Question

Another word for living things is
A) Organ
B) Organism
C) Organelle
D) All of the above

Answer 1

Hint: Living things are the ones which have certain features that are they should have the ability to grow, and they can either prepare their food or they can depend on other organisms for their food, and they should have the ability to reproduce to generate offspring, and along with the living things can sense, and they also respond to the external stimuli, etc.

Complete answer:
Living this has certain features, where they are properly organized or structured, and this has a hierarchy where it can draw on a scale.
Generally in the earth, a small unit of matter is an atom and it has a nucleus in the center, and if 2 or more atoms combined that form the molecules, which mean that they have 2 or more same or different atoms that are joined by bonds, and these molecules form the biomolecules such as proteins, nucleic acids such as DNA, and this structure is surrounded by some fluid and enclosed in a membrane that is called a cell.
The cell is the structural and functional unit of the living thing, and these cells are of different types such as prokaryotic and eukaryotic and this is based on the nucleus and other structures that are present in the living cells that are organelles which include mitochondria, and chloroplast, where this is the part of living things but they are not called as living things so organelle is the wrong option.
Cells are joined together and form the tissues, and the tissues that can perform the similar function are joined together to form the organs, for example, cardiac tissues are joined together to form the heart which called as organ, where they are one of the structures of living things that can perform the individual function, but we cannot call organ as a living thing, so the organ is the wrong option.
Organs together form the organ systems and perform different functions and different organ systems together from the organism, so we call organisms living things.

So, the correct option is B.

Note: The living thing is one which can have different types of cells and they form tissues where these tissues arranged properly to form organs and this organ forms the organ systems and these systems are present not only in animals but also in plants so animals and plants are organisms which are called living things.
