Which of the following best describes the relationship between cells and living things in general?

• The larger the living thing, the larger its cells.

• All living things are made up of one or more cells.

• The number of cells in all living things is the same.

• There is one kind of cell, which all living things are made of.

Which of the following statements is TRUE about cells?

• Cells are made up of smaller living things, called organelles.

• For something to be alive, it must be made of many cells.

• Cells are the smallest unit that can be considered alive.

• Only groups of cells that function together are actually alive.

What sort of evidence must be gathered to support the idea that all living things are composed of cells?

• Comparisons should be made between non-living things and living things to determine any similarities in their structure.

• Samples of many kinds of living things should be examined under a microscope to identify the presence of cells.

• The functions of cells from many different living things should be monitored to see if they are identical.

• Non-living things should be examined to verify that the smaller parts of which they are composed are not cells.

Students conducted an investigation to provide evidence to support the idea that trees were made up of different kinds of cells. Which of the following provides evidence which would support this idea?

• Samples taken from different parts of any tree all contained cells.

• Cells from different parts of a single tree had varying structures and functions.

• Cells collected from one tree were different from cells collected from another tree.

• One cell collected from a single tree was made up of several different parts.

Students examined the smaller structures of living things and non-living things. Which of the following observations provides evidence that the smaller parts of living things, and not the non-living things, are cells? Smaller parts of living things–

• are tightly packed together with almost no space between them.

• carry out functions that sustain life such as respiration.

• are uniform in size and structure.

• cannot be seen with the unaided eye but requires a microscope.
