Biological Organization Models
At the science museum, Jamal and Amara are exploring how living things are organized. Use the exhibit model and clues to solve each task. Think from the smallest living level to the whole organism.
Build a Living Thing
The museum model shows a common sequence of organization in an animal. Each level is made from parts at the level before it, and organs or systems can interact.
1.A visitor sees a model of a single living unit that can carry out life processes. Which level is it?
- Tissue
- Cell
- Organ
- Organ system
2.Put these levels in order from smallest to largest: organism, tissue, cell, organ system, organ.
3.At the exhibit, Amara reads: “A group of similar cells working together for a function.” Name this level of organization.
4.Which set contains only organs? Select the best answer.
- Heart, stomach, brain
- Blood, muscle tissue, skin cells
- Circulatory system, heart, tissue
- Cell, tissue, organism
5.Fill in the missing levels: heart muscle cells → muscle tissue → → circulatory system → human.
6.Jamal says, “The heart is a tissue because it contains muscle tissue.” Is his claim correct? Explain briefly.
7.Match each biological level to its example.
- Cell
- Tissue
- Organ
- Organ system
- Nervous tissue
- Neuron
- Brain
- Nervous system
8.The museum's model shows that the heart pumps blood through blood vessels. Predict one way a damaged heart could affect the circulatory system and the whole organism.
9.True or false: Every organ system works completely independently of every other organ system.
TrueFalse
10.Choose one organ system. Describe a correct path from one type of cell to the whole organism, naming a tissue, an organ, and the organ system along the way.
11.Write a caption for the exhibit model explaining why biological organization is useful to living things.
