Similarity in pigment composition in algal groups

Pigments are the colored compounds that are responsible for the capture of light energy during photosynthesis. The various algal groups have different pigment compositions that enable them to absorb light of different wavelengths.

Among the given options, the algal groups that have similarity in pigment composition are kelps and diatoms.

Kelps:

Kelps are a type of brown algae that belong to the order Laminariales. They are multicellular and can grow up to several meters in length.

Pigment composition of kelps:

- Chlorophyll a: It is the primary photosynthetic pigment that absorbs light in the blue-violet and red regions of the spectrum.
- Chlorophyll c: It is a secondary pigment that absorbs light in the green region of the spectrum.
- Fucoxanthin: It is a brown pigment that gives the kelps their characteristic color. It absorbs light in the blue-green region of the spectrum.

Diatoms:

Diatoms are unicellular algae that belong to the phylum Bacillariophyta. They are found in both marine and freshwater environments and are an important component of the phytoplankton.

Pigment composition of diatoms:

- Chlorophyll a: It is the primary photosynthetic pigment that absorbs light in the blue-violet and red regions of the spectrum.
- Chlorophyll c: It is a secondary pigment that absorbs light in the green region of the spectrum.
- Fucoxanthin: It is a brown pigment that gives the diatoms their characteristic color. It absorbs light in the blue-green region of the spectrum.

Similarity in pigment composition:

As we can see from the above pigment compositions, both kelps and diatoms have the same types of pigments - chlorophyll a, chlorophyll c, and fucoxanthin. This similarity in pigment composition enables them to absorb light of similar wavelengths and utilize the available light energy efficiently.

Hence, the correct answer is option C - Kelps and diatoms.

Yes answer will be diatoms and kelpsas both of them contain chlorophyll a and c💯💯💯💯surehope u got it?
