In The Pond: A Guide to Algae

Author:

Algae is primitive chlorophyll in a large and diverse group of autotrophic organisms, all of which are simple. They are unicellular and multicellular. These organisms lack any true stems, leaves, or roots such as plant life does. One of the largest and most complex forms of marine algae is seaweed. Algae can be found in a wide number of bodies of water, and also in fish tanks that do not get cleaned frequently.

Algae Makeup

Algae are a eukaryotic organism which means that they have a membrane bound nuclei. Algae are scientifically categorized depending on their colors. They contain chlorophyll and color pigments that trap light from the sun. The light that has been trapped is then converted into food molecules using photosynthesis and can store energy in a form of carbohydrate.

  • Algae Symbiosis: Various in depth look into various forms of algae. The makeup of algae and what they can be used for.
  • Algae: Overview of algae, and what they come from, made up of, and their many uses in the world today.
  • Protist Kingdom: Research and information on the protista group including algae.
  • Eukaryotes: Long line of Eukaryotes with in depth information for each section.
  • The Origins: Information regarding the origins of these algae plants, and their classification.


Archaeplastida

Archaeplastida are a group of eukaryotes. They are made up of red and green algae, long plants, and also a small group of glaucophytes. The Archaeplastida cells lack centrioles, contain mitochondria with cristaes that are flat. They store their foods in a starch format. Red algae are pigmented with chlorophyll A and phycobiliproteins. Green algae and land plants are pigmented with chlorophylls A and B, but lack any phycobiliproteins in their makeup. Glaucophytes have cyanobacterial pigments.


Rhizaria

Rhizaria are a taxonomic kingdom in the subkingdom Biciliata which has many protists. They are a species that are rich in a super group of unicellular eukaryotes. They are mostly amoeboids with filose, microtubule supported pseudopods, or reticulose. They include chlorarachniophytes and euglenids.

  • Chlorarachniophytes: Diverse in depth look into this group of Rhizaria. Slides that show this group are also present on this website.
  • Eukaryotes: Overview of all the eukaryotes in this classification including Rhizaria, chlorarachniophytes, and euglenids.
  • Rhizaria: Information on the Rhizara group, and what good it can bring into the world. Goes into depth about the various sub classes as well.
  • Tree of Rhizaria: Rhizara tree, and explanations of each of the classes in separate links on the tree.

Chromista

Chromista are a super group of eukaryotes that are probably polyphyletic. They can be treated as their own kingdom or even included in the kingdom Protisa. This group contains algae that have chloroplasts that contain chlorophylls A and C. They also include colorless forms that closely relate to the group. They are believed to have come from red algae.

  • Dinoflagellates: Overview of Dinoflagellates and what they consist of within this small sub group.
  • Introduction to Chromista: Everything you wanted to know about this super group is right here on this website with colorful pictures and graphs.
  • Dinoflagellates: Information and classification on what Dinoflagellates are, and what they are made from, where they originated from, and what they can do for the water.
  • Identifying Harmful Dinoflagellates: Overview of harmful Dinoflagellates in marine life, and what can be done to minimize them.
  • Cryptophyta: Information on each of the Cryptophyta and how to identify them.

Cyanobacteria

Cyanobacteria is also known by other names such as blue-green algae, Cyanophyta, and blue-green bacteria. It is a phylum of bacteria that can obtain energy through photosynthesis. The name comes from the Greek word, 'blue.' The endosymbiotic theory leads us to determin that chloroplasts in plants and the algae have evolved from cyanobacteria by endosymbosis.
