Biochemical resemblances are used in the identification of :–

Options

A. Protistan species
B. Moneran species
C. Fungal species
D. Higher plants

Answer

**Step-by-Step Solution:**

1. **Understanding Biochemical Resemblances**: Biochemical resemblances refer to the similarities in the biochemical composition of organisms, which can include proteins, nucleic acids, and metabolic pathways. These similarities can be used to identify and classify different species.

2. **Identifying the Groups**: The question asks about the identification of specific groups of organisms using biochemical resemblances. The options provided are:
- Protistian species
- Moneran species
- Fungal species
- Higher plants

3. **Analyzing the Options**:
- **Protistian Species**: While biochemical methods can be used, they are not the primary method for identification.
- **Moneran Species**: This group includes prokaryotes (bacteria and archaea). Biochemical methods, such as studying the 16S ribosomal RNA and metabolic pathways, are crucial for identifying and classifying these organisms.
- **Fungal Species**: Biochemical methods can aid in identification, but morphological features are also significant.
- **Higher Plants**: Identification is primarily based on morphological characteristics rather than biochemical resemblances.

4. **Conclusion**: Given that Moneran species (prokaryotes) rely heavily on biochemical characteristics for their identification due to their simple structure and lack of well-developed morphological features, the correct answer is Moneran species.

**Final Answer**: Moneran species.
