Cell Transport, Photosynthesis & Respiration

Movement from an area of high concentration to an area of low concentration (with the concentration gradient/flow) is called....

• Active transport

• Passive transport

Which type of transport uses energy in the form of ATP to transport substances?

• Active transport

• Passive transport

Which type of passive transport focuses on the movement of water through the membrane?

• Facilitated diffusion

• Osmosis

• Diffusion

• active transport

The plant cell has shrunk in size when placed in a liquid solution. What can we determine about the liquid solution?

• liquid solution had higher water concentration than the cell

• liquid solution had lower water concentration than the cell

• liquid solution had the same water concentration as the cell

Water is rushing in this plant cell. This means that the solution has greater/lesser water concentration compared to the plant cell.

• greater

• lesser

• the same

• Cytoplasm

What are (1) the large purple structures (2) the light purple circles with tails?

• phospholipid bilayer,

  protein

This picture shows molecules of red dye that have moved. What is this type of movement called?

• Osmosis; the water molecules are moving from high concentration to low

• Diffusion; the dye molecules are moving from low to high concentration

• Diffusion; the dye molecules are moving from high to low concentration.

• Facilitated diffusion; because the molecules are moving through a protein channel.

Passive transport is when molecules move (fill in blank) the concentration gradient.

• with

• against

• up

• in any direction
