The kelps are among the largest algae; certain species of Macrocystis and Nereocystis of the Pacific and Antarctic regions exceed 33 metres (100 feet) in length. 1. Algae are the green slimy blanket which covers the rock surface or the top of the ponds or a poorly kept aquarium that have the ability to conduct photosynthesis. Examples are Chlamydomonas, Spirogyra, and Chara; Phaeophyceae – Also called as brown algae, they are predominantly marine. These are eukaryotic organisms, autotrophic in […] Subsequently Whittaker proposed a more systematic and elaborates five kingdom system of classification. Brown algae (class Phaeophyceae) commonly found as seaweeds include kelps and Fucus. They are widely distributed in colder zones and are absent from tropical waters. Algae Classification. Kelp grows in "underwater forests" (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 5 to 23 million years ago. While green and red algae are considered plants (kingdom Plantae), brown algae belong to a different kingdom called Chromista (Cavalier-Smith, 2007). 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. Kelps are large brown algae seaweeds that make up the order Laminariales.There are about 30 different genera. https://www.slideshare.net/KunalSinha12/classification-of-seaweed animal.

He classified all the living organisms under two large kingdoms. dandelions belong to which kingdom. The classification of algae depends on its features. The separation of these three groups is so deep and substantial that in recent classification schemes they are classified into different kingdoms. yeast belongs to which kingdom. seaweed belongs to which kingdom. Plant Kingdom is divided in to: (I) Thallophyta: Various types of microorganisms like algae, fungi and bacteria have been kept under it. These systems of classification of living organisms and their merits and demerits are given below. Algae is a collective term for many organisms, so it is classified into different kingdoms. Algae belongs to four different kingdoms, including the kingdom bacteria, kingdom plantae, kingdom protista and kingdom chromista. protist. Latin ‘alga’ means seaweed. The levels of classification of organisms in order are domain, kingdom, phylum, class, order, family, genus and species. The major characteristics of taxonomic significance used in the classification of algae have been tabulated in Table 5.2. The algae belong to the subphylum Thallophyta of the kingdom Protista in modern classification of organisms.
