1 LEVELS OF CELLULAR ORGANIZATION Thursday, March 25th
2 AIM: What are the different levels of cellular organization? THURSDAY, MARCH 25THAIM: What are the different levels of cellular organization?Do NowWhat does multicellular mean?Many CellsWhat do you think is more complicated? Cells or Organs? Why? (2 sentences)Organs are more complicated than cells. An organ has many cells working together in order for it to work.
3 LEVELS OF CELLULAR ORGANIZATION Work together to sort the cards at your table from smallest to biggest (2 minutes)
4 LEVELS OF CELLULAR ORGANIZATION BIGORGAN SYSTEM: Two or more tissues working together to perform a specific function/job for the organismORGANS: Tissues work together to perform a specific activityTISSUES: Similar cells working together to do the same functions/jobs.CELLSSMALL
5 HOW DOES OUR BODY WORK TOGETHER TO CIRCULATE BLOOD? organs work together to makeCIRCULATORY SYSTEMtissues work together to makeThe HEART(Organ)cells work together to makeHEART TISSUESorganelles work together inside…HEARTCELLSOrganelles
