- 1. Multiple ChoiceWhich best describes a difference between a unicellular organism and a multicellular organism?A unicellular organism is a plant and a multicellular organism is a human.A unicellular organism has one purpose- to survive. A multicellular organism has many cells working together to keep the organism alive.A multicellular organism is simple and a unicellular organism is complex.A unicellular organism can only be found in certain biomes but a multicellular organism can be found anywhere on Earth.
- 2. Multiple ChoiceWhich states a difference between an animal and an amoeba?An animal is made up of only one cell and an amoeba is made of many cells.An animal is found on land and an amoeba is found in water.An amoeba is single-celled and an animal is multicellular.An animal is a living organism and an amoeba is a non living organism

- 7. Multiple ChoiceFungi and bacteria are both single-celled organisms. What do they most likely have in common?Both fungi and bacteria are large organisms.Both fungi and bacteria can carry out all life functions in their one cell.Both fungi and bacteria need sunlight and nutrients from the soil to be able to grow.Both fungi and bacteria are highly specialized to do only one job so they must work with other cells to obtain food.

- 9. Multiple ChoiceWhich of the following must get nutrients from a transport system?bacteriaamoebafunginerve cell
- 10. Multiple ChoiceBacteria often live inside the body of a living host, such as a dog. Which bestdescribes how bacteria carry out the processes necessary for survival?Bacteria borrow cells from the host to carry out life processes.Bacteria use their many different cells to carry out life processes.Bacteria are made up of one cell which is responsible for carrying out all life processes.Bacteria use their many different cells as well as cells from the host to carry out life processes.

- 18. Multiple ChoiceWhy 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.
- 19. Multiple ChoiceWhich is the best way to classify grasshoppers?Grasshoppers are multi-celled organisms because they are made up of one cell that carries out all of their life processes.Grasshoppers are single-celled organisms because they are made up of one cell that carries out all of their life processes.Grasshoppers are single-celled organisms because they are made up of many cells that carry out all of their life processes.Grasshoppers are multi-celled organisms because they are made up of many cells that carry out all of their life processes.
