In Spirogyra, asexual reproduction takes place by fragmentation. A) True B) False
Hint:The process in which an organism split to form into many fragments. Fragmentation is the state or process of breaking down an organism into small fragments or pieces.
Complete answer: The process of asexual reproduction in Spirogyra is known as fragmentation, where the body of spirogyra when matures will get break into many smaller pieces or fragments due to strong water current. These different pieces will later grow into new individuals.
Additional Information: -Spirogyra is a genus of green algae. -They are commonly found in freshwater habitats such as ponds, lakes, etc. They are commonly known as water silk or pond silk. -Spirogyra is valued for human consumption and is an important source of natural bioactive compounds for antibiotics, antiviral, antioxidant, and anti-inflammatory. -The filament of spirogyra is unbranched with the spiral or helical arrangement of the chloroplast. -Fragmentation is the process of vegetative reproduction in spirogyra. -The filament of spirogyra breaks into different fragments due to the presence of mechanical injuries. -Each of the fragments of the filament will grow into a full-grown new individual which is similar to their parents. -It is advantageous as any part can be taken as a fragment to develop a new individual.
So, the correct answer is True.
Note: It should be remembered that the test cross is a type of back cross where F1 generation is crossed with F0 generation. -Pleiotropy - It is the name given to a gene when a single gene can regulate or influence multiple phenotypic characters. -Polygenic Inheritance- When a single phenotypic character is controlled by two or more genes, it is known as polygenic inheritance.
