What type of transport is this?

In active transport, substances move from:

• High concentration to low concentration

• Low concentration to high concentration

Whereas _____ involves bringing particles into the cell, _____ involves expelling particles out of the cell.

• exocytosis, endocytosis

• cytoplasm, nucleus

• endocytosis, exocytosis

Which one is the definition of active transport?

• Movement of particles through the cell membrane from a region of lower concentration to a region of higher concentration using energy in the form of ATP.

• Passage of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane.

• Net movement of molecules from a region of higher concentration to a region of lower concentration. Molecules move down a concentration gradient.

• Net movement of molecules from a region of lower concentration to a region of higher concentration. Molecules move down a concentration gradient.

The roots of a plant contain a high concentration of minerals while the soil contains a lower concentration. The roots absorb minerals from the soil. This is an example of:

• passive transport

• active transport

• diffusion

• osmosis

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)

• Active uses ATP (energy) and passive does not need energy

• Active stores transport proteins and passive releases them

• Active uses hormones and passive does not

What might happen if a cell did not have any ATP/energy?

• It would not have enough energy to perform active transport.

• Its cell membrane would break.

• The transport proteins would not be needed.
