Answer:
Water temperature leads to production of reactive oxygen species which later affects the products and by products of photosynthesis
Explanation:
There are several factors associated with water that can affect the coral bleaching.
A) low water temperature
B) Presence of chemical contaminants in the sea water
When both the temperature of sea water and solar radiations are high enough, photosynthesis is intensely stressed due to which reactive oxygen species (ROS) are produced that can damage lipids, proteins, carbohydrates, and DNA. In plants, photosystem II (PSII) activity gets inhibited by ROS as it causes photo inhibition. In case if it damages the
thylakoidal membranes, energy decoupling of the electron transport in both PSI and PSII causes reduced ATP and NADP production. This happens because excess amount of electron are produced reduces oxygen instead of NADPH and thus produce superoxide ion.
In algae’s, photosynthesis is affected due to these ROS. Instead of retaining the sugars and amino acids, the cell deliver more than 90% of their produce to the host cells.
The great barrier reef is formed by the organism that belongs to the phylum concentrates. A few examples of an organism are as follows:-
- Sea anemone
- Gorgonia
- Sea fan
These are the species that help in formation of the great barrier reef.
ATP, NADP, and sugars are the product of the photosynthesis process. These are the by-products of the reactions. Water in the ocean and the sunlight trapped by the chloroplast are used by the plant.
These by-products are used by the plants for making energy in the dark reaction.
All the raw material is present in the water.
