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

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

all living cells have an important function

new cells come from pre-existing cells

all living organisms are made of one or more cells

cells are the basic unit of structure and function

Which of the following statements is NOT a part of cell theory?

All living things are made up of atoms.

All living things are made up of cells.

Cells are the basic building blocks of life.

All cells come from pre-existing cells created through the process of cell division.

A scientist places a single cell in a petri dish. The scientist observes the dish over the next two days and counts the number of cells, collecting the data in Table 1. The scientist's experiment was most likely about which part of the cell theory?

The cells grown in a petri dish all come from preexisting cells.

The number of cells grown in a petri dish will double every 12 hours.

The cells grown in a petri dish will only survive for 48 hours.

Single-celled organisms can grow in a petri dish.

A scientist is exploring the microscopic world of organisms and sees a structure inside a single-celled organism they can't clearly observe. Under 400x magnification, with a compound light microscope, the structure looks like a circle with small wavy lines inside of it. At this magnification, the unknown structure takes up the field of view. This microscope has four objective lenses with the highest magnification being 1,000x. What is the best solution for this scientist to observe this object more clearly?

The scientist should change the magnification to 1,000x, which will increase the size of the image so it can be viewed more clearly.

The scientist should change the objective lens from 40x to 4x, which will make the image bigger.

The scientist should increase the magnification to 1,000x, which would keep the image the same size.

The scientist should keep the magnification the same but change the tube length of the microscope.

Which characteristic of a scientific theory makes it different from a claim?

It is an explanation of observations.

It is a good guess about a phenomenon.

What aspect of cell theory is shown in this image?

Cells are the basic unit of structure and function in living things.

Cells arise from existing cells.

Only plants are made up out of cells.

Only parts of plants are made up of cells.
