Any Q

In plants, carotenoids are essential for photosynthesis and photoprotection. They play critical roles as light harvesting pigments and structural components of photosystems. Carotenoids also provide precursors for the biosynthesis of phytohormones abscisic acid (ABA) and strigolactones (SLs). 21 янв. 2022 г.


What is the importance of carotenoids?

Carotenoids are lipid-soluble pigments that give fruits and vegetables their color. They have antioxidant and anti-inflammatory properties that are important in eye health in protecting retinal tissue from blue shortwave light damage.

What does carotene do in plants?

Carotenes contribute to photosynthesis by transmitting the light energy they absorb to chlorophyll. They also protect plant tissues by helping to absorb the energy from singlet oxygen, an excited form of the oxygen molecule O which is formed during photosynthesis.

What is the most important job of carotenoids pigments in plants?

Carotenoids serve two key roles in plants and algae: they absorb light energy for use in photosynthesis, and they provide photoprotection via non-photochemical quenching.

What is the important role of carotenoids for a plant to perform photosynthesis?

Carotenoids are ubiquitous and essential pigments in photosynthesis. They absorb in the blue-green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and so expand the wavelength range of light that is able to drive photosynthesis.
