What is the function of the cell membrane?

Back

The cell membrane controls what enters and leaves the cell.

Front

What is the coarse focus on a microscope used for?

Back

The coarse focus is used to make large adjustments to the focus of the microscope.

Front

What type of cells have free-floating DNA?

Back

Prokaryotes have free-floating DNA.

Front

What does it mean that the cell membrane is selectively permeable?

It means that certain things can enter the cell while others cannot.

Front

What are the three main points of the Cell Theory?

Back

1. All living things are composed of cells. 2. Cells are the basic units of structure and function in living things. 3. All cells are produced from other cells.

Front

What is the role of the nucleus in a cell?

Back

The nucleus houses the cell's DNA and controls the cell's activities.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the purpose of the fine focus on a microscope?

Back

The fine focus is used for making small adjustments to the focus of the microscope.

Front

What is the structure of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins.

Front

What is the significance of the fluid mosaic model?

Back

The fluid mosaic model describes the structure of the cell membrane as flexible and composed of various proteins that float in or on the fluid lipid bilayer.
