Q

Wat is die fotosintese proses

A
  1. Die blaar absorbeer koolstofdioksied van die lug
  2. Sonlig energie word met behulp van chlorofil geabsorbeer
  3. Die plante se wortels absobeer water
  4. Voedsel glukose word vervaardig met water, koolstofdioksied en ligenergie
  5. Suurstof word as ń by produk vrygestel.
