25. What are the basic structures of all living organisms? (1 point)
[Choice A] atoms
[Choice B] organelles
[Choice C] quarks
[Choice D] cells
[Choice D] cells
The correct answer is [Choice D] cells. Cells are the basic structures of all living organisms.
The correct answer is [Choice D] cells.
All living organisms are made up of cells. Cells are the basic units of life and are considered the building blocks of all living things. They are the smallest structural and functional units that can carry out the essential processes necessary for life.
To arrive at this answer, it is helpful to have a basic understanding of biology and the organization of living organisms. When considering the various options provided, we can eliminate choices like [Choice A] atoms and [Choice C] quarks, as they are not specific to living organisms and can be found in non-living matter as well. This leaves us with [Choice B] organelles and [Choice D] cells.
While organelles are essential components found within cells, they are not found in all living organisms. Some organisms, like bacteria, do not have membrane-bound organelles but are still considered living. Therefore, the correct choice is [Choice D] cells, which are present in all living organisms and provide the necessary structure and function.
