Photosynthesis & respiration - Coggle Diagram
Photosynthesis & respiration
Light dependant stage
H2O is spilt into O and H
H atoms are fixed to CO2 during carbon fixing to produce glucose
Occurs in thiaklyoids
Oxygen diffuses out of leaves via stoma
CO2 + H20 = O2 + Glucose using light which is absorbed by chloropyll
Light indepentadnt reaction
Carbon fixing
Occurs in the stroma of chloroplasts
Calvin cycle produces 1 glucose for every 6
H attactes to CO2, creating glucose
The chloroplast
Chloropyll
Green light absorbing pigment
Grana
Individaul dics which are stacked to maximise SA for Light dependant reactions
Stacks are called thialkyolids
Stroma
Fluid surounding components of the chloroplast
respiration
releases energy from glucose
in mitachondria
plant and animal cells
needs glucose and oxygen (areobic respiration)
produces
energy
CO2
Water
Glucose + oxygen → carbon dioxide + water + energy
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
types of respiration
aerobic
Uses oxygen
Releases lots of energy
Produces CO₂ + water
anaerobic
Does not use oxygen
Releases less energy
energys used for
Movement
Growth
Active transport
Keeping warm
Repairing cells
Building molecules
Photosyntheses provides the glucose to be broken down in respiration to produce ATP energy
This energy is required for cellurlar process, growth and survival of the organism
Photosynthesis → produces glucose + oxygen → used in respiration
Respiration → produces carbon dioxide + water → used in photosynthesis
