Below are sample questions representative of the exercises included on this worksheet and related 6.67 Cell Theory and Types of Cells skill assessments:

Problem 1Difficulty: Mastery
Two classroom models are compared. Model A uses one giant cell to represent a dog. Model B shows many different cell types arranged into tissues and organs. Which model better represents cell theory, and why?
AModel A, because all living things are single cells if they are animals.
BModel A, because tissues are not made of cells.
CModel B, because dogs are nonliving collections of organs.
DModel B, because a dog is a multicellular organism made of many specialized cells.
Solution & Explanation:Model B fits cell theory because a dog is built from many specialized cells organized into tissues and organs.
Problem 2Difficulty: Mastery
Which combination of observations would most likely come from a living sample?
AIt is made of repeating crystal edges with no cell boundaries.
BIt is completely hollow and contains no structures at all.
CIt is made of one or more cells with membranes and cytoplasm.
DIt is made only of metal wires and plastic sheets.
Solution & Explanation:Living samples are made of cells, and cells have basic structures such as membranes and cytoplasm.
Problem 3Difficulty: Mastery
A comparison image shows one bacterium and one piece of fish tissue. Which explanation is best?
AThe bacterium must be nonliving because it is only one cell.
BThe bacterium is a complete unicellular organism, while the fish tissue is only one part of a multicellular organism.
CThe fish tissue is unicellular because the image shows only one tissue sample.
DBoth examples represent the same number of cells and the same level of organization.
Solution & Explanation:A bacterium can be a whole organism by itself, while fish tissue is made of many cells within a larger organism.
