The diatoms are one of the largest and important groups of freshwater or marine organisms. They are oxygenic photosynthetic organisms. Most benthic diatom algae are delicate unicellular organisms or multishaped colonies (Fig. 2.6).
Which algae live in deep sea?
Red algae
Explanation: Red algae is mostly likely to be found in deep water. This has to do with the different wavelengths of light and how deep they can penetrate water. Red light has the longest wavelength of the visible spectrum which means it penetrates water the least.
Is Dictyota unicellular?
Why Laminaria is called Devil’s apron?
