37) Various life processes indicate that human beings are alive. Elaborate the following life processes in your own words (in 30-50 words each). 37.1) Organisation: 37.2) Processes of metabolism: 37.3) Nutrition: 37.4) Biological maturation: 37.5) Inheritance: 37.6) Ageing:

Expert Solution

ORGANISATION: Human body comprises of five levels of organisation . Cells,Tissues,Organs,Organsystems and Organism. Each level has its own job.

Cells are the building blocks of life forming the first level of organisation.There are about trillions of cells in body. Eg. stem cells, nerve cells, blood cells.
Tissues are formed by group of similar cells. Tissues act together to perform specific function. Eg. skeletal ,blood, connective, nervous tissues
Group of two or more tissues unite to perform a specific function forming an organ. Eg. brain, heart
Organsystems are formed by group of organs . There are about 11 organ systems in the body . Eg. Heart and blood vessels form cardiovascular system.
All organ systems work together to keep the body functioning and carry out the life process in an organism.

Process of metabolism:

Metabolism is the chemical reaction occuring within each cell in an organism
Catabolism and anabolism are two processes in metabolism
Energy is synthesized which is essential for a living cell using metabolism

Nutrition:

Nutrition is intake of nutrients and food needed to produce energy for the living organisms
Nutrition is essential for the growth and development of an organism

Biological maturation:

The tissues, organs and organ systems attains maturity at different rates in different periods of growth and development of an organism .

Inheritance:

It is the process of passing genetic characteristics from parents to offspring.
