Total questions: 20
Worksheet time: 11mins
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

Located in the cytoplasm
Bacteria-sized organelle
Converts energy for cell use
Contains a folded inner membrane
What types of organisms have cells with very large vacuoles?
animals
bacteria
fungi
plants
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
You make a model of a cell in a large, rectangular, clear, plastic container filled with the following: gelatin, green M&Ms™, red licorice, several beans, one large inflated balloon, candy sprinkles, and an avocado seed.
What kind of cell is represented by the above model?
plant
animal
bacteria
fungi

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.
A school’s cafeteria kitchen has a large, walk-in refrigerator where food is stored for lunch later in the week. Which cell organelle has a function that is similar to the refrigerator?
Vacuole
Nucleus
Chloroplast
Mitochondria
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
Which of the following statements accurately represents the differences in plant and animal cells?
Only plant cells have a cell wall, chloroplasts, and a large vacuole.
Only animal cells have a cell wall, chloroplasts, and a large vacuole.
Only plant cells have a cell membrane, mitochondria, and cytoplasm.
Only animal cells have a cell membrane, mitochondria, and cytoplasm.
The primary function of a chloroplast is to —
convert food into energy a cell can use
control the functions of a cell and control genetic traits
convert radiant energy into chemical energy through photosynthesis
store water and nutrients
Which of the following do all living organisms have in common?
Cells held up by cell walls
The method to get water and food into their cells
Cells made from pre-existing cells
Special cells that can do many different things
A student observing a sample of cheek cells noticed that all of the cells were identical. Which statement below explains why these cells are identical?
They all come from the same location in the body.
All cells come from other cells through division.
They do not have a cell wall
They have a chloroplast
As students left class, they were asked to write a statement about the properties that all cells share. A sample of student statements is recorded above. Which students wrote correct statements about the properties that all cells share?
Students A and D
Students B and C
Students B and D
Students A and C
According to cell theory, what do each of the following organisms have in common?
They can all reproduce by spontaneous generation
Each organism is able to photosynthesize.
Cells are the basic unit of structure for each organism
They are all made up of the same kinds of atoms.
Your body has a layer of skin that protects it from its environment. This layer of skin is made up of many individual skin cells. Explain where all the cells came from and how two individual cells share the same traits.
Cells come from other cells and share the same traits because of Mitosis. (Cell divosion)
Cells free form but have the same DNA
You are born with all of the cells you will ever have.
