Depends on your definition of life.

Life is the characteristic state of organisms. Properties common to terrestrial organisms (plants, animals, fungi, protists and bacteria) are that they are cellular, carbon-and-water-based with complex organization, having a metabolism, a capacity to grow, respond to stimuli, reproduce and—through natural selection—adapt.

An entity with the above properties is considered to be organic life. However, not every definition of life considers all of these properties to be essential. For example, the capacity for descent with modification is often taken as the only essential property of life. This definition notably includes viruses, which do not qualify under narrower definitions as they are acellular and do not metabolise. Broader definitions of life may also include theoretical non-carbon-based life and other alternative biology.

While there is no universal agreement on the definition of life, scientists generally accept that the biological manifestation of life exhibits the following phenomena:

1. Organization - Living things are composed of one or more cells, which are the basic units of life.
2. Metabolism - Metabolism produces energy by converting nonliving material into cellular components (synthesis) and decomposing organic matter (catalysis). Living things require energy to maintain internal organization (homeostasis) and to produce the other phenomena associated with life.
3. Growth - Growth results from a higher rate of synthesis than catalysis. A growing organism increases in size in all of its parts, rather than simply accumulating matter. The particular species begins to multiply and expand as the evolution continues to flourish.
4. Adaptation - Adaptation is the accommodation of a living organism to its environment. It is fundamental to the process of evolution and is determined by the organism's heredity as well as the composition of metabolized substances, and external factors present.
5. Response to stimuli - A response can take many forms, from the contraction of a unicellular organism when touched to complex reactions involving all the senses of higher animals. A response is often expressed by motion: the leaves of a plant turning toward the sun or an animal chasing its prey.
6. Reproduction - The division of one cell to form two new cells is reproduction. Usually the term is applied to the production of a new individual (either asexually, from a single parent organism, or sexually, from at least two differing parent organisms), although strictly speaking it also describes the production of new cells in the process of growth.

An egg and an orange don't do all those things.
By the way, I think Fire does qualify, but that is another story.

While eggs that are in the super market are not fertilized and will never develop into a chcken, especially after being cooled, they are alive. Each egg is a single cell. So an ostrich egg is the biggest cell.

An orange is a fruit surrounding the seeds for the new plant and is alive. Even seedless oranges that are reproduced in a different way are alive.

If the egg is natural,you your self can test whether it is a living thing or not when you keep it for incubation it starts developling its organ systems within a few hours inside the calcareous shell(usually fertilized egg) ,if it is not, then it won't (in case of long preservation )otherwise for sure egg is a living thing.orange is also a living thing..After plucking also it has life in it untill it is infested or damaged since many cell cultures can be done only after selecting a particular part from the plant.

Good question. It depend on your definition of "living," which is a tricky concept.

If living things are things that are capable of reproduction:

then -- an unfertilized egg could not be considered living.

An orange is the fruit-part of an orange tree. Certainly the tree is a living thing. The fruit -- maybe. Are your reproductive organs a "living thing?"

Until an egg is fertilized, it is not living. An orange is living when it is growing on a tree.

what. sure are as long as the orange is attached to the tree and the egg is kept warm

Yes ofcourse, but according to me,

An orange is a living thing, untill it is plucked off the tree.

as long as the orange is attached to the tree i guess it is and i dont know about the egg

orange is having life when it is on the tree & similarly egg is also having life till it is in protection from its mother


add my id to ur msngr i have no frenz pleez

of course they are. eggs lead to new animals, oranges lead to new plants.
