Algae may be cultivated for the purposes of biomass production (as in a seaweed cultivator), wastewater treatment, CO 2 fixation, or aquarium/pond filtration in the form of an algae scrubber. [116] Algae bioreactors vary widely in design, falling broadly into two categories: open reactors and enclosed reactors.
A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments.
Green algae are often classified with their embryophyte descendants in the green plant clade Viridiplantae (or Chlorobionta). Viridiplantae, together with red algae and glaucophyte algae, form the supergroup Primoplantae, also known as Archaeplastida or Plantae sensu lato. The ancestral green alga was a unicellular flagellate. [20]
A seaweed farm in Uroa, Zanzibar Algaculture in Kibbutz Ketura, Israel. Algaculture is a form of aquaculture involving the farming of species of algae. [1]The majority of algae that are intentionally cultivated fall into the category of microalgae (also referred to as phytoplankton, microphytes, or planktonic algae).
Kelps can range in size from the 60-centimeter-tall (2 ft) sea palm Postelsia to the giant kelp Macrocystis pyrifera, which grows to over 50 m (150 ft) long [8] [9] and is the largest of all the algae. In form, the brown algae range from small crusts or cushions [10] to leafy free-floating mats formed by species of Sargassum.
Harmful Algal blooms are colonies of microscopic algae that grow out of control. They can be damaging to people, wildlife and the environment. How harmful algal blooms, or colonies of microscopic ...

Pit connections and pit plugs are unique and distinctive features of red algae that form during the process of cytokinesis following mitosis. [56] [3] In red algae, cytokinesis is incomplete. Typically, a small pore is left in the middle of the newly formed partition. The pit connection is formed where the daughter cells remain in contact.
