Unit 2 Test Part 1: Cells and Cells Processes: Life Science

Explain the function of the cell membrane.

• It protects and supports the cell.

• It performs different functions in each cell.

• It controls what enters and leaves the cell.

• It forms a hard outer covering for the cell.

Analyze the illustration and determine which cell process is taking place in the FIRST picture.

• Endocytosis

• Active Transport

• Exocytosis

• Passive Transport

Compare and contrast the cell wall and cell membrane.

• While both structures are found on the OUTSIDE of the cell, only the CELL MEMBRANE controls what substances enter and leave the cell.

• While both structures are found on the OUTSIDE of the cell, only the CELL WALL controls what enters and leaves the cell.

• While both structures are found on the INSIDE of the cell, only the CELL MEMBRANE controls what substances enter and leave the cell.

• While both structures are found on the INSIDE of the cell, only the CELL WALL controls what enters and leaves the cell.

Osmosis and diffusion are related in that _________________.

• both are methods to stop movement of molecules across a cell membrane.

• osmosis is the movement of water across the cell membrane by diffusion.

• both involve the movement of large molecules across the cell membrane.

• both processes only work in red blood cells.

The diagram shows a cell taking in a substance that is present in a higher concentration inside the cell than outside the cell. Identify the process that the diagram represents?

• osmosis

• engulfing

• passive transport

• active transport

Smaller molecules, such as oxygen and carbon dioxide, cross the cell membrane through what process?

• osmosis

• active transport

• special gas transport proteins

• diffusion
