Macroalgae are classified into three major groups: brown algae (Phaeophyceae), green algae (Chlorophyta), and red algae (Rhodophyta). As all of the groups contain chlorophyll granules, their characteristic colors are derived from other pigments.

What is the basis of classification Class 9?

Basis of classification: Organisms with same characteristics are placed in same groups. Presence and absence of nucleus in the cell. Body composed of single cell or group of cells. Autotrophs (producing own food) and heterotrophs (getting food from outside).

What is the basis of classification of algae Brainly?

Explanation: The algae are classified based on pigments. The presence and absence of pigments leads to chlorophyll decides the algae classification. The chlorophyll a and b are present in terms and provides the green colour.

What is algae Class 8?

Algae are simple plant- like organisms which are usually aquatic in nature. They contain a cell wall and chlorophyll and can make their own food by photosynthesis. Algae can be unicellular or multicellular. Some of the common examples are diatoms, chlamydomonas, and seaweed.

What is 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 colonial green algae?

Algae in which cells resembling free-swimming uni cells form groups which may be large and elaborately interconnected as in Volvox, or smaller and relatively simple as in Synura is said to be colonial algae.

Which class belongs to the algae like fungi?

The Phycomycetes fungi possess the characteristics of the algae. Thus, these fungi are also called the algae fungi.

Why are algae green for Class 7?

Algae are green in colour because they contain a green coloured pigment called chlorophyll within their cells.

What is algae Class 5 short answer?

“Alga is a term that describes a large and incredibly diverse group of eukaryotic, photosynthetic lifeforms. These organisms do not share a common ancestor and hence, are not related to each other (polyphyletic).” Multicellular examples of algae include the giant kelp and brown algae.

Algae are chlorophyll-bearing, simple, thalloid, autotrophic and largely aquatic (both fresh water and marine) organisms. They occur in a variety of other habitats: moist stones, soils and wood. Some of them also occur in association with fungi (lichen) and animals (e.g., on sloth bear).
