Describe how an organism is made start from atom ?

An organism is made up of different levels of organization, starting from the simplest unit of matter, the atom. Atoms are the building blocks of molecules, which are the basis for the formation of cells.

Atoms combine to form molecules through chemical bonding. For example, atoms of carbon, hydrogen, and oxygen can bond together to form a molecule of glucose, an important energy source for organisms.

Molecules then come together and interact to form cells, which are the basic structural and functional units of life. Cells are composed of various molecules, including proteins, lipids, carbohydrates, and nucleic acids. These molecules work together to carry out the essential processes necessary for the cell's survival and function.

Multiple cells can then join together to form tissues, such as muscle, nerve, or connective tissues. Different types of tissues work collectively to carry out specific functions in an organism.

Tissues combine further to form organs, which are specialized structures with specific functions within the body. For example, the heart is an organ responsible for pumping blood, and the lungs are organs involved in respiration.

Several organs work together as organ systems to perform specific physiological functions necessary for an organism's survival. Examples of organ systems include the circulatory system, respiratory system, digestive system, and nervous system.

Lastly, all the organ systems interact and form an organism, a complete living being capable of carrying out all the necessary life processes to survive, grow, and reproduce. This organization from atoms to organisms represents the hierarchical nature of life's structure and complexity.

Sure! Here is a step-by-step process of how an organism is made starting from atoms:

1. Atoms: All living organisms are made up of atoms, which are the smallest units of matter. These atoms combine to form molecules, which are the building blocks of life.

2. Elements: Atoms can combine in different ways to form elements. Elements are substances made up of only one type of atom. Examples of elements found in living organisms include carbon, hydrogen, oxygen, nitrogen, and phosphorus.

3. Biomolecules: Elements combine to form biomolecules, which are essential for life. There are four main types of biomolecules found in organisms:

a. Proteins: Composed of amino acids, proteins perform various functions in the body, such as enzyme catalysts, structural components, and transportation molecules.

b. Carbohydrates: Made up of sugar molecules, carbohydrates are a major energy source for organisms. They also play important roles in cellular structure and cell recognition.

c. Lipids: Lipids, such as fats and phospholipids, are essential for energy storage, insulation, and maintaining the structure of cell membranes.

d. Nucleic acids: DNA and RNA are nucleic acids that store and transmit genetic information. They are involved in the synthesis of proteins and carry the instructions for the development and functioning of organisms.

4. Cells: Biomolecules combine to form cells, which are the basic structural and functional units of all living organisms. Cells can be either prokaryotic (lacking a true nucleus) or eukaryotic (containing a true nucleus). They have various organelles that perform specific functions within the cell.

5. Tissues: Cells of similar types combine to form tissues. Different types of tissues, such as epithelial, connective, muscular, and nervous tissues, have specific functions and work together to perform different tasks in the organism.

6. Organs: Different tissues work together to form organs. Organs have specific functions and are composed of two or more different types of tissues. Examples of organs include the heart, lungs, liver, and brain.

7. Organ Systems: Organs with related functions combine to form organ systems. Organ systems work together to carry out specific functions necessary for the survival and functioning of the organism. Examples of organ systems include the circulatory system, respiratory system, digestive system, and nervous system.

8. Organism: All the organ systems in an organism work together to maintain the overall life functions. This integration of organ systems gives rise to a fully functional organism capable of growth, reproduction, response to stimuli, and adaptation to the environment.

In summary, an organism is made starting from atoms, which combine to form elements, biomolecules, cells, tissues, organs, organ systems, and finally, a complete living organism.
