1
10/11 Turgor Pressure The outward force applied on the cell wall of plants from water within the cell Example: Plants wilt when turgor pressure is low.
2
10/12 TEST STUDY!!!
3
10/13 Force A push or pull that changes the movement, direction, or shape of an object
4
10/14 Work The transfer of energy Example: If you put energy into an object, then you do work on that object.
5
10/17 Geotropism/Tropism Growth or movement stimulated or in response to gravity. Tropisms occur when plants respond to external stimuli.
6
10/20 Simple Machine A device that makes work easier by changing the direction or size of the applied force.
7
Tropisms A plant’s growth response to an external stimulus such as touch, light, or gravity Response can be positive(towards the stimuli) or negative(away from the stimuli) Example: Geotropism: plants response to gravity
8
10/18 Osmosis Movement of water across a membrane, such as a cell membrane.
9
Diffusion Movement of a molecule from an area where it is in higher concentration to an area where it is lower.
10
Hypotonic A solution in which the solute concentration is greater than the solution surrounding it, causing water to move into the cell. Example: your potato soaked in plain water, or the wilted lettuce soaked in water.
11
Write both in your SHOES ( 2 Separate Words) Joule (J)Newton (N) The SI unit used to express work and energy Example: A joule is equivalent to 1 Newton-meter (N∙m). The SI unit of force Example: It takes about 45 newtons (N) of force to lift a small dog.
12
Joule (J) The SI unit used to express work and energy Example: A joule is equivalent to 1 Newton- meter (N∙m).
13
Newton (N) The SI unit of force Example: It takes about 45 newtons (N) of force to lift a small dog.
14
Control Group In an experiment, a group that is left alone from the experiment testing, to let run natural course.
15
Respiration The process by which cells break down simple food molecules to release the energy they contain.
