Explanation:
The plants in direct sunlight would grow more quickly than those under normal conditions.
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and inorganic carbon dioxide while oxygen (from the light reaction) is released.
In direct sunlight, the plants experience greater light intensities and higher temperatures. An increase in both light intensity and temperature increases the photosynthetic rate.
Further Explanation:
This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
The energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.
Additionally,
- water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
- This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
- Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.
More specifically, the temperature of their environment, along with the species-specific temperature requirements have major impacts on photosynthetic rates and thus, plant growth.
Plants usually grow more quickly with an increase in their environmental temperatures. Every plant species has a specific range of temperature:
- An optimal temperature- for the best possible growth
- A Minimum temperature- (or basal temp) the lowest temperature capable of triggering growth
- A Maximum temperature- the highest tolerable temperature capable of triggering growth
Similarly, increasing light intensity increases the rate of photolysis. This leads to more NADPH availability for the dark reactions and an increase in the photosynthetic rate.
