Exploring the phylum Nematoda, this overview delves into the characteristics of roundworms, their adaptations, and their ecological significance. Roundworms are pseudocoelomates with a complete digestive system and a simple nervous system. They thrive in various habitats and play key roles in nutrient cycling and pest control. The text also highlights the use of C. elegans in research and the importance of studying parasitic nematodes for public health.
Show More
Nematodes have a pseudocoelomic body cavity, a simple nervous system, and longitudinal muscles that facilitate movement
Sexual Reproduction
Nematodes exhibit sexual dimorphism and use specialized structures for sperm transfer
Asexual Reproduction
Some nematodes can reproduce through parthenogenesis or are hermaphroditic
Nematodes have evolved various adaptations to survive in different environments, such as regulating osmotic pressure and protecting against desiccation and mechanical damage
Nematodes play a crucial role in nutrient cycling and pest control
Nematodes can be found in a wide range of habitats, from the ocean to soil
Nematodes are valuable in scientific research, such as the model organism C. elegans, which has contributed to our understanding of development, neurobiology, and disease
Nematodes are classified based on morphology, life cycle, and ecological role
Nematodes have adapted to thrive in nearly every habitat on Earth, with over a million estimated species
00
Nematode body cavity type
Pseudocoelomate - body cavity between digestive tract and body wall, acts as hydrostatic skeleton.
01
Nematode symmetry type
Bilateral symmetry - body is symmetrical on left and right sides.
02
Nematode cuticle composition and function
Cuticle made of collagen and proteins, provides protection and is shed during ecdysis.
