In defining fungi, which of the following is not a correct statement?

Options

A. Animals are heterotrophic by ingestion while fungi are heterotrophic by absorption
B. Plants have cell walls of cellulose, fungi have cell walls of chitin
C. Energy reserve of fungi is starch while the energy reserve of animals is glycogen
D. Fungi lack flagella at all stages of their life while most protists have a stage that possesses flagella

Explanation

To solve the question regarding which statement about fungi is not correct, we will analyze each option provided:

### Step 1: Analyze Option 1
**Statement:** Animals are heterotrophic by ingestion while fungi are heterotrophic by absorption.
**Analysis:** This statement is correct. Animals consume food and digest it internally (ingestion), while fungi absorb nutrients from their surroundings (absorption).

**Hint:** Consider the different methods of obtaining nutrition in animals and fungi.

### Step 2: Analyze Option 2
**Statement:** Plants have cell walls of cellulose, fungi have cell walls of chitin.
**Analysis:** This statement is also correct. Plant cell walls are primarily made of cellulose, whereas fungal cell walls are composed of chitin.

**Hint:** Recall the composition of cell walls in different kingdoms.

### Step 3: Analyze Option 3
**Statement:** The reserve of fungi is starch while the energy reserve of animals is glycogen.
**Analysis:** This statement is incorrect. The energy reserve in fungi is glycogen, not starch. Starch is the energy reserve in plants.

**Hint:** Think about the storage forms of energy in different organisms.

### Step 4: Analyze Option 4
**Statement:** Fungi lack flagella at all stages of their life while most protists have a stage that possesses flagella.
**Analysis:** This statement is correct. Fungi do not have flagella in any stage of their life cycle, while many protists do have flagellated stages.

**Hint:** Consider the mobility structures present in different groups of organisms.

### Conclusion
After analyzing all the options, we conclude that the statement that is **not correct** is **Option 3**: "The reserve of fungi is starch while the energy reserve of animals is glycogen." The correct information is that fungi store energy as glycogen.

### Final Answer
The statement that is not correct regarding fungi is **Option 3**.
