Algae - Classification of algae: The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since 1960. Early morphological research using electron microscopes demonstrated differences in features, such as the flagellar apparatus, cell ...

en.wikipedia.org/wiki/Algae

Algae (/ ˈ æ l dʒ i, ˈ æ l ɡ i /; singular alga / ˈ æ l ɡ ə /) is an informal term for a large, diverse group of photosynthetic eukaryotic organisms that are not necessarily closely related, and is thus polyphyletic.Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow ...

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.

Algae belongs to four different kingdoms, including the kingdom bacteria, kingdom plantae, kingdom protista and kingdom chromista. The classification of algae depends on its features. Algae is a collective term for many organisms, so it is classified into different kingdoms. The majority of algae are plants, so they are in the kingdom plantae.

Algae Reproduction, Identification and Classification. Algae are photosynthetic organisms belonging to the kingdom Protista. Alga is the singular of algae with a changing size from microscopic unicellular micro-algae (Chlorella and Diatoms) to large massive kelps that are usually a length extending in meters (200 feet) and then there's brown alga.

The major characteristics of taxonomic significance used in the classification of algae have been tabulated in Table 5.2. These characteristics include the photosynthetic pigments, nature of photosynthetic reserve materials, the composition of cell wall or absence of cell wall, cellular and thallus morphology and reproductive behaviour.

Algae Classification. There is three main Algae classification: Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b. Examples are Chlamydomonas, Spirogyra, and Chara; Phaeophyceae – Also called as brown algae, they are predominantly marine. They have chlorophyll a, c, carotenoids and xanthophyll ...

Algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length. Their photosynthetic pigments are more varied than those of plants, and their cells have features not found among plants and ...

Thus, the traditional plant kingdom comprised bacteria, algae, plants and fungi . Demerits or Limitations: (a) The two kingdom system of classification did not indicate any evolutionary relationship between plants and animals. (b) It grouped together the prokaryotes (bacteria, BGA) with other eukaryotes.

Most biologists divide the living world into five "Kingdoms". These Kingdoms are: 1. Kingdom Monera 2. Kingdom Protista 3. Kingdom Fungi 4. Kingdom Plantae 5. Kingdom Animalia Principles of algal classification Although quite simple in form, the algae are an extremely diverse group. They vary in
