Tracheoles lack rings of chitin because they are the finest branches of the tracheal system in insects, designed for gas exchange rather than structural support. Their small diameter and extensive branching allow for efficient diffusion of oxygen directly to tissues. The absence of chitin rings enables greater flexibility and reduces resistance to airflow, facilitating effective respiration at the cellular level. This adaptation is crucial for meeting the high metabolic demands of active insects.
What else can I help you with?
What is the process that allows oxygen to pass from the tracheoles to the body cells?
Oxygen diffuses from the tracheoles into the body cells through a process called passive diffusion. This process relies on a concentration gradient, where oxygen moves from an area of high concentration in the tracheoles to an area of low concentration in the body cells.
What is a complex carbohydrate found in the cell walls of fungi and in insect exoskeletons called?
Chitin.
Does tree moss contain chitin?
No, tree moss does not contain chitin. Chitin is a component of the exoskeleton of insects, arachnids, and crustaceans. Tree moss belongs to the plant kingdom and does not produce chitin in its structure.
The walls of fungi are reinforced with?
chitin, a structural polymer similar to the one found in the exoskeletons of insects, are reinforced with beta-glucans and chitin.
What is the other name for chitin?
The other name for chitin is poly-N-acetylglucosamine.
Is chitin inorganic?
No, chitin is a natural biopolymer classified as an organic compound. It is a structural polysaccharide found in the exoskeletons of arthropods, such as insects and crustaceans, as well as in the cell walls of fungi.
What is the process that allows oxygen to pass from the tracheoles to the body cells?
Oxygen diffuses from the tracheoles into the body cells through a process called passive diffusion. This process relies on a concentration gradient, where oxygen moves from an area of high concentration in the tracheoles to an area of low concentration in the body cells.
Why do piston rings get damaged?
pistons rings are damages, because1. Lack of lubrication2. Engine over heating
Which vertebrates lack exoskeleton?
arthropods and mostly molluscas have exoskileton made up of chitin and calcium carbonate respectively
What are 5 characteristics of fungi?
eukaryotic, heterotrophic, lack of tissue differentiation, have cell wall of chitin or other polysaccharides, propagate by spores
How are fungal cells differe from plant cells?
Fungal cells have cell walls made up of chitin. They lack chloroplasts and heterotrohic
The bronchioles lack the support of what?
Cartilage rings that are found in trachea
What is the name of the polysaccharide that is found in the cell walls of fungi and the exoskeletons of arthropods?
Chitin is the polysaccharide found in the cell walls of fungi and the exoskeletons of arthropods.
Do fish scales contain chitin?
Chitin
Is chitin a heteropolysaccharide?
Yes, chitin is a heteropolysaccharide.
From what language do you get the word chitin?
"chitin" comes from the French word "chitine", meaning the same substance, chitin.
What is a complex carbohydrate found in the cell walls of fungi and in insect exoskeletons called?
Chitin.
