1. High soil moisture leads to decreased photosynthesis.
2. Carbon capture is performed by the green parts of plants via photosynthesis.
3. To transform atmospheric CO2 into organic molecules, plants can use the energy from
4. Plant respiration captures CO2.
5. The annual cycle of photosynthesis mainly follows
6. Photosynthesis of a tree canopy is driven or influenced by
7. De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
8. In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis – if other factors are favourable.
9. A complex microbiota lives belowground, releasing carbon dioxide to the soil.
10. Transpiration decreases as air becomes drier.
11. Carbon becomes locked as part of the accumulating plant biomass as plants grow.
12. The effect of light on photosynthesis has a clear saturating pattern: more light results in more photosynthesis but eventually leaves cannot take full advantage of all the extra light.
13. Leaf area increases with stand age, resulting in a decreasing rate of photosynthesis in the stand.
14. The rate of respiration decreases with temperature.
15. At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
