2LEARNING OBJECTIVES4. I know that cells are the basic unit of all life and I can describe the functions that cells/life forms must carry out. 5. I know that single-celled organisms have parts to help them carry out all of life’s functions. 7. I know that plant and animal cells have parts in common and parts that are different in order to carry out life functions. 8. I can use a diagram or model to explain the difference between plant and animal cells.
4CELLSCells are the smallest unit of LIFE! They are the building blocks of LIVING things.No matter if an organism has ONE cell or many, they share the same basic parts.
5Inside the cell, are structures (parts) called ORGANELLES (means “little organs”) Each organelle has a certain function (job) to do.
6***We are only learning about the basic organelles; there are others which you might hear about in the reading and activities but you will not be tested on those.
7Fill in the Table as we go Cell part is given,Write in any functionsNote the pictures that go with each part
8CYTOPLASM CYTOPLASM GEL- like material inside the cell. Mostly water CELL PARTJOB/FUNCTIONPictureCYTOPLASMGEL- like material inside the cell.Mostly waterThe other organelles “float” in cytoplasm“Cyto” means cell“-plasm” means jelly
9CELL MEMBRANE “GATEKEEPER”—controls what goes in and out of the cell. CELL PARTJOB/FUNCTIONPictureCELLMEMBRANE“GATEKEEPER”—controls what goes in and out of the cell.
10NUCLEUS NUCLEUS Directs all cell ACTIVITIES CELL PARTJOB/FUNCTIONPictureNUCLEUS Directs all cell ACTIVITIESContains DNA (instructions for cell)Largest organelle“boss” of other organelles
11MITOCHONDRIA Releases ENERGY in the cell; “POWERHOUSE” CELL PARTJOB/FUNCTIONPictureMITOCHONDRIA Releases ENERGY in the cell; “POWERHOUSE”Performs cellular respiration
12CHLOROPLAST Found in PLANT CELLS only!!! CELL PARTJOB/FUNCTIONPictureCHLOROPLASTFound in PLANT CELLS only!!!Converts SOLAR (SUN) ENERGY into cell energy.
13CELL WALL CELL WALL Found in plants ONLY! CELL PARTJOB/FUNCTIONPictureCELL WALLFound in plants ONLY!OUTER SUPPORT structure; made of cellulose.
14VACUOLESCELL PARTJOB/FUNCTIONPictureVACUOLESStores WATER, food, and waste products. Usually larger in PLANTS.
15What are the two parts plant cells have that animal cells do not have? Cell WallsChloroplastsClip
19Cells are Systems!Individual cells are SYSTEMS because they have PARTS that work together to do a certain JOB.
20Cells are Systems! What are some INPUTS? Food, water, oxygen, light (plant cells)What are some OUTPUTS? waste, CO2, water, chemical/thermal energyOpen or Closed? Why?Open because MATTER (molecules) can go IN/OUT of the cell membrane
