  • Chrysophyta (Golden-brown algae and Diatoms)
  • Pyrrophyta (Fire algae)
  • Chlorophyta (Green algae)
  • Rhodophyta (Red algae)
  • Paeophyta (Brown algae)

What is basis of classification?

The basis of classification are as follows: • Cell structure. • Mode and source of nutrition. • Body organisation. Classification makes the study of a wide variety of organisms easier.

What is importance of algae?

In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration.

What is the basis of classification of algae write down the various characteristic features of Chlorophyceae?

Question 1: What is the basis of classification of algae? Answer: The presence or absence of pigments is the main basis of classification of algae. Chlorophyceae: Chlorophyll a and b are present in them and impart green colour. Chlorophyceae are also called ‘blue-green algae’.

What are the classifications and the general 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.

Who proposed classification of algae?

It was Leeuwenhoek, 1674 who first observed unicellular algae under the microscope. Since Linnaeus (1753) published “Species Plantarum” and classified algae. Many algologists (phycologists) have proposed different classification systems based on various algal characters.

Who discovered the classification of 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 importance of algae?

In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration.

What is the scientific name of algae?

The algae are further grouped into various phyla and the suffix –phyta is used in the classification of algae: Euglenophyta (euglenids), Chrysophyta (diatoms), Pyrrophyta (dinoflagellates), Chlorophyta (green algae), Phaeophyta (brown algae), and Rhodophyta (red algae).

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 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.
