Cell Cycle and Diffusion

When particles move from areas of high concentration to areas less concentrated, this has taken place.

• diffusion

• mitosis

• endocytosis

• photosynthesis

What is the longest stage of the cell cycle called?

• Cytokinesis

• M phase

• Interphase

• G1 Phase

During what phase of the cell cycle does the cell grow?

• G1 phase

• S phase

• M phase

• Cytokinesis

What part of the cell cycle results in the splitting into two new cells?

• Interphase

• Mitosis

• Metaphase

• Cytokinesis

Based on the process of diffusion, describe what is happening in the diagram below.

• The molecules do not move.

• The molecules move from inside the cell to outside the cell until they reach equilibrium.

• The molecules move from outside the cell to inside the cell until they reach equilibrium.

• The molecules all move to the inside of the cell.

Simple Diffusion is a process that...

Moves from ​ (a)   concentration. It​ (b)   use energy. It has ​ (c)   ​ move across a membrane. It ​ (d)   use a protein channel (doorway) to help.

• high to low

• low to high

• does

• solutes

• water

• does not

• small solutes

• large solutes

Where will molecule X try to move to?                                                                                                                                                    

• Side A

• Side B

• Out of the box

• Stuck in the membrane

What is the process by which molecules move from an area of higher concentration to an area of lower concentration?

• Osmosis

• Active transport

• Diffusion

• Filtration

Diffusion is the net movement of particles from an area of ​ (a)   CONCENTRATION to an area of ​ (b)   CONCENTRATION

• high

• low
