In Whittaker's phylogenetic classification, slime moulds belong
to

Options

A. (a) Fungi
B. (b) Protista
C. (c) Monera
D. (d) Animalia

Answer

To determine where slime molds belong in Whittaker's phylogenetic classification, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Whittaker's Classification**: Whittaker classified living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. Each kingdom is based on specific criteria such as cellular organization, mode of nutrition, and reproductive methods.

2. **Identify Characteristics of Slime Molds**: Slime molds are unique organisms that exhibit characteristics of both fungi and protists. They are primarily unicellular eukaryotes, meaning they have a defined nucleus and are single-celled.

3. **Determine the Appropriate Kingdom**: Since slime molds are unicellular and eukaryotic, they fit the definition of organisms in the Protista kingdom. Although they share some characteristics with fungi, they do not form true multicellular structures like fungi do.

4. **Select the Correct Answer**: Based on the classification and characteristics, slime molds belong to the kingdom Protista. Therefore, the correct answer is B. Protista.

### Final Answer:
Slime molds belong to **B. Protista** in Whittaker's phylogenetic classification.
