Cell Transport

What does “high concentration area” mean?

• Spread out
• Tightly packed together
• Uncrowded
• Spacious

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

• diffusion
• mitosis
• endocytosis
• photosynthesis

What process occurs when WATER diffuses across a membrane?

• endocytosis
• mitosis
• osmosis
• nuclear fission 

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.

The picture  is an example of _________________.

• isotonic
• diffusion
• osmosis
• active transport

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

What does selectively-permeable mean?

• Allow certain things to enter and leave the cell

• Nothing gets through

• The cell lets only large substances through

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Cell membrane surrounds a particle and encloses it (for large particles)

• Endocytosis
• Exocytosis
• Permeable
• In high concentration
