How does Hydra Respirate?

In the hydra, respiration is accomplished via diffusion of molecules of oxygen and carbon dioxide through the skin. The hydra's simple cellular structure ensures that its body's skin layers are thin enough for diffusion to occur.

Does Hydra have respiratory system?

If the Hydra is sliced into many segments then the middle slices will form both a "head" and a "foot". Respiration and excretion occur by diffusion throughout the surface of the epidermis, while larger excreta are discharged through the mouth.

Where are the respiratory gases exchanged in the body of Hydra?

The body of Hydra will be in direct contact with the water. Thus the exchange of gases takes place directly between the cells of hydra and the environment.

How does gas exchange take place in animals?

In animals, gas exchange follows the same general pattern as in plants. Oxygen and carbon dioxide move by diffusion across moist membranes. In simple animals, the exchange occurs directly with the environment. ... Fishes use outward extensions of their body surface called gills for gas exchange.

How does hydra excrete?

The fluid is excreted through a break in the body wall created as a result of a strong contraction when the gut is distended with fluid. A normal hydra, therefore, must remove excess fluid by contracting and expelling it through its mouth.

What type of circulatory system do hydra have?

Hydra have a circulatory system that is similar to jellyfish. They have a fluid filled gastrovascular cavity where nutrients are absorbed.

How does hydra use the Nematocyst?

Nematocysts are produced by nematoblasts, or cnidoblasts, and are used for capturing and paralyzing prey or for defense. ... Each nematocyst contains a coiled, hollow thread that can have barbs or spines and often contains poison.

Which type of respiration is found in amoeba and hydra?

Answer: Respiration in amoeba and hydra occurs by diffusion.

What is the respiratory organ of paramecium?

Unicellular organisms such as amoeba and paramecium respire through their cell membrane. The cell membrane is thin and permeable to gases. They take in oxygen through the entire body surface and give out carbon dioxide. Exchange of gases takes place through the cell membrane by the process of diffusion.

What is the process of gas exchange?

Gas exchange is the process of absorbing inhaled atmospheric oxygen molecules into the bloodstream and offloading carbon dioxide from the bloodstream into the atmosphere. This process is completed in the lungs through the diffusion of gases from areas of high concentration to areas of low concentration.

Which gas is released during respiration?

Animals and plants need oxygen. When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration.

How gas exchange takes place in the respiratory system?

Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

How does exchange of gases take place in fish Class 10?

Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. ... Water taken in continuously through the mouth passes backward between the gill bars and over the gill filaments, where the exchange of gases takes place.

How does exchange of gases occur in organisms like amoeba and fish?

in amoeba, it takes place through the simple process of diffusion, whereas in fishes it takes place mainly in gills.

What is respiration explain the process of gaseous exchange in different animals?

Respiration is the process of releasing energy from food and this takes place inside the cells of the body. The process of respiration involves taking in oxygen (of air) into cells, using it for releasing energy by burning food, and then eliminating the waste products (carbon dioxide and water) from the body.
