Mind MapPhotosynthesis
requirements occurs inside
process consists of
rate can be affected by products
function in cells
converted to
1. chlorophyll
2. carbon dioxide
3. sunlight
4. water
chloroplasts
1. light reactions
2. dark reactions
1. light intensity
2. carbon dioxide concentration
glucose oxygen
provides energy
1. amino acid
2. sucrose
3. starch
4. cellulose
5. fats
Mind MapRespiration
oxygen is not required
leads to
can be classified into
as
examples
food is oxidised to r
eleaseoxygen is required
produces produces
can be used in
energy
1. ATP
2. Heat
aerobic respiration
larger amount of
energy
anaerobic respiration
smaller amount of
energyalcoholic
fermentation
1. brewing and wine making
2. bread making
lactic acid fermentation in
muscles
oxygen debt and fatigue
Mind MapPlants
need
2 major elements
can be obtained by adding
include
mode of nutrition
mainly through
in daytime
at night(or in the
dark)
occurs in the leaves most
autotrophic nutrition
mineral salts
1. nitrogen
2. magnesium
fertilizers
1. chemical fertilizers
2. natural fertilizers
gaseous exchange
stomata on leaves
respiration and photosynthesis
respiration only
Mind Map
the process of losing water from the surface to the
atmosphere
is the creates importance
transpiration
loss of water from plant
transpiration pull
1. carries and helps absorbing dissolved mineral salts
2. produces cooling effect
the rate is affected by
1. light intensity
2. temperature
3. relative humidity
4. air movement
Plants
