Explaining the Truth of Statement A and Statement B
Statement A: Species is the basic unit of classification.
Species is the basic unit of classification, and it is the group of living organisms that share a common gene pool and can interbreed to produce viable offspring. The concept of species is important in taxonomy and is used to group and classify organisms based on their physical, genetic, and ecological characteristics.
Statement B: Two plants can be said to belong to the same species if they can reproduce freely with each other and form seeds.
The biological species concept defines a species as a group of organisms that can interbreed with each other to produce viable offspring. Therefore, two plants can be said to belong to the same species if they can reproduce freely with each other and form viable offspring that can grow into new plants.
Explanation of Answer
Both statements A and B are true. Species is the basic unit of classification, and it is defined as a group of living organisms that share a common gene pool and can interbreed to produce viable offspring. The biological species concept defines a species as a group of organisms that can interbreed with each other to produce viable offspring. Therefore, two plants can be said to belong to the same species if they can reproduce freely with each other and form viable offspring that can grow into new plants.
In conclusion, the concept of species is important in taxonomy, and it is used to group and classify organisms based on their physical, genetic, and ecological characteristics. The biological species concept defines a species as a group of organisms that can interbreed with each other to produce viable offspring, and two plants can be said to belong to the same species if they can reproduce freely with each other and form viable offspring that can grow into new plants. Hence, both statements A and B are true.
Statement A: Species is the basic unit of classification.Statement B: ...
Both the statements are correct. Closely linked organisms belong to the same species and they can interbreed among themselves to produce fertile progenies.
Hence, the Correct Answer is D
