LET’S TRY ONE
A cell membrane controls movement of substances into and out of a cell. Which structure regulates this exchange?
Cell membrane
The supplied description assigns exchange control to the cell membrane.
Learning steps & teaching tips
Use supplied cell-structure descriptions to identify functions without assuming all cells contain every structure.
- Read the function rather than relying on a drawing's position.
- Distinguish a cell boundary, information store and energy-related structures.
- Keep statements limited to the cell type described.
Try it together
Make structure/function cards for a model plant cell. Sort the cards, then note that the model does not describe every kind of cell.
Match the function stated in the question to the described structure.
