what is life process
Answers
Answer:
Life Process
All living organisms have certain characteristics that distinguish them from non-living forms. The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion. All of these processes are interrelated. No part of the body, from the smallest cell to a complete body system, works in isolation. All function together, in fine-tuned balance, for the well being of the individual and to maintain life. Disease such as cancer and death represent a disruption of the balance in these processes.
Answer:
The existence of life on the planet earth is mainly based on certain functions and processes. There are certain basic vital processes, which are essential for an organism to stay healthy and to maintain the proper functioning of the body’s organ systems. They are necessary for survival. These basic essential activities performed by an organism are called life processes.
Types of Life Processes
- Nutrition
- Transportation
- Metabolism
- Respiration
- Reproduction
- Excretion
Nutrition - Nutrition is the process where an entity takes food and utilizes it for energy. It is a pivotal biological process that helps living beings to obtain their energy from various sources.
Transportation- Transportation or transportation system in plants and animals are entirely different. In animals, transportation is carried out through the circulatory system. This system includes the heart, blood, and blood carrying blood vessels.
Metabolism- Metabolism is the chemical process in which different types of chemical reactions are involved in controlling the living state of the cells in an organism. It is broadly classified into catabolism and anabolism.
Catabolism: The metabolic process in which energy is released.
Respiration- Respiration includes the exchange of gases as well as the burning of food. Animals have a well-defined respiratory system for respiration.
Reproduction- The biological process of reproducing their own offspring determines the continuity of species, generation after generation. The basic types of reproduction are sexual and asexual reproduction.
Sexual Reproduction: The process of reproducing their own offspring by the involvement of the two parents.
Asexual Reproduction: The process of reproducing their own offspring by the involvement of a single parent.
Excretion - Elimination of toxic waste substances from the body is called excretion. There are various modes of excretion and it generally differs with the different types of living species.
