is like the king of the castle who tells and controls the whole castle. Cytoplasm Function: environment inside a plasma membrane in the form of a semi-fluid material. Analogy: The cytoplasm is like the air inside the castle that is outside of the throne room. Nucleolus Function: the sight of ribosome production. Analogy: The nucleolus is like the king of the castle in the throne room that gives orders to workers and or ribosomes. DNA Function: contains the genetic coding. Analogy: The DNA is like the blueprints for the building structure of the castle. Ribosome Function: organelles that help manufacture proteins. Analogy: The ribosomes are like carpenters, builders, and workers who carry around everything and help like a worker. Mitochondria Function: energy generators which convert fuel particles into usable energy Analogy: Windmills outside the castle could be like mitochondria, because it generates energy, turns it into fuel particles, and gives it electricity. Microtubules Function: Microtubules are fibrous, hollow rods, that function primarily to help support and shape the cell. Analogy: The Microtubules are like the pipes in the building that support the structure, and carry water. Golgi Body Function: flattened stack of membranes that modifies, sorts, and packages proteins into sacs called vesicles. Analogy: Rough Endoplasmic Reticulum Function: The area of ER where ribosomes are attached. The endoplasmic reticulum is to transport ribosomes to the golgi apparatus. Analogy: Both rough and soft endoplasmic reticulum are like hallways that transport cellular materials. Structure: A microtubule is a polymer of globular subunits. Structure: region within nucleus where ribosomes are made, stained slightly darker. Structure: Structure: Two layers of phospholipids, one hydrophilic, one hydrophobic, with embedded transport proteins. Smooth Endoplasmic Reticulum Structure: The general structure of the endoplasmic reticulum is a membranous network of cisternae. Function: The area of ER where ribosomes aren't attached. Analogy: Both rough and soft endoplasmic reticulum are like hallways that transport cellular materials. Structure: The general structure of the endoplasmic reticulum is a membranous network of cisternae. Lysosomes Structure: The outside is made of a lipid bilayer and has a glycosolated membrane to transport proteins. Function: The function is to digest things and to hold enzymes. Analogy: The lysosome is like a maid who cleans up things and breaks down cell materials. Centrioles Structure: Groups of microtubules. Function: Centrioles organize the assembly of microtubules during cell division. Analogy: Centrioles could be like the workers, or supervisors that organize things within the castle. Structure: Membranes filled with cristae and matrix. Structure: Double Helix structure Nuclear Membrane Structure: The nuclear membrane is a double lipid bilayer that surrounds the genetic material in the nucleus. Function: The nuclear membrane does protect the nucleus but more importantly it controls what comes in and out of the nucleus. Analogy: The nuclear membrane is like the gates to the castle that controls what comes in the castle and what goes out. Structure: The cell is a complex building block of life that has many organelles to help it function.
The animal cell is in a spherical shape.
The plant cell is in a rectangular shape. The golgi body is like a warehouse that stores certain packages like how the golgi body stores and packages proteins. Structure: A double membrane with 2 phospholipid layers to allow things to pass through. Structure: Cellular fluid called cytosol, and organelles. Structure: Two subunits of RNA and proteins. cisternae, which are flattened stacks of membrane usually found in a series of five to eight. E.R. is composed of three different types of structure. These are cisternae, vesicles and tubeless. The Animal Cell Endoplasmic Reticulum Hydrophilic- Water Loving
The yellow spheres are the hydrophilic regions Hydrophobic- Water Fear
The green strands are the hydrophobic regions The mitochondria converts oxygen and nutrients into ATP (adenosine triphosphate). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. THE END
