Question 2: Write the classification of living organisms according to R.H Whittaker.
Answer:
R.H. Whittaker classified living organisms into 5 kingdoms based on their cell structure, complexity, reproduction, mode of nutrition, and phylogenetic relationships.Five kingdoms are:

- Protista
- Fungi
- Animalia
- Plantae

Answer:
They are called algal fungi, and they are found in aquatic habitats, damp places, and on decaying wood in moist or as an obligate parasite on plants. Common examples are- Rhizopus, Mucor, and Albugo.

Phycomycetes
Biological classification can be defined as the method used to categorize and group living organisms based on their features and functions, also known as taxonomy. The first biological classification is done by Aristotle, who classified living organisms based on morphological characteristics. According to the classification of Aristotle, organisms can be classified as Organisms that have red blood cells and Organisms that don’t have red blood cells. After that, Carolus introduced the system of kingdoms. According to him, there are two kingdoms, Animalia and Plantae. But still, there are some organisms that didn’t get any categorization from this classification. Then R.H. Whittaker classified organisms. R.H. Whittaker classified living organisms into 5 kingdoms based on their cell structure, complexity, reproduction, mode of nutrition, and phylogenetic relationships. The five kingdoms are Monera, Protista, Fungi, Animalia, and Plantae.
