Hydra expels waste and undigested food through its mouth, which serves a dual purpose as both the entry point for food and the exit for waste. After capturing prey, the hydra digests it in its gastrovascular cavity, and any indigestible remnants are pushed back out through the same opening. This simple process is efficient for their small, tubular body structure.
To remove undigested food and bodily waste from their system
Waste is removed through a designated opening
what is the difference between undigested food and metabolic waste
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.
The elimination
undigested food
Undigested food waste is excreted through the anus.
The vacuole is responsible for storing water, undigested food, and waste products in a plant cell. In animal cells, waste products are stored in vesicles or lysosomes.
The volume of the undigested food decreases as it passes through the large intestine. As the colon absorbs excess water from undigested food waste, the volume of that waste decreases.
Faeces is made from undigested waste food in your body, mucus and toxins
The colon absorbs water from undigested food waste so that the waste can be excreted as feces.
In amoebas, undigested food is egested through a process called exocytosis, where waste materials are expelled from the cell. This occurs at the cell membrane, which surrounds the undigested food particles, forming a vesicle that merges with the membrane to release the waste into the surrounding environment. Amoebas do not have specialized structures for egestion, as they are single-celled organisms.
