Diffusion and Osmosis

What is the diffusion of water only across a cell or semi-permeable membrane?

• Osmosis
• Diffusion
• Active Transport
• Passive Transport

What type of cellular transport uses energy?

• Passive Transport
• Active Transport

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration
• when placed in a isotonic solution
• when placed in a solution containing a low pH
• when placed in a solution containing distilled water

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration
• when placed in a isotonic solution
• when placed in a solution containing a low pH
• when placed in a solution containing distilled water

Diffusion and Osmosis are examples of...

• Active Transport
• Passive Transport

During diffusion

• substances (things) moves from high to low concentration
• water moves when energy is used
• large or oddly shaped molecules move across a cell membrane
• water moves from high to low concentration

Where is there a high concentration of water?

• in the flower
• cannot be determined by picture.
• in the vase
• in the leaves

Osmosis

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration
• the diffusion of particles from an area of high concentration to an area of low concentration
• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration
• the diffusion of particles from an area of low concentration to an area of high concentration

Why are diffusion and osmosis important to cells?

• It allows them to take in materials/substances without using energy.

• It allows them to reproduce.

• It allows them to absorb sunlight.

• It allows cells to use all energy.

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.

• osmosis
• equilibrium
• diffusion
• hypertonic
