Which of these statements are true?
In Diffusion, substances move from low to high concentration.
In Active Transport, dissolves molecules move from low to high concentration.
In Osmosis, water molecules from a dilute solution to a concentrated solution across a semi-permeable membrane.
In Diffusion, substances move from a high to low concentration.
In Active Transport, dissolved molecules move across a cell membrane from a low to high concentration.
In Active Transport, dissolved molecules move across a cell membrane from a high to low concentration.
Osmosis is th diffusion of water molecules from a dilute solution to a concentration solution across a semi-permeable membrane.
Osmosis is th diffusion of water molecules from a concentrated solution to a dilute solution across a semi-permeable membrane.
Active transport moves up down( up, down ) a concentration Gradient
Diffusion moves ❌ a concentration gradient.
Active transport does need energy to work.
Active transport does not need energy to work.
Diffusion does need energy to work.
Water molecules cannot can( cannot, can ) diffuse freely across a semi-permeable permeable( semi-permeable, permeable ) membrane, Sugar molecules cannot can( cannot, can ) diffuse freely.
Urea Glucose( Urea, Glucose ), Oxygen & Water Carbon dioxide( Water, Carbon dioxide ) can diffuse into cells
❌, ❌ and excess water diffuse out of cells.
Osmosis is similar to diffusion but only explains the movement of water molecules.
Active Transport is similar to diffusion but only explains the movement of water molecules.
Within the body, Glucose is actively transported from the small intestine into the blood across villi.
Within the body, Urea is actively transported from the small intestine into the blood across villi.
In plants, Glucose are actively transported from the soil through root hair cells.
In plants, Mineral Ions are actively transported from the soil through root hair cells.
An increased concentration gradient causes a higher rate of diffusion.
An increased concentration gradient does not effect the rate of diffusion.
An higher temperature causes a higher rate of diffusion.
An lower temperature causes a higher rate of diffusion.
