What do maggots use for respiration?

When maggots respire they take in a gas from the air and release a different gas. Solution A absorbs the gas released. At the start of the investigation the student records the distance of the water droplet from the bend in the capillary tube.

Do maggots release carbon dioxide?

Aerobic respiration is the process in which glucose and oxygen, through the action of enzymes in mitochondria, produce carbon dioxide, water and lots of energy. In this experiment the use of oxygen in the aerobic respiration of maggots can be seen in that, in a sealed container, the level of oxygen reduces with time.

Do maggots respire aerobically?

Whilst maggots are obviously not human beings, the process or aerobic respiration can be clearly indicated by the reduction in oxygen level (indicated by the oxygen probe) over time in this activity.

How do you investigate the rate of respiration?

Respirometers
We can measure the uptake of oxygen in a given time to work out the rate of respiration. The equipment used is called a respirometer and the effect of changing the temperature on the rate of respiration can be investigated. Respirometers are used to measure the rate of respiration.

How does this experiment show that seeds respire?

Answer: KOH solution absorbs the CO2 released during respiration of seeds, which creates a partial vacuum in the conical flask, causing the rise in the water level of the U-shaped delivery tube. Rise in the level of water shows that CO2 is released during respiration.

Do maggots need oxygen to live?

Larva need oxygen, and fully grown maggots will die unless they can leave the wound to form a pupa, the hard shell in which they grow their adult bodies [sources: BioMonde; NHS].

Why is a respirometer left for 10 minutes?

Why was it left for 10 minutes before the student took any measurements? Acclimatization, to ensure respiration rates have been adjusted to the new temperature.

Where does respiration occur in maggots?

The mitochondria , found in the cell cytoplasm, are where most respiration happens.

Which part of maggot cells does aerobic respiration occur?

The first stages of respiration occur in the cytoplasm of plant and animal cells, but most of the stages of respiration that release energy happen in the mitochondria . Microorganisms do not have mitochondria – they carry out respiration only in the cytoplasm .

Why is soda lime used in respiration experiments?

Soda lime is used to absorb any carbon dioxide produced by the respiring organisms. The gas volume will reduce as oxygen is removed for respiration.

Do worms use the process of respiration?

Earthworms do not have specialized respiratory organs like we do; instead, they take in oxygen and expel carbon dioxide directly through their skin. Oxygen diffuses through the earthworm’s body surface and diffuses inward to the network of capillaries lying just under the body surface.
