Week 13 Cell Processes ; Osmosis Diffusion, Active Transport


Monday Nov 24 2013
QFD: Weakness of attitude becomes weakness of character. Albert Einstein
?FD: Draw a picture of molecules for an Osmotic condition
Objective: BSS 1A Students know cells are enclosed within semipermeable membranes that regulate their interaction with their surroundings.
1) Students will demonstrate their knowledge by completing a word vocabulary matrix and by describing the terms osmosis, diffusion and active transport in a perfect paragraph

Diffusion: movement of molecules, from a region of high concentration to a region of low concentration.
– Oxygen diffuses into cells, and the waste carbon dioxide diffuses out.
Osmosis: movement of water molecules, across a partially permeable membrane, from a region of high concentration of water to a low concentration of water molecules.
– It allows plants to take in water through their roots.
– It is used in kidney dialysis machines to filter the blood.
Semi-permeable membrane
– Small molecules, such as water can pass through the small holes in the membrane…
– But larger molecules like sugar cannot pass through the membrane.

QFD : Everyday can be a new beginning to be thankful for:
?FD : Describe the potassium mentioned in the video from yesterday

Objective: BSS 1a Students know cells are enclosed within semipermeable membranes that regulate their interaction with their surroundings.
1) students will demonstrate their knowledge of osmosis, diffusion, and active transport by completed 3 handouts with differentiated questions
me·tab·o·lism (m-tb-lzm)
n.
1. The chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.

2. The processing of a specific substance within the living body: water metabolism; iodine metabolism.
