Living organisms are made up of cells. Cells are organized at different levels to form very complex living organisms like your body. Each level has a specific role or job to perform. Which of the following lists these levels in the correct order of organization from the simplest to the most complex?
Cells, tissues, organs, organ systems, organisms
Organisms, organ systems, organs, tissues, cells
Tissues, cells, organs, organisms, organ systems
Organs, organ systems, organisms, cells, tissues
The food that you eat travels from your mouth, down your esophagus, into your stomach, and through your small and large intestines before your body rids itself of solid waste. As the food passes through your body, it is digested, and you get important nutrients from the food.
Which of the following is the correct term used to describe a group of body parts working together to perform a specific function?
An organism
A tissue
An organ system
An organ
What types of organisms have cells with very large vacuoles?
Animals
Bacteria
Fungi
Plants
Which phrase best describes the function of mitochondria?
Located in the cytoplasm
Bacteria-sized organelle
Converts energy for cell use
Contains a folded inner membrane
Through which cell structure does waste exit the cell?
Cell membrane
Chloroplast
Vacuole
Nucleus
Which cell organelle stores DNA?
Cell wall
Cell membrane
Vacuole
Nucleus
Students observed cells under the microscope. They observed that the cells had a cell wall, cell membrane, nucleus, and many chloroplasts.
Which observation helps students identify the type of cell observed?
The presence of a nucleus means the cells are from a plant.
The presence of a cell membrane means that the cells are from an animal.
The presence of chloroplasts means that the cells are from a plant.
The presence of a cell wall means that the cells are from an animal.
The fluid surrounding the organelles of a cell is the —
chloroplast
cytoplasm
mitochondria
cell membrane
The purpose of the cell wall is to —
regulate what goes into and out of a cell
control the functions of a cell
convert energy from food into energy for a cell
provide structure for a cell

As the season turns from fall to winter, what is the most likely response that a wolf’s body has to the changing season?
The wolf stores more fat to maintain body heat and provide nutrition when there may be less prey.
The wolf produces less fur and sheds more fur to help the wolf move quickly to find shelter in the cold.
The wolf produces more melanin causing the fur to be darker so that the pack can see other individuals easily.
The wolf runs more and eats less food to maintain less body mass to keep warm throughout the winter.
