7 characteristics of non living things?

Answer 1

• The most important characteristic of nonliving things is the absence of protoplasm, the fundamental basis of life. For example, cells are absent in stones or any non living things.
• Due to the absence of protoplasm, no metabolic activities are possible in the nonliving things.
• The structural organization like tissue, organ or system is never found in nonliving things.
• The nonliving things usually do not have any definite form or size of their own. Liquids assume the shape of the container. A liquid like water when heated changes into the gaseous state or can be even frozen into the solid state and thus it has no definite form.
• The movement, if observed, is never automatic but occurs under any other external influence.
• Another Characteristics of Non-living things is that growth occurs by accretion, i.e. by addition of materials from outside. For example a crystal in a solution or a snowball may grow larger in size due to the accumulation of particles of its own unit on the outer surface of the original body.
• The absence of nutrition, excretion, respiration, reproduction, irritability and adaptation are the characteristics of nonliving things.
• The unlimited duration of existence or immortality is a vital characteristic of nonliving things.

Answer 2

1. Lack of metabolism: Non-living things do not require energy for growth or maintenance.
2. Absence of cells: Non-living things do not have cells, the basic unit of living organisms.
3. Lack of response to stimuli: Non-living things do not respond to external stimuli.
4. Inability to reproduce: Non-living things cannot reproduce on their own.
5. No growth or development: Non-living things do not grow or change in structure over time.
6. Lack of homeostasis: Non-living things do not maintain internal stability or balance.
7. No ability to evolve: Non-living things do not undergo genetic changes or adaptations over generations.
