Life Science, Multicellular Organisms Review

A scientist found a new life form. It does not make its own food, it has a backbone, and it lives in water. How should the scientist classify this new life form?

• bacteria
• fungus
• animal
• plant

Multicellular organization from most complex to most basic

• Organ system --> Organ --> Tissue --> Cell 
• Cell --> Tissue --> Organ --> Organ system

Sue and Allie read about different kinds of organisms. They read about an organism with a respiratory system, digestive system, skeletal system, and muscular system. Which can Sue and Allie most likely conclude about this organism?

• The organism is unicellular.

• This organism is microscopic.

• The organism is multicellular.

• The organism does not have any cells.

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.

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.

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.

Which best describes a multi-celled organism?

• basic

• simple

• uniform

• complex

Which is a multi-cellular organism?

• algae

• cricket

• bacteria

Which organisms are capable of surviving as a single cell?

• bacteria

• humans

• plants
