Answers
1. Amoeba respires through their cell membrane also know as plasma membrane.
It gets oxygen gas dissolved in its surrounding water through its plasma membrane by the process of diffusion.
2. Earthworms has no particular respiratory organ.
Gases are exchanged through moist skin and cappilaries, where oxygen is picked up by the haemoglobin present in the blood plasma and carbon dioxide is released.
3. The respiratory system of cockroach is known as tracheae.
It is a dense networked array of air tubes in the internal system.
Air enters through the tracheae, spiracle acts as a muscular valves leading to the internal respiratory system.
4. Respiration in plants involve using the sugar produced in photosynthesis and oxygen for energy.
Its respiratory system includes stomata.
5. Aquatic animals has gills which take up oxygen diffused in water and give up carbon dioxide through bloodstreams.
6. Birds do not have diaphgram instead air is moved in and out through respiratory system through pressure changes in air sacs.
