Statement A: Species is the basic unit of classification.Statement B: ...
Basic unit of classification:
- Species is the basic unit of classification in biology.
- It is used to categorize living organisms based on their physical and genetic characteristics.
- It is the lowest level of classification in the hierarchy of biological classification.
Definition of species:
- A species can be defined as a group of organisms that can interbreed and produce viable offspring.
- This means that they share a common gene pool and can exchange genetic material through reproduction.
- However, there are exceptions to this definition, such as asexual organisms or organisms that can interbreed but do not due to geographical or behavioral barriers.
Reproduction and seed formation:
- Reproduction is an important factor in determining the classification of organisms.
- Two plants can be said to belong to the same species if they can reproduce freely with each other and produce viable seeds.
- This is because the ability to interbreed and produce viable offspring is a strong indicator that they share a common gene pool and are therefore closely related.
Conclusion:
- Statement A is true because species is indeed the basic unit of classification in biology.
- Statement B is also true because the ability to reproduce freely and form seeds is an important criterion for determining the classification of organisms at the species level. Therefore, the correct answer is option 'A'.
Statement A: Species is the basic unit of classification.Statement B: ...
Explanation:
Statement A: Species is the basic unit of classification.
- This statement is true. Species is the fundamental unit of classification in biology. It is a group of organisms that share common characteristics and can interbreed to produce fertile offspring.
Statement B: Two plants can be said to belong to the same species if they can reproduce freely with each other and form seeds.
- This statement is also true. The biological species concept defines a species as a group of organisms that can interbreed and produce viable, fertile offspring. If two plants can reproduce freely and produce fertile seeds, they are considered to be of the same species.
Therefore, both statements A and B are true.
