Grade 5 Cell Structure and Function
What organelles in the cell are responsible for releasing energy for the cell?
  1. nucleus
  2. cytoplasm
  3. mitochondria
  4. alveoli
Grade 5 Cell Structure and Function
The cell membrane is the
  1. jelly-like substance that fills plant and animal cells.
  2. tiny unit of a living thing.
  3. thin layer that allows some material to pass in and out of plant and animal cells.
  4. stiff outer layer of a plant cell.
Grade 5 Cell Structure and Function
The part of the plant cell known as the "brain" of the cell is the
  1. cell wall.
  2. nucleus.
  3. cytoplasm.
Grade 5 Food Chains and Webs
The images below show a partial food chain.
Pictograph - Grass→Pictograph - Mice→Pictograph - Snake
Which organism would most likely come after the snake in the food chain?
  1. Pictograph - Larva
  2. Pictograph - Eagle
  3. Pictograph - Mice
Grade 5 Adaptations and Behavior
The main purpose of an adaptation is to
  1. help an animal survive.
  2. get food.
  3. provide a habitat.
  4. change the animal's appearance.
Grade 5 Cell Structure and Function
A cell is the
  1. storage space.
  2. tiny unit of a living thing.
  3. cell energy processor.
  4. stiff outer layer of a plant cell.
Grade 5 Food Chains and Webs
Imagine that pollution caused all the plants in an aquatic food chain to die. Would this affect the population of the largest fish?
  1. Yes, because the largest fish need to eat plants to supplement their diet.
  2. Yes, because all the food energy in the chain begins with the plants.
  3. No, because the largest fish are big enough to survive a change in the ecosystem.
  4. No, because only the smallest fish depend on the plants for survival.
Grade 5 Respiration, Digestion, and Excretion
Which system of the body allows you to breathe?
  1. circulatory
  2. respiratory
  3. digestive

Grade 5 Cell Structure and Function
Which plant cell part gives the plant support and is not part of animal cells?
  1. chloroplast
  2. cytoplasm
  3. cell membrane
  4. cell wall
Grade 5 Cell Structure and Function
How can a student distinguish a plant cell from an animal cell?
  1. If the cell has a cell wall, it must be from a plant.
  2. If the cell has cytoplasm, it must be from a plant.
  3. If the cell has a nucleus, it must be from an animal.
  4. If the cell has a cell membrane, it must be from an animal.
Grade 5 Respiration, Digestion, and Excretion
Which system brings oxygen into the lungs?
  1. digestive system
  2. respiratory system
