| 1. What are the main characteristics of Ctenophora? |  |
Ans.Ctenophora, commonly known as comb jellies, are marine invertebrates characterized by their gelatinous bodies and distinctive rows of cilia known as comb plates.

| 2. How do Platyhelminthes differ from Aschelminthes? | |
Ans.Platyhelminthes, or flatworms, are characterized by their flattened bodies and lack of a coelom, while Aschelminthes (now often referred to as a paraphyletic group including various pseudocoelomates) possess a pseudocoelom. Additionally, Platyhelminthes include classes such as Turbellaria and Cestoda, whereas Aschelminthes includes groups like Rotifera and Nematoda.
| 3. What is the significance of Ctenophora in marine ecosystems? | |

| 4. What are the reproductive strategies observed in Platyhelminthes? | |
Ans.Plstyhelminthes exhibit diverse reproductive strategies, including both sexual and asexual reproduction. Many flatworms are hermaphroditic, possessing both male and female reproductive organs, while some can reproduce asexually through fragmentation, allowing them to regenerate lost body parts.
| 5. How do Aschelminthes contribute to soil health? | |
Ans.Aschelminthes, particularly nematodes, play an essential role in soil health by participating in nutrient cycling. They help decompose organic matter, regulate microbial populations, and enhance soil structure, which contributes to plant growth and ecosystem sustainability.
