Cells Organism: An individual living thing. It can be made up of one cell (unicellular) or up to billions of cells (multicellular). Cell: “Little room” that run on energy from the sun (sugars), they are alive because they take in nutrients, water and get rid of waste. They reproduce too.
Cell Cells have structures (organelles) inside that help them carry out the characteristics of life: Nucleus: “Brain/Library of the cell”, it has all of the directions to control the activities of the cell and reproduces. Mitochondria: “Powerhouse of the cell” it produces energy from sugars Endoplasmic Reticulum: Passageways through the cytoplasm of the cell to carry nutrients and wastes through the cell.
Cell Ribosome: Protein factories of the cell (cell needs proteins to grow and repair cell parts) Vacuoles: Storage tanks for the food, water or waste in the cell. Plant cell vacuoles are large, animal cells are small. Lysosomes: “Clean up crew” for wastes in the cell. In animal cells. Chloroplast: In plants only. It captures the sun’s energy and makes sugars through photosynthesis. Cell wall: In plant cells only. It is the stiff outer layer that protects and supports the cell. Cell Membrane: Outer covering of the cell that protects it and allows certain items to enter and exit.
Cell Drawing Split your paper into 2 sections, 1 will be an animal cell, the other will be a plant cell. Draw and color each and include the following cell structures and a definition of what they do for the cell: NucleusMitochondria Endoplasmic reticulumRibosome VacuoleLysosome Cell membraneCell wall Chloroplast **Use your green panda book on p. 73/74 to help you!**
Cell Poster Rubric Draw and color a PLANT CELL and an ANIMAL CELL and include the following cell structures/organelles and a definition of what they do for the cell: NucleusMitochondria Endoplasmic reticulumRibosome VacuoleLysosome Cell membraneCell wall Chloroplast 7 organelles labeled and with definitions 14 pts Colored, neat with a title6 pts
Cells: Elodea and Cheek Cells Today we are going to look at: A plant cell: Elodea An animal cell: Cheek cell For both cells you will be making a wet mount slide using a coverslip: http://www.biology.ualberta.ca/facilities/multimedia/upl oads/procedures/slip.html
