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.

Important life processes include nutrition, transportation, metabolism, respiration, reproduction and excretion, which help in the maintenance of living organisms.

The topic of life processes had been discussed in several classes. Life processes Class 10 is a detailed version of different processes carried out by plants and animals.

Types of Life Processes

The different types of life processes are mentioned below:

Life Processes

Important Life Processes

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.

Nutrients are the substances which provide nutrition based on body requirements.

Mode of nutrition varies from one species to another. All green plants exhibit autotrophic nutrition as they synthesize their food by the process of photosynthesis, using light, carbon dioxide and water.

Plants are autographs, they have an autotrophic mode of nutrition. They perform photosynthesis to prepare their own food. Animals are grouped into a heterotrophic mode of nutrition, as they depend on plants for food. All vertebrates, including humans and some unicellular organisms such as amoeba exhibit the holozoic mode of nutrition.

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.

Plants have particular tissues called vascular tissues for the conduction and transportation of materials throughout the plant parts. Vascular tissues include xylem and phloem.

Xylem conducts water and minerals from roots to shoot system while phloem transports prepared food from leaves to other plant parts.

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.

Anabolism: The metabolic process in which energy is stored for further requirements.

Respiration

Respiration includes the exchange of gases as well as the burning of food. Animals have a well-defined respiratory system for respiration.

In the process of respiration, glucose is broken down to extract energy. It is a redox reaction which can take place with or without oxygen and takes place in the mitochondria of the cell and releases energy in the form of ATP.

Respiration is mainly of two types- aerobic respiration and anaerobic 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.
