Is chlorophyll b necessary for photosynthesis?

Answer 1

Chlorophyll is necessary for photosynthesis. It is located in the chloroplast and helps the plant with photosynthesis by helping the plant trap in sunlight. Without this, the plant would struggle to photosynthesize properly.

Hope this helps :D

Answer 2

Yes, because chlorophyll gives foliage the green pigment needed for photosynthesis to occurr. It is needed because with it there are chloroplasts in the foliage which absorb the sunlight producing oxygen for us life forms.

Answer 3

Yes. Chloroplasts are the organelles where the light reactions take place. The light reactions harvest the energy from the sun's rays, store that energy in energetic molecules (NADPH and ATP) which are then used in the Calvin cycle to drive the synthesis of organic molecules from CO2. The Calvin cycle does not take place inside the chloroplasts.

Answer 4

No. Cyanobacteria photosynthesise using chlorophyll (just like the chloroplasts in plant cells), but some other bacterial groups use similar but distinct photosynhtetic pigments called bacteriochlorophylls, (some of which) reduce sulphides instead of water and produce excess sulphur instead of excess oxygen. Examples of photosynthesising bacteria that use bacteriochlorophylls rather than chlorophyll in the strict sense include Chloroflexi, Heliobacteria, purple bacteria, and green sulphur bacteria.

Other photosynthetic pigments include phycocyanin, carotenes, and xanthophylls in green algae, phycoerythrin in red algae (rhodophytes) and fucoxanthin in brown algae and diatoms.

Answer 5

Yes! Without it, plants would not be able to convert light into energy. (Planets mainly absorb light from the Blue and Red ends of the spectrum (around 430nm, and 650nm).

Answer 6

Chlorophyll makes makes plant absorb food or nutrients through sunlight

Answer 7

Yes chlorophyll is the green pigment in plants, it is necessary for photosynthesis because it is what absorbs the sunlight.
