The method in which water moves, for example, water entering a plant cell is...?

• Active Transport

• Respiration

• Osmosis

• Facilitated Diffusion

There are two methods for transporting molecules within a cell, they are...?

• Active Transport

• Passive Transport

• Chemical Diffusion

• Electromagnetic Pathways

What is the process by which water molecules move across a cell membrane from an area of high concentration to an area of low concentration?

• osmosis

• facilitated diffusion

• active transport

• diffusion

Which type of cellular transport requires energy?

• Active transport

• Osmosis

• Facilitated diffusion

• Passive transport

What is the process by which large molecules are taken into the cell by engulfing them within the cell membrane?

• phagocytosis

• osmosis

• exocytosis

• endocytosis

What is the process by which large molecules are taken out of the cell by transporting them within a vesicle outside the cell membrane?

• phagocytosis

• osmosis

• exocytosis

• endocytosis

Which type of cellular transport requires a transport protein?

• Facilitated diffusion

• Active transport

• Passive transport

• Osmosis

Dialysis is a type of diffusion that...?

• is an ion-exchange membrane separation process, driven by a concentration gradient, mush like diffusion, to clean the blood

• helps molecules move across a membrane using channel proteins to move molecules depending on their charge

• is exactly like osmosis since only water moves through the dialysis membrane

• is a type of active transport since it is used for transporting large molecules

What is a concentration gradient?

• is a just a region of space over which the concentration of a substance changes, and substances will naturally move down their gradients, from an area of higher to an area of lower concentration

• is a just a region of space over which the concentration of a substance changes, and substances will naturally move up the gradients, from an area of lower to an area of higher concentration

• is a just a region of space over which the concentration of a substance changes, and substances will naturally move opposite their gradients, from an area of lower to an area of higher concentration

• DNA translationis a just a region of space over which the concentration of a substance remains the same, and substances will naturally move down their gradients, from an area of higher to an area of lower concentration
