Fish are multi-celled organisms with specialized cells. What would most likely happen if their specialized cells did not function properly?
The fish would decrease in size.
The fish would increase in size.
The fish would die.
Which of the following states a difference between single-celled organisms and multi-celled organisms?
Single-celled organisms are dead while multi-celled organisms are alive.
Single-celled organisms do not have organs while multi-celled organisms have organs.
Multi-celled organisms are made up of cells performing the same function while single-celled organisms are not.
Which characteristic best describes both amoebas and bacteria?
abiotic

single-celled
Why do humans require many different types of cells to survive?
Human cells are identical and work together to perform the same function.
Human cells are specialized and work together to perform the same function.
Human cells are identical and work independently to perform different functions.
Human cells are specialized and work independently to perform different functions.
Which best describes a multi-celled organism?
basic
simple
uniform
complex
Which statement would most likely be found in an article about multicelled organisms like plants?
Plants have a simple structure.
Plants contain only one cell that performs all functions.
Plants do not need to eat, remove waste, or reproduce.
Plants contain many specialized cells that perform different functions.
How are single-celled organisms and multi-celled organisms similar?
Both need food for energy and growth.
Both have a skeletal system for support.
Both require the interaction of many cells to survive.
Both are able to carry out all life functions in only one cell.
How are multi-celled and single-celled organisms different?
Multi-celled organisms need energy to survive, while single-celled organisms need no energy to survive.
Single-celled organisms can be seen without using a microscope, while multi-celled organisms are microscopic.
Multi-celled organisms have large numbers of specialized cells to perform a variety of life functions, while single-celled organisms complete life functions with one cell.
Single-celled organisms have large numbers of identical cells that all perform the same function, while multi-celled organisms have cells that are all different and perform different life functions.
In which way are multicellular organisms similar?
All of their cells transport food.
All of their cells have the same job.
All have cells that work together to keep the organism alive.
All have one cell that meets all the basic needs of the organism.
Which best describes all unicellular organisms?
Every cell is round
Every cell can make food.
Every cell can move on its own.
Every cell performs all life functions.
Bacteria (prokaryotes) are unlike all other organisms in that their cells
do not have a nucleus
have organelles
have cell walls
