Retake Cell processes/homeostasis 23

When the concentration of sugar in a cell is higher than that of the solution the cell is placed in, what will most likely happen?

• The concentrations will remain the same to maintain homeostasis
• The cell will use a form of passive transport to regulate the internal environment and move materials out of the cell
• The cell will use a form of active transport to regulate the internal environment and move materials out of the cell
• The cell will wait until enough ATP is stored to move materials out of the cell

The _______ carries out photosynthesis in the cell (organelle)

• mitochondria
• chloroplasts
• chlorophyll

Osmosis is important to cells because

• cells are filled with fluids that are made mostly of water
• cells need to get rid of large particles they don't need
• cells need to move from place to place
• cells are usually dry
