What process involves the movement of solvent through a semi-permeable membrane from a region of low solute concentration to a region of high solute concentration?

Which of the following is a feature of exocytosis but not endocytosis?

What is essential for diffusion?

Which process allows the movement of molecules that are too large to pass in through a cell surface membrane?

What is facilitated diffusion?

Which of the following is required for osmosis to occur?

Which statements are characteristics of diffusion through membranes? ( I- Polysaccharides can be transported; II- It can be facilitated by special channels; III- It is affected by concentration gradient )

What is the correct sequence of events during exocytosis?

I- Formation of a vesicle by the Golgi apparatus.

II- Secretion of the vesicle's contents.

III- Fusion of the vesicle with the plasma membrane.

IV- Movement of the vesicle towards the plasma membrane.

The sodium-potassium pump transports

Substances that can pass through cell membrane by diffusion include:-

Which of the following correctly describes exocytosis?

Pinocytosis involves the transport of

A saturated suspension of starch is enclosed in a bag formed from dialysis tubing, a material through which water can pass but starch cannot. The bag with the starch is placed into a beaker of distilled water. All of the following are expected to occur except

The energy needed to power the sodium-potassium pump is provided by the



This test concerns on the following assessment statement from the IB syllabus guide 2009:-

2.4.4, 2.4.5, 2.4.6, 2.4.7, 2.4.8

2.4.4:- Define diffusion and osmosis.

2.4.5:- Explain passive transport across membranes by simple diffusion and facilitated diffusion.

2.4.6:- Explain the role of protein pumps and ATP in active transport across membranes.

2.4.7:- Explain how vesicles are used to transport materials within a cell between the rough endoplasmic reticulum, Golgi apparatus, and plasma membrane.

2.4.8:- Describe the fluidity of the membrane allows it ti change shape, break and re-form during endocytosis and exocytosis.
