Ctenophores exhibit

Options

A. Bioluminescence
B. Sessile nature
C. Paedogenesis
D. Both (1) & (3)

Answer

To solve the question "Ctenophores exhibit," we will analyze the options provided and determine which properties are characteristic of Ctenophores.

### Step-by-Step Solution:

1. **Understanding Ctenophores**:
- Ctenophores, also known as comb jellies, are marine invertebrates belonging to the phylum Ctenophora. They are known for their unique characteristics.

2. **Option Analysis**:
- **Option 1: Bioluminescence**:
- Ctenophores are known to exhibit bioluminescence, which is the ability to produce and emit light. This is a common trait among many Ctenophore species, allowing them to glow in the dark.
- **Conclusion**: This option is correct.

- **Option 2: Fissile Nature**:
- Fissile nature refers to the ability to reproduce by fission, which is a form of asexual reproduction. Ctenophores do not reproduce by fission; they are free-moving and motile organisms.
- **Conclusion**: This option is incorrect.

- **Option 3: Pedogenesis**:
- Pedogenesis refers to the process where sexually mature larvae reproduce without fertilization. Some Ctenophores can reproduce through pedogenesis, which is a unique reproductive strategy.
- **Conclusion**: This option is correct.

3. **Final Answer**:
- Based on the analysis, Ctenophores exhibit both bioluminescence and pedogenesis. Therefore, the correct answer is that Ctenophores exhibit properties of bioluminescence (Option 1) and pedogenesis (Option 3).

### Summary of the Answer:
Ctenophores exhibit bioluminescence and pedogenesis.
