Biology Passive and Active Transport

Daniel, Jackson, and Ava are studying cells in their biology class. They learned about a type of transport that moves substances through a cell membrane from areas of high concentration to areas of low concentration without using the cell’s energy. What is this type of transport called?

• Passive Transport

• Active Transport

Aria, Mason, and Arjun are conducting a science experiment. They release a small amount of perfume in one corner of the room. After a while, they notice that the scent of the perfume has spread throughout the room. What type of passive transport is responsible for the movement of the perfume molecules from an area of higher concentration to an area of lower concentration?

• Osmosis

• Diffusion

• Facilitated Diffusion

Daniel, Abigail, and Aria are conducting a science experiment. They are observing a process where water molecules move through a semi-permeable membrane from an area of high concentration to an area of low concentration. What is this process called?

• Osmosis

• Diffusion

• Facilitated Diffusion

Anika, Nora, and Emma are studying cells in their biology class. They learned about a process that moves substances through a cell membrane from areas of low concentration to areas of high concentration using the cell’s energy. What is this process called?

• Passive Transport
