Levels of Organization 7.L.1.3

Infographic - Hierarchy of LifeThis infographic represents the information we covered in class regarding how multicellular organisms are organized to survive. Levels of Organization Watch the short video on the levels of organization then complete a summary. Read the passage and then determine the vocabulary word needed to complete the sentences. A cellis the most basic or simplest level of organization of multicellular organisms. A group of similar cells working together to perform a function is called a tissue. Groups of dissimilar tissues that function together to complete a job make up an organ. Multiple organs that work together to perform a function make up an organ system. A group of systems that work together to sustain life makes up an organism. cell the basic unit of life tissue a group of similar cells that work together organ a group of dissimilar tissues working together organ system a group of organs that work together organism a group of systems that work together to sustain life How many levels of organization are there in living organisms? 1 3 5 7 The liver is composed of cells called "hepatocytes." Many hepatocytes together in the liver form cells tissue organ system organis The stomach is a collection of tissue that contracts to help digest food. The stomach is considered to be a(n) cell tissue organ organ system In the human heart, there are organs that pump blood through blood vessels. The combination of the heart and blood vessels are classified as a tissue an organ an organ system an organism Which of the following examples best shows the levels of organization from most complex to least complex? human --> lung tissue--> lung cell--> lungs--> respiratory system human--> respiratory system--> lungs--> lung tissue--> lung cell lung cell--> lung tissue --> lungs --> respiratory system--> human Which of the following examples best shows the levels of organization from least complex to most complex? human--> lung tissue--> lung cell--> lungs--> respiratory system human --> respiratory system--> lungs--> lung tissue--> lung cell lung cell--> lung tissue--> lungs--> respiratory system--> human The basic unit of structure and function in life is cells tissues organs organisms The image below is a level of organization diagram.
