Diffusion
Hydra cells obtain oxygen through diffusion. Gases, including oxygen, are exchanged directly with the surrounding water through the body wall of the hydra. This process allows oxygen to enter the cells and carbon dioxide to exit.
Hydra cells get oxygen through diffusion.
No it is not true
A hydra removes undigested food the same ways it takes in food. A hydra takes in it's food through it's tentacles, so it removes food the same way because it's like a pipe stuck in the ground and there is only one way in and one way out.
They are both producers of food
The green pigment in hydra organisms, called "hydra-chlorophyll," is not produced by the hydra itself but is obtained from the algae that live symbiotically within its cells. This pigment allows for photosynthesis to occur within the hydra and provides energy for the organism.

Hydra are invertebrates. They have no back bone/spinal column.
Step 1, A budd, looking like a bump will appear onto the adult hydra. Step 3, Tectancles that look like long strains will help the new to be hydra get food. Step 4, the new hydra will depart from adult hydra and will start it's journey by it's self. I am sorry I do not know step 2. Step 1, A budd, looking like a bump will appear onto the adult hydra.

Hydra or Hydra
The circulatory system carries food and oxygen to all parts of the body using blood that is circulated by the heart. Red blood cells in the blood carry oxygen to tissues from the lungs, and nutrients from digested food are also transported through the blood to cells in need.
the hydras and sponges do not have a circulatory system.because, the water in which they live brings all the food and oxygen when it enters their bodies. It also carries away all the waste products and carbon dioxide when it moves out.
