Which one of the following is true for fungi?
Correct answer: B. They are heterotrophs.
- A. They lack a rigid cell wall.
- B. They are heterotrophs.
- C. They lack nuclear membrane.
- D. They are phagotrophs.
Explanation
The true statement for fungi among the options is:"They are heterotrophs."Explanation of each statement:1. "They lack a rigid cell wall": This statement is false. Fungi do have a rigid cell wall, primarily composed of a complex sugar called chitin. The cell wall provides structural support and protection to fungal cells.2. "They lack nuclear membrane": This statement is false. Fungi, like most eukaryotic organisms, have a well-defined nucleus enclosed by a nuclear membrane. This membrane separates the genetic material from the cytoplasm of the cell.3. "They are phagotrophs": This statement is false. Fungi are not phagotrophs. They are saprophytic or parasitic heterotrophs. Fungi obtain nutrients by secreting enzymes that break down organic matter in their environment, and then they absorb the resulting small organic molecules. This process is distinct from phagotrophy, which involves engulfing and digesting whole particles.So, the correct statement is that fungi are heterotrophs because they obtain their nutrients by consuming organic matter in various forms.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
