Which of the following is not a character related to Red Algae?

Options

A. Sexual reproduction is oogamous.
B. they occur in both well lighted areas and great depths of oceans.
C. The food stored in them in cynophycean, starch, very similar to amylopectin and glycogen.
D. They reproduce asexually by non motile spores.

Answer

To determine which of the following is not a character related to Red Algae, we will analyze each statement provided.

1. **Statement 1:** "Sexual reproduction is oogamous."
- **Analysis:** In red algae (Rhodophyceae), sexual reproduction is indeed oogamous. This means that the male gamete is motile and smaller, while the female gamete is larger and non-motile. Therefore, this statement is correct.

2. **Statement 2:** "They occur in both well-lighted areas and great depths of ocean."
- **Analysis:** Red algae can thrive in various environments, including well-lighted areas like shallow waters and also at great depths in the ocean. This statement is also correct.

3. **Statement 3:** "The food stored in red algae is cyanophycine, starch very similar to amylopectin and glycogen."
- **Analysis:** This statement is incorrect. The food stored in red algae is not cyanophycine; rather, it is Floridian starch, which has a structure similar to amylopectin and glycogen. Cyanophycine is associated with cyanobacteria, not red algae.

4. **Statement 4:** "They reproduce asexually by non-motile spores."
- **Analysis:** This statement is correct. Red algae reproduce asexually using non-motile spores.

**Conclusion:** The statement that is not a character related to red algae is **Statement 3**.
