New cards
Plant tissue
Carbs, proteins, lipids

New cards
Photosynthesis chemical equation
6CO2 + 6H20 —> C6H12O6 + 6O2
3
New cards
Why is sunlight needed in p/s?
Provides light energy that is then converted into chemical energy in bonds of glucose
4
New cards
Why is glucose produced in p/s?
Simple sugar used in respiration to release more energy.
Used to make cellulose cell walls.

New cards
How is glucose stored in plants?
Starch- insoluble
Sucrose- soluble and transported around plant (phloem)
Fructose- in fruits

Fructose- in fruits
6
New cards
Chlorophyll
Molecule that captures light energy from the sun, found in palisade mesophyll
7
New cards
4 leaf adaptations
Long and broad- large surface area to absorb light
Green- contains chlorophyll that captures light
Network of veins- carry water and other substances
Thin- allows diffusion

New cards
Investigating the effect of light on gas exchange by a leaf
4 sealed boiling tubes containing large leaves and hydrogen carbonate indicator
1 tube in bright light, 1 in dark, 1 in muslin and 1 control
The more p/s, the more CO2, the darker (yellow-purple)

New cards
Testing leaf for starch
Remove leaf
\
Leave heat in boiling water to denature enzymes
Add boiling tube of ethanol in double boiler
Add leaf to remove all chlorophyll
Wash leaf in cold water
Add iodine solution
If starch present, turns black
