ENZYMES that control most chemical reactions
CELL MEMBRANE- Holds cell together, controls what goes in and out

Particles Move About RANDOMLY and after a bit end up EVENLY SPACED.

DIFFUSION

Gradual Movement of particles from places where there are lots of them to places
where there are few of them
From HIGH CONCENTRATION to LOW CONCENTRATION
Passive movement
Happens in both LIQUIDS and GASES-Particles are FREE TO…

Produces GLUCOSE using SUNLIGHT
Produces food in plants
Happens in leaves
Happens in CHLOROPLASTS which contain CHLOROFYLL
CHLOROFYLL absorbs SUNLIGHT which converts its carbon dioxide and water into
GLUCOSE. OXYGEN IS ALSO PRODUCED.

4 THINGS ARE NEEDED FOR PHOTOSYNTHESIS TO HAPPEN:

LIGHT from sun
CARBON DIOXIDE
CHLOROFYLL- green substance absorbs…

If plant gets too low ­ enzymes and other reactions get damaged- 45 degrees

You can artificially create the ideal conditions for farming

Greenhouses

Traps sun's heat so that temperature doesn't becoming limiting factor
Winter- heater is used to keep ideal levels
Summer- can get too hot- ventilation is used…
