Question

Which of the following is not the property of a man-made machine?
A. Perform a complex task
B. Made up of atoms and molecules but not cells
C. Have a level of tissue organization
D. All of the above

Answer 1

Man-made machines are non-living things and hence, cellular organizations that are present in living organisms are absent from machines. The tissue-level organization makes up the biotic components of an ecosystem.

Complete answer: Man-made machines are equipment or tools made by man. Examples are computer, television, refrigerator, etc. Man-made machines are types of equipment that perform tasks as per the order as they cannot think and read emotions. These machines are highly complex and perform difficult tasks, for example, computers can calculate very large equations in seconds. They are made up of the elements which are composed of atoms and not cells. Cells are living things and they organize themselves to form tissues. As machines don’t have cells, hence the tissue organization is absent in man-made machines.
Hence, the correct answer is option C.

Additional information: Cell is the structural and functional unit of life. It is the smallest unit of any living organism. Many cells combine and form tissue. Many tissues combine and form an organ. Many organs form the organ system and the organ system gives rise to a new organism. Hence, the level of tissue organization can’t be the property of a man-made machine.

Note: Like cells, machines also require power to perform certain tasks. The power source can be thermal, electrical, chemical, solar etc. Machines are very useful in day to day life as it reduces labour, time, etc. Everything from a telephone to a fan is an example of machines.
