  • Phaeophyceae – Also called as brown algae, they are predominantly marine. …
  • Rhodophyceae – They are the red algae because of the presence of the red pigment, r-phycoerythrin.

What is the basis of classification of algae in biology?

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’.

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 the basis of classification of algae Brainly?

Expert-verified answer

The presence or absence of pigments is the main basis of classification of algae.

What is basis of classification?

The basis for the biological classification scheme is similarity of morphology (shape) and phylogeny (evolutionary history). In addition, the processes that led to these similarities are also used in biological classification.

What is the basic unit of classification?

Species
Species constitute a group of phenotypically similar organisms with common ancestry that can interbreed freely to produce fertile progeny and hence, is considered the basic unit of classification.

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.

What is importance of classification?

Classification is needed for convenient study of living organisms. It is necessary for knowing the different varieties of organisms. It helps in the correct identification of various organisms. It helps to know the origin and evolution of organisms.

What are the basic characteristics of classification?

The more basic characteristic for classifying organisms is the kind of cells they are made of because different organisms may share same habitat but may have entirely different form and structure. So, the place where they live cannot be a basis of classification.

What are the uses of classification?

Classifications are the most frequently used—and most useful—prediction types. Classifications are predictions that separate data into groups. Binary Classification produces “yes-no” or “in-out” answers when there are only two choices.

What are the five importance of classification?

(i) It helps in studying wide variety of living organisms. (ii) It provides a clear picture of all life forms before us. (iii) It helps in understanding the inter-relationship among different groups of organisms. (iv) It provides a base for the development of other biological sciences.

What are the five objectives of classification?

Five objectives of classification are:- (i)The creation of a method for quickly recognising a species, whether it is known or unknown. (ii)The description of various species. (iii)Recognition of different species. (iv)To distribute qualities at different levels of a hierarchy.

What is classification process?

Classification is the process of ensuring that unclassified images are included in their class within certain categories [1]. Image classification is a problem of computer vision that deals with a lot of basic information from fields such as healthcare, agriculture, meteorology and safety.

What is called classification?

Definition of classification

1 : the act or process of classifying. 2a : systematic arrangement in groups or categories according to established criteria specifically : taxonomy.
