Phtosynthesis
- is the food source for plants
- the way this happens the plant traps the
suns energy in chlorophyll they use the
energy to build up the co2 and h20 into
carbohydrates
- the plant makes glucose. they use this for respiration.
- they also make oxogen this is a waste
gas some is used for respiration but a
lot is given off to plant surroundings
- converting gluecose to other substances
- glucose can be stored as starch
till the plant needs it
- they will use this at
night when there is no
sunlight the plant is not making glucose.
- when producing proteins
they don't just use sugar the
use nit ire ions from the soil.
- gluecose is converted to
suecrose because it dissolves in
water and is easier to trans port
- plant is not just made of sugar but converts
the sugar to make substances such as
cellulose proteins and fats which it needs to grow
- starch can be converted back to glucose for respiration
- starch will not dissolve in water
- starch does not affect the water concentration
