- The cell membrane is important for maintaining homeostasis because it controls what enters and leaves a cell.
- Simple diffusion is diffusion that doesn’t take any energy to force molecules in or out, so it is known as passive transport. It moves with the concentration gradient.
- True statements about simple diffusion: A) It is a form of passive transport. B) Molecules travel with the concentration gradient. D) It is how oxygen and carbon dioxide travel across the membrane.
- For the diagram showing movement with the flow: Place 7 circles on the left side (high concentration) and 3 circles on the right side (low concentration), with an arrow pointing from left to right.
- Endocytosis and exocytosis are forms of active transport.
- A scenario for endocytosis: Amoebas rely on endocytosis; pseudopods stretch out around what they want to engulf, then pull it into a vacuole.
- A scenario for exocytosis: To make a cell wall, a cell needs to export carbohydrates produced inside the cell to the outside.
Parent Tip: Review the logic above to help your child master the concept of cellular transport worksheet.
