Who proposed 9 Kingdom classification?

By 1981, Cavalier-Smith had divided all the eukaryotes into nine kingdoms. In it, he created Chromista for a separate kingdom of some protists.

Who discovered algae?

Jean Pierre Étienne Vaucher (1803) was perhaps the first to propose a system of classification of algae, and he recognized three groups, Conferves, Ulves, and Tremelles.

What is the largest algae?

Giant kelp
Giant kelp is the worlds largest species of marine algae. In the United States, it can be found along the west coast, especially around southern California where it grows in dense patches, or kelp forests.

What is the scientific name of algae?

division Chlorophyta (green algae) division Chromophyta.

Who is called Father of phycology?

History of phycology

Lamouroux and William Henry Harvey to create significant groupings within the algae. Harvey has been called “the father of modern phycology” in part for his division of the algae into four major divisions based upon their pigmentation.

What is green algae called?

Chlorophyta
Chlorophyta are commonly known as green algae and sometimes, loosely, as seaweed. They grow primarily in freshwater and saltwater, although some are found on land. They may be unicellular (one cell), multicellular (many cells), colonial (a loose aggregation of cells), or coenocytic (one large cell).

Why do we study algae?

Algae are important as primary producers of organic matter at the base of the food chain. They also provide oxygen for other aquatic life.

Who studied algae?

phycologist
The study of algae is called phycology, and a person who studies algae is a phycologist.

What is the size of algae?

Algae have a great range of shapes and sizes, from spherical cells with 0.5 μm diameter to 60 m long multicellular thalli. There are about 72,500 validly described species of algae; they live in the top 300 m of marine and inland waters, and on land, as free-living organisms or in symbiosis.

What is the structure of algae?

Algal cells are eukaryotic and contain three types of double-membrane-bound organelles: the nucleus, the chloroplast, and the mitochondrion. In most algal cells there is only a single nucleus, although some cells are multinucleate.

What are the characteristics of algae?

Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Algae can be multicellular or unicellular. Unicellular algae occur most frequently in water, especially in plankton.

What is life cycle of algae?

The three types of the biological life cycle are haplontic, diplontic and haplodiplontic life cycle. The brown algae Fucus shows a diplontic life cycle. The haplontic life cycle is seen in most green algae. Some algae such as Ulva, Polysiphonia, Ectocarpus, Kelps have a haplodiplontic life cycle.

What is the introduction of algae?

Algae are an extremely diverse group of organisms that can be found in almost every ecosystem on the planet, and they play an essential role for life on earth. They are little bio-factories that use the process of photosynthesis to create chemical compounds that we can utilize for food, feed, medicine, and even energy.
