Algae are chlorophyll-bearing, simple, thalloid, autotrophic and largely aquatic (both fresh water and marine) organisms. They have unicellular and non-jacketed sex organs. Most of the members have one or more storage bodies called pyrenoids located in the chloroplasts

Dear student

Prescott, G. W. (1969) defined algae as those chlorophyll-bearing organisms (and their colourless relatives) which are thalloid, i.e., having no true roots, stems and leaves or leaf-like organs.

Pyrenoids are sub-cellular micro-compartments found in chloroplasts of many algae, and in a single group of land plants, the hornworts. Pyrenoids are associated with the operation of a carbon-concentrating mechanism (CCM).

The majority of algae live in aquatic habitats Yet, the word "aquatic" is almost limited in its ability to encompass the diversity of these habitats. These organisms can thrive in freshwater lakes or in saltwater oceans

And it is also characterised by Unicelled sex organ.
