what is life process Related:  Practice Questions (Part - 1) - Life Process?

Answer

*The processes which together perform the maintenance of  job to keep living things alive are known as life processes.

Answer

All the living organisms perform basic functions in order to survive on earth. These basic functions performed by living organisms to maintain their life are called LIFE PROCESS.

Answer

The process which together perform the maintenance function of living organism are called life process

Answer

Life processes are the essential activities that living organisms perform in order to maintain their existence and carry out their functions. These processes are crucial for the survival, growth, and reproduction of organisms. They involve various functions such as nutrition, respiration, transportation, excretion, and reproduction.

- Nutrition:
Nutrition is the process by which organisms obtain and utilize food for energy, growth, and repair. It involves the intake of food, its digestion, absorption of nutrients, and elimination of waste. There are two types of nutrition: autotrophic and heterotrophic. Autotrophic nutrition is exhibited by plants and some bacteria, where they synthesize their own food using sunlight through the process of photosynthesis. Heterotrophic nutrition is seen in animals, fungi, and most bacteria, where they obtain food by consuming other organisms.

- Respiration:
Respiration is the process through which organisms obtain energy from food. It involves the exchange of gases, mainly oxygen and carbon dioxide, between an organism and its environment. Respiration can be aerobic (with the use of oxygen) or anaerobic (without the use of oxygen). In aerobic respiration, glucose is broken down to release energy in the presence of oxygen, while in anaerobic respiration, glucose is partially broken down in the absence of oxygen, resulting in the production of lactic acid or ethanol.

- Transportation:
Transportation is the process of moving substances within an organism. It involves the circulation of materials such as nutrients, gases, hormones, and waste products throughout the body. In multicellular organisms, transportation occurs through specialized systems like the circulatory system in animals and the vascular system in plants.

- Excretion:
Excretion is the process of removing waste products from the body. It involves the elimination of metabolic waste products such as carbon dioxide, urea, and excess water. In animals, excretion occurs mainly through the urinary system, while in plants, it occurs through stomata, lenticels, and the root system.

- Reproduction:
Reproduction is the process by which organisms produce offspring of their own kind. It ensures the continuation of species. There are two types of reproduction: asexual and sexual. Asexual reproduction involves the production of offspring from a single parent without the involvement of gametes. It leads to the formation of genetically identical offspring. Sexual reproduction involves the fusion of male and female gametes, resulting in the production of genetically diverse offspring.

In conclusion, life processes are the fundamental activities that living organisms carry out to maintain their survival and ensure the continuation of their species. These processes include nutrition, respiration, transportation, excretion, and reproduction. Each process plays a vital role in the overall functioning of an organism.
