Learning Target: Students will create a model of a cell, labeling each part, and designing a key with the definition/function of each part.
Your assignment is to create a fantastic, colorful, and accurate model of a cell. It may be a poster, 3D model, edible, or any creative way you want that exhibits knowledge of cytological anatomy (the parts of a cell and their jobs). The cell may be either a plant or an animal. If you decide to make an edible cell, it will not be shared at school. You may work with partners if you receive teacher permission.
This website gives you great ideas on how to create a cell model:
This powerpoint has images of fantastic projects:
Animal cells must have the following organelles:
5. cell membrane
Plant cells must have the following organelles:
5. cell membrane
7. cell wall
Don’t forget to include a key with your creation. Define or explain the function of each cell part on your key. Your grade is based on cell accuracy, completeness, creativity, neatness, and effort.
Cells Vocabulary List & Definitions
|Jelly-like substance that makes up the matrix of the cell body.|
|mitochondrion||Shaped like a bean, this cell organelle helps take food and manufacture energy from it.|
|nucleolus||A structure inside the nucleus where RNA is transcribed.|
|nucleus||the main brain of the cell that contains most of the cell's DNA.|
|organ||a body structure that works to perform a specialized function. Examples include the lung or heart.|
|tissue||a large series of cells that work together to form a specific function.|
|vacuole||storage areas of the cell known for storing mostly water and/or food.|
|cell membrane||The enclosure of the cell that provides the body for all the organelles.|
|cell wall||Mostly made of cellulose, this is the tough and rigid outer layer of plant cells.|
|chlorophyll||the green (in color) pigment found in chloroplasts where photosynthesis takes place.|
|chloroplast||an egg shaped body that appears green from all the chlorophyll they contain. This organelle is where photosynthesis takes place.|
Thin, intertwined pieces of DNA found in the cell's nucleus.
cell membrane - the thin layer of protein and fat that surrounds the cell.
cytoplasm - the jellylike material outside the cell nucleus in which the organelles are located.
cytoskeleton- a microscopic network of protein filaments and tubules in the cytoplasm.
Golgi body - (also called the Golgi apparatus or Golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. It is actually a stack of vesicles bound to the membrane.
lysosome - (also called cell vesicles) round organelles surrounded by a membrane and containing digestive enzymes.
mitochondrion - spherical to rod-shaped organelles with a double membrane. The inner membrane is infolded many times, forming a series of projections (called cristae). They provide energy to the cells.
nucleolus - an organelle within the nucleus - it is where ribosomal RNA is produced. Some cells have more than one nucleolus.
nucleus - spherical body containing many organelles, including the nucleolus. It is enclosed in a double membrane and communicates with the surrounding cytosol.
ribosome - small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.
rough endoplasmic reticulum - (rough ER) a vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). Rough ER is covered with ribosomes that give it a rough appearance.
smooth endoplasmic reticulum - (smooth ER) a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). The space within the ER is called the ER lumen. It appears smooth by electron microscopy.
vacuole - fluid-filled, membrane-surrounded cavities inside the cell
