2 LEARNING 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.
4 CELLSCells 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.
5 Inside 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.
7 Fill in the Table as we go Cell part is given,Write in any functionsNote the pictures that go with each part
8 CYTOPLASM 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
9 CELL MEMBRANE “GATEKEEPER”—controls what goes in and out of the cell. CELL PARTJOB/FUNCTIONPictureCELLMEMBRANE“GATEKEEPER”—controls what goes in and out of the cell.
10 NUCLEUS NUCLEUS Directs all cell ACTIVITIES CELL PARTJOB/FUNCTIONPictureNUCLEUS Directs all cell ACTIVITIESContains DNA (instructions for cell)Largest organelle“boss” of other organelles
11 MITOCHONDRIA Releases ENERGY in the cell; “POWERHOUSE” CELL PARTJOB/FUNCTIONPictureMITOCHONDRIA Releases ENERGY in the cell; “POWERHOUSE”Performs cellular respiration
12 CHLOROPLAST Found in PLANT CELLS only!!! CELL PARTJOB/FUNCTIONPictureCHLOROPLASTFound in PLANT CELLS only!!!Converts SOLAR (SUN) ENERGY into cell energy.
13 CELL WALL CELL WALL Found in plants ONLY! CELL PARTJOB/FUNCTIONPictureCELL WALLFound in plants ONLY!OUTER SUPPORT structure; made of cellulose.
14 VACUOLESCELL PARTJOB/FUNCTIONPictureVACUOLESStores WATER, food, and waste products. Usually larger in PLANTS.
15 What are the two parts plant cells have that animal cells do not have? Cell WallsChloroplastsClip
19 Cells are Systems!Individual cells are SYSTEMS because they have PARTS that work together to do a certain JOB.
20 Cells 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
