Question

Carmen conducts tests on a sample of four autotrophic organisms to determine the type of photosynthetic pigment present. Match the pigments to the species in which they are present. phycobilin sea lettuce phycocyanin diatoms chlorophyll b cyanobacteria fucoxanthin red algae

Answer 1

cyanobacteria - phycocyanin, phycobilin

diatoms - fucoxanthin

sea lettuce - chlorophyll b

red algae - phycobilin

Step-by-step explanation:

- Cyanobacteria, which are also called blue green algae, are autotrophic organisms i.e. they perform photosynthesis by capturing light energy using pigments. They possess most of the blue phycobilin pigment called PHYCOCYANIN.

- Diatoms are algae under the division bacilliarophyta. They are single-celled photosynthetic algae which uses pigments that include FUCOXANTHIN, a type of xanthophyll pigment.

- Sea lettuce, belong to the group Chlorophyta and is autotrophic i.e. undergo photosynthesis. It makes use of CHLOROPHYLL pigments (chlorophyll b) like other plants.

- Red algae uses the red PHYCOBILIN called Phycoerythrin, which is an accessory photosynthetic pigment, to perform photosynthesis.
