KINGDOM PROTISTA

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Early classification systems placed plants and fungi in the same kingdom. What question would have led scientists to separate plants and fungi into two distinct kingdoms?
A
Does the organism use sunlight tomake food?
B
Do the cells contain a nucleus?
C
Does the organism many cells?
D
Does the organism grow from the ground?
Explanation: 

Detailed explanation-1: -Based on observations of mushrooms, early taxonomists determined that fungi are immobile (fungi are not immobile) and they have rigid cell walls that support them. These characteristics were sufficient for early scientists to determine that fungi are not animals and to lump them with plants.

Detailed explanation-2: -A unique feature of fungi is that they contain chitin in their cell wall. They were previously filed under plants but since they lack chlorophyll pigments and have different structural features compared to plants, they have been named a separate kingdom.

Detailed explanation-3: -Solution : In two-Kingdom classification system bacteria, blue-green algae and fungi were placed under plants because all these organisms had cell wall in their cells.

Detailed explanation-4: -They are unable to produce their organic food through the process of photosynthesis. They are heterotrophic, and depend on the food produced by others. They feed on the dead and decaying remains of living organisms. Due to the absence of photosynthetic pigment chlorophyll, fungi are not included in the kingdom plantae.
