The Selectively permeable Cell Membrane Diffusion, osmosis, and active transport.

Osmosis and Diffusion Semi-Permeable membrane – allows some things through and keeps other things out (Also called selectively permeable)

Structure and Function

Requires energy to move substances across the membrane. -Small & large particles.

Diffusion Particles naturally travel from areas where they are crowded to areas where they are less crowded.

Passive vs. Active Transport. Passive Transport Does NOT require energy Moves substances from higher to lower concentration.

Materials move across membranes because of concentration differences.

Transport across Plasma membranes. Membranes Are differentially permeable – Permeable to SOME substances. The membrane selects what substances pass through.

Presentation transcript:

Diffusion The movement of particles across the cell membrane from an area of high concentration to low concentration Type of passive transport (does not require energy)

Osmosis The movement (diffusion) of water through a cell membrane Type of passive transport (does not require energy)

DNA Deoxyribonucleic acid; a molecule that is present in all living cells and that contains the information that determines the traits that a living thing inherits and needs to live

Protein A molecule that is made up of amino acids and that is needed to build and repair body structures and to regulate processes in the body

Carbohydrates A class of molecules that includes sugars, starches, and fiber Mitochondria need these carbohydrates to produce energy Carbohydrates are made from the process of photosynthesis (chloroplasts)
