Organs, organ systems, organisms, atoms, molecules, cells, tissues
Structures in the human body work together to perform specific functions. The diagram below shows the organization of structures found in the human body.
A picture of which of the following structures belongs in the box above?
Cell
Organ
Organelle
Tissue
Eugene drew the following diagram to describe the levels of structural organization of an animal’s body. At the top of the pyramid he put the animal’s body. The level of organization that is least specialized will be at the bottom.
Which of the following should Eugene list at the bottom of his diagram?
Organ
Tissue
Cell
Organ system
Which term best fits the level of organization pictured in the diagram?
Organ
Tissue
Single cell
Organ system
The diagram shows parts of the human body. These parts work together to help you digest the food you eat.
Which term best describes the entire group of parts that are labeled?
Organ
Tissue
Cell
Organ system
In a human body, which of the following represents the highest level of structural organization?
Lung tissue
The lungs
The respiratory system
An atom in the lung
Which of these statements describes an organ system?
Many cells working together to perform a function
Many organs working together to perform a function
Many cells working separately to perform different functions
Many organs working separately to perform different functions
Cells exchange materials with their environment. What is the main reason for this?
To replace damaged and dying cells
To keep the cell membrane functioning
To release energy into their environment
To get rid of wastes and take in nutrients
Which of the following is something that all cells must be able to do to survive?
A. Divide
B. Use oxygen
C. Remove wastes
D. Make their own food
A, B and C

Only D
B and D
The survival of cells depends on maintaining homeostasis.
What will happen to a cell if homeostasis is not maintained?
The cell will immediately divide.
Many chemical reactions in the cell will slow down or even stop.
The cell will eliminate wastes more efficiently.
Cell processes will continue unchanged.
Which of the following is something that all living organisms have in common?
They all contain at least one cell.
They all need a source of oxygen.
They all use other organisms for food.
They all find mates to reproduce.
Which of the following is not part of the cell theory?
Cells come from other cells.
All living things are made of cells.
Cells can be seen through a microscope.
Cells are the units of structure and function in living things.
Which characteristic is shared by all cells?
They need energy.
They reproduce sexually.
They make their own food.
They move from place to place.
Homeostasis is necessary for a cell to survive.
What is the definition of homeostasis?
The elimination of wastes
The process by which energy from the sun is used to make food
The maintenance of a stable internal environment
The division of cells to form new cells
What is one way stress can affect homeostasis?
It disrupts ability to fight disease
It increases water balance.
It maintains constant internal temperature.
It decreases the frequency of headaches.
The cell theory applies to all organisms, including the five shown above.
Which of the following statements describes how these organisms are an example of the cell theory?
The cells of the organisms undergo photosynthesis.
The organisms are made of one or more cells.
The cells of the organisms are identical to each other.
The organisms have cells that lack a nucleus.
What is homeostasis?
The body's tendency to keep an internal balance
Cell wall
Peninsula
Staying hydrated
Plant cells are different from animal cells. The diagram below identifies four different structures in a plant cell.
Compared to the structures in an animal cell, which of the following structures is found only in a plant cell? .
