Which among the following is incorrect about cytotaxonomy and chemotax...
Cytotaxonomy and chemotaxonomy are two different approaches used in the field of taxonomy to classify and categorize organisms. While both methods involve the study of certain characteristics, they differ in terms of the aspects they focus on. Among the given options, option D is incorrect because it states that cytotaxonomy involves only external characteristics, which is not true.
Cytotaxonomy:
- Cytotaxonomy is a branch of taxonomy that is based on the study of the structure, behavior, and function of the cells, particularly the chromosomes, of organisms.
- It involves the examination of various cytological characteristics such as the number of chromosomes, the division of cells during mitosis and meiosis, and the position of the centromere.
- By studying these cytological features, taxonomists can gain insights into the genetic relationships and evolutionary history of different organisms.
Chemotaxonomy:
- Chemotaxonomy, on the other hand, is a method of taxonomy that is based on the chemical composition of organisms, particularly plants.
- It involves the analysis of various chemical constituents such as secondary metabolites, pigments, proteins, nucleic acids, and carbohydrates present in organisms.
- By studying the chemical composition of organisms, taxonomists can identify similarities and differences among different species and use this information to classify and categorize them.
- Chemotaxonomy is particularly useful in cases where morphological characteristics are not sufficient for accurate classification.
Conclusion:
In conclusion, option D is incorrect because cytotaxonomy does not involve only external characteristics. It focuses on the cytological characteristics of organisms, such as the number of chromosomes, cell division, and centromere position. Chemotaxonomy, on the other hand, is based on the chemical composition of organisms. Both approaches play important roles in taxonomy and help in understanding the relationships and classifications of different organisms.
