Cell Transport Test

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.

What does selectively-permeable mean?

• Allow certain things to enter and leave the cell

• Nothing gets through

• The cell lets only large substances through

Passive transport requires ________________

• concentration gradients

• no energy

• motion

• energy

Movement of particles from high to low concentration.

• Passive Transport

• Active Transport

Which is true about active transport?

• It requires energy
• it does not require energy
• It moves substances down the concentration gradient
• it moves material from high to low concentration

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole
• nucleus
• cell membrane
• cell wall

Solutes move against the concentration gradient, therefore energy is needed. 

• Passive Transport
• Active Transport

Solutes move with the concentration gradient, therefore no energy is used. 

• Passive Transport
• Active Transport
