Warm-Up

• Compare the function of the cell wall and the cell membrane in plant and animal cells.

• Describe the characteristics and role of the nucleus.

• What are two ways cells can differ?

• What organelles are found in the cytoplasm and what are their functions?

The Cell in its Environment

(Set up for Cornell Notes)How big is a cell?

CELL MEMBRANE

• Selectively Permeable: Some substances can go through it while others cannot.

DIFFUSION

• Molecules move from an area of higher concentration to an area of lower concentration.

OSMOSIS

• Diffusion of water through a selectively permeable membrane.

Cornell Notes

• Selectively permeable

• Diffusion

• Osmosis

• Some substances can pass through the membrane while others cannot.

• Molecules move from an area of higher concentration to an area of lower concentration.

• The diffusion of water molecules through a selectively permeable membrane.

ACTIVE TRANSPORT

• Movement of materials through a cell membrane using energy.

ACTIVE TRANSPORT

• Movement of materials through a cell membrane using energy.

Passive Transport

• (THE OPPOSITE OF ACTIVE IS PASSIVE TRANSPORT)

• Does not require energy to pass particles through the membrane

Movement of Materials

• Active Transport

• Passive Transport

• Movement of materials through a cell membrane using energy.

• Does not require energy to pass particles through the membrane

TRANSPORT PROTEINS

• Proteins in the cell membrane that carry molecules using energy.

ENGULFING

• A cell can also move materials by engulfing (also uses energy).
