Excretion and Egestion Difference

Every organism has to eliminate the waste products produced in the metabolic process that supports life. A plant or an animal has to eliminate those byproducts to avoid the toxicity of the system and carry on surviving in an ecosystem. There are two common terms related to the same concept. Excretion is the process where an organism excretes the byproduct of a metabolic process using the different cellular and organ functions. Egestion, on the other hand, is the term associated with the excretion or elimination of undigested food from the digestive system of an animal. It is also a process of eliminating byproducts of a metabolic process but it involves a digestive system and always happens in the animals. To understand the basic difference between excretion and egestion, you should follow the concept page developed by Vedantu. The expert biology mentors of Vedantu know where the students can get confused. This is where they focus on more and simplify the concept. This simplification helps the students to understand the terminologies and the differences behind them. Make your study easier and convenient by using the concept pages developed to cover the difference between egestion and excretion.


What are Egestion and Excretion? How can you study their differences easily?

To understand the difference between excretion and egestion, first, you have to delve deeper into the basic terminologies related to this topic. An organism maintains different metabolic processes to support its life. In this process, the organism, a plant, or an animal, will have to consume or prepare food to survive. This is the prime concept of life surviving in an ecosystem. During this process, many byproducts are formed inside the organ system of an animal or a plant. This system has to be cleaned up to maintain optimum functionality. This is where the concept of excretion comes into the picture.

A plant will carry on its metabolic process and the excretion process will eliminate the byproducts. T is done by the responsible cell organelles or organs present. For instance, a plant has to get rid of the oxygen produced during the formation of glucose from carbon dioxide. It occurs through the stomata present in the leaves. Similarly, an animal will also get rid of the metabolites and byproducts produced during cellular metabolism. These byproducts are accumulated in the organ responsible for elimination with the help of a circulatory system. Animals urinate using eh kidneys to filter blood and get rid of byproducts.

On the other hand, egestion is a process occurring in the digestive system of an animal where the leftover or undigested food material is excreted via the anus. Some animals excrete using their mouth. It all depends on the physiological structure of the digestive system of every animal. This term is associated with the digestive function of an animal. Hence, egestion can be considered as a sub-process included in excretion. It does not happen in plants as they do not have a digestive system. This is how you can understand and differentiate between excretion and egestion. Now that you have understood the basic concept of the terms, you can easily write down the difference between them, you can also refer to the concept page developed by the experts to cover this section.


Why prefer Vedantu’s concept page to understand Excretion and Egestion?

The question ‘what is the difference between excretion and egestion?’ can only be answered appropriately when you are aware of the definitions and concepts properly. It becomes very necessary to clarify the concept first. The textbook and classroom sessions might not be enough to make it happen. This is where the concept pages of Vedantu can be used as reference material. The expert teachers have compiled the differences between egestion and excretion in such a way that you can easily understand the terms well.

You can easily tackle your doubts related to these terms on your own. There is no need to wait for the class teachers to get your doubts clarified when you can start your preparation beforehand. Find out how easily the experts have explained the differences to distinguish between these two related terminologies in biology. The entire chapter will become clear if you use the concept pages for the rest of the chapter.

Save your time in preparing the chapter and revise quickly at your convenience using these concept pages defining and differentiating egestion and excretion. No need to wait for the chapter to be over when you can continue preparing on your own. You can develop a stronger foundation using these concept pages and can score well in the exams.

FAQ (Frequently Asked Questions)

1. What is the basic difference between Egestion and Excretion?

Answer: Egestion occurs in animals that have a digestive system. It does not occur in plants as they do not have tissues or organs functioning as the digestive system. Byproducts are eliminated using different methods. Hence, animals can egest and excrete whereas plants can only excrete.

2. Which body parts are involved in Egestion?

Answer: Animals generally egest undigested food at the end of the digestive tract. Advanced animals have anus to egest whereas primitive animals such as starfish do it with their mouths.

3. Where does Excretion occurs?

Answer: Excretion occurs in the tissues or organs subjected to eliminate byproducts of the metabolic activities. A leaf excretes oxygen as the byproduct of photosynthesis. Urine is formed and excreted by the urinary system in animals.
