Question

Which one of the following is a form class of red algae?
A. Deuteromycetes
B. Basidiomycetes
C. Rhodophyceae
D. Euglenophyceae

Answer 1

Hint:- Algae are defined as the simple, non-flowering, and generally water plant of a vast group that comprises the seaweeds and various single-celled forms. Algae can perform photosynthesis because chlorophyll is present but they lack true stems, roots, leaves, and vascular tissue (xylem and phloem). They can be unicellular or multicellular.

Complete Answer:-
Deuteromycetes is a type of anamorphic fungi commonly known as molds. They do not undergo sexual reproduction in their life cycle and thus reproduce only by producing spores (conidia or Odia) or by budding. It is known as imperfect fungi because it does not fit into the normally organized taxonomic classifications of fungi. Basidiomycetes are the type of fungal spores that are produced externally, at the end of specialized cells known as basidia. Generally, there are about four spores per basidium, although this varies from one to many, relying on the species.
Rhodophyceae is a type of red algae because of the presence of a water-soluble pigment known as phycoerythrin, this pigment masks the chlorophyll a. It may be unicellular or multicellular. Euglenophyta is a unicellular, naked, and flagellate motile species which is usually present in fresh-water. It is green in colour because of the presence of chlorophyll localized in the chromophore.
Thus, the right option is C.

Note:- Rhodophyceae is a large group of algae comprising about 5250 species. More than 98% of species of red algae are marine while only 20% are freshwater species. They are non-motile because of the absence of flagella. Members of Rhodophyceae exhibit a large difference in the number of nuclei inside the cells. Reserve food of red algae is Floridian starch.
