1LEVELS OF CELLULAR ORGANIZATION Thursday, March 25th
2AIM: 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.
3LEVELS OF CELLULAR ORGANIZATION Work together to sort the cards at your table from smallest to biggest (2 minutes)
4LEVELS 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
5HOW 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
6Why isn’t there cellular organization in unicellular organisms? CHALLENGE QUESTIONWhy isn’t there cellular organization in unicellular organisms?
7GROUP CHALLENGE GAME! Who remembers the rules? RULES: Work as a team to answer the questionsKeep your answers secret until time is calledNo talking while your answers are raisedNo cheering or booingTeam with the most points wins!ARE YOU READY?
