A cell is a cell but how can you tell?. Robert Hooke-1665. Examined many living and non-living things under the microscope. Living things seem to be made of “compartments” He called these compartments, cells. Cork is the outer bark of an evergreen oak. Cells.

Robert Hooke-1665 • Examined many living and non-living things under the microscope. • Living things seem to be made of “compartments” • He called these compartments, cells Cork is the outer bark of an evergreen oak
Cells • Are made up by organelles or parts that have specific jobs.
More info on size of cells the Ostrich egg is the largest cell on Earth It is about the size of a football mycoplasma bacterium is the smallest cell in the world. It is only ten micrometers
Cell Membrane • the thin layer of protein and fat that surrounds the cell. Jello Model: Plastic ziploc bag
Cytoplasm • the jellylike material outside the cell nucleus in which the organelles are located. Jello Model: gelatin
Golgi Body • a flattened, layered, sac-like organelle that looks like a stack of pancakes • packages proteins and carbohydrates into vesicles for "export" from the cell. Jello Model: Folded hard ribbon candy
Lysosomes • round organelles surrounded by a membrane and containing digestive enzymes. • digestion of cell nutrients takes place here Jello Model” M & M Candy
Mitochondria • spherical to rod-shaped organelles *the inner membrane is infolded many times • Gives energy to the cell Jello Model: raisins
Nucleus • spherical body containing many organelles • controls many of the functions of the cell and contains DNA (in chromosomes). Jello Model: A plum
Ribosomes • small organelles where proteins are made. Jello Model: Candy sprinkles
Endoplasmic ReticulumIt functions as a packaging system. It creates a network of membranes found through the whole cell • Smooth It acts as a storage organelle. For example: It is important in the creation and storage of steroids. Jello Model: Gummy worms • Rough They are very important in the synthesis and packaging of proteins. Some of those proteins might be used in the cell and some are sent out. Jello Model: Sour gummy worms-rough
Vacuoles • Vacuoles are essentially enclosed compartments which are filled with water containing important stuff for the cell dissolved in it
What do plant cells have that animal cells do not?” • Cell Wall • Chloroplasts
A rigid structure that protects the plant Provides structure and shape Cell Wall-only in plants
Chloroplasts • Capture sun light and chemically change it to sugar. • Chloroplasts are the food producers of the cell.
