FOTOSINTESE
• Sonligenergie, koolstofdioksied en water word gebruik.

• Suurstof en Glukose (‘n suiker) word gevorm.

• Proses vind plaas in chloroplaste van selle wat groen pigment, nl. Chlorofil,
bevat.

• Ensieme in die sel is ook vir fotosintese nodig.

• Fotosintese is ‘n ANABOLIESE (opbouende) proses.

• Woordvergelyking van fotosintese:

water + koolstofdioksied sonlig, chlorofil en ensieme glukose + suurstof

• Chemiese vergelyking van fotosintese:

6H2O + 6CO2 sonlig, chlorofil en ensieme C6H12O6 + 6O2

RESPIRASIE
• Glukose is ‘n energieryke molekule.

• Energie is nodig vir selrespirasie om plaas te vind.

• Oormatige glukose kan in stysel in blare of ander dele van die plant omskep
word.

• Stysel is energieryke molekule, wat energie berg tot plant dit nodig kry.

• Basies teenoorgestelde as fotosintese – Kataboliese proses

• Suurstof en Glukose Koolstofdioksied, Water en Energie

, VEREISTES VAN FOTOSINTESE
• Sonligenergie

• Chlorofil – chloroplaste – mesofilselle

• Koolstofdioksied

• Lug - Stomata - lugruimtes – sponsagtige mesofilselle

• Water

• Grond - Wortelhare - Vervoer deur Xileemvate

• Chlorofil

• Groen pigmente (NB – Skets bl 122)

• Ensieme

• Mesofilselle - nodig om chemiese reaksie te kataliseer

• Ensieme benodig optimale temp. - Denatureer (onomkeerbaar)

PRODUKTE VAN FOTOSINTESE
• Glukose

• Energie kom v sonlig af wat plant opneem.

• Glukose word gebruik tydens selrespirasie.

• Glukose word ook gebruik om ander voedingstowwe te sintetiseer (om ‘n
komplekse stof uit eenvoudiger stowwe te vorm) bv. lipiede, proteïene en
stysel.

• Stysel is vorm van gebergde energie in die plant.

• Suurstof

• Vrygestel as byproduk van fotosintese

• Versprei deur blaar – lugruimtes in sponsagtige mesofilselle – verlaat deur
stomata
