Go to Chapter 4 in your online textbook and define these words
Vocabulary Defined• osmosis- the diffusion of water through a semipermeable membrane• diffusion- the movement of particles from regions of high
concentration to low concentration (no energy required)• semipermeable- only certain substances can pass through
Examples Osmosis/Diffusion
Examples of Osmosis•Red blood cells•Plant cells
Moving Small Particles•passive transport-movement of particles across a cell
membrane without the use of energy (move from high concentration to low concentration)• active transport-movement of particles to requires
energy from low concentration to high concentration•diffusion
Examples Passive/Active Transport
Moving Large Particles• endocytosis-active transport process by which a cell surrounds a large
particle such as a protein and encloses the particle in a vesicle to bring the particle “into” the cell• exocytosis- active transport process that the cell uses to enclose
waste materials that are inside the cell to release them out of the cell
Examples of Endo and Exo Cytosis

Objectives•Describe photosynthesis and cellular respiration•Compare cellular respiration with fermentation
Vocabulary• photosynthesis• cellular respiration• fermentation• pigments
Photosynthesis and Respiration
Cellular respiration
• Chemical process that takes place in cells• Takes place in the mitochondria• Most of the energy released is used to maintain body temperature
C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy
Fermentation• The breakdown of food to obtain energy without the use of oxygen• Examples: leg cramps (burning sensation)• One type: when muscles produce lactic acid when oxygen is unavailable• Bacteria, fungi, and yeast are other examples
