Question

According to Tippo, BGA is included in
A. Chrysophyta
B. Pyrrophyta
C. Chlorophyta
D. Cyanophyta

Answer 1

Hint: Oswald Tippo was an American botanist. He proposed a modern classification of the plant kingdom. Blue-green algae are prokaryotic organisms. These are the primitive forms of organisms which lack membrane-bound organelles. They lack a well-developed nucleus and other developed cellular structures. Blue-green algae are usually green but turn bluish during the death of scums. Some species of blue-green algae are capable of forming toxins.

Complete answer:
Tippo in the University of Illinois in 1942, categorized plant kingdom into sub-kingdoms based on the presence and absence of embryo, they are Thallophyta and Embryophyta.
The subkingdom thallophyta was divided into ten phyla they are Cyanophyta(Blue-green algae), Euglenophyta(Grass green algae), Chrysophyta(Yellow-green algae), Chlorophyta(Green algae), Pyrrophyta(Golden Brown Algae), Phaeophyta(Brown algae), Rhodophyta(Red algae), Schizomycophyta(Bacteria), Myxomycophyta(Slime Molds), Eumycophyta(True fungi).
Cyanophyta consist of both free-living photosynthetic bacteria and the endosymbiotic plastids.
Cyanobacteria are known as blue-green algae because they are capable of performing photosynthesis.
It is used as a nutrient supplement. Also used in many medicinal products.
Chrysophyta includes yellow-green algae.
Pyrrophyta includes brown algae.
Chlorophyta includes green algae.
So, the correct answer is “Option D”.

Additional Information:
Thallophyta is a thalloid plant body without a definite alternation of generation.
Embryophyta have organ level differentiation of the plant body with distinct alternation of sporophyte and gametophyte generations.
Blue-green algae have unpleasant taste and odour.
Blue-green algae help in losing weight and boosting the immune system.
BGA can deplete the oxygen content of water bodies.
