Are living organisms made up of living cells?

Not necessarily, just like our most superficial layer of epidermal cells is dead cells, and there are calluses on our hands.

Dead meat is usually dead cells, and some microorganisms are so low that they don't even have the basic structure of cells.

No, in general, a living organism must have life, and the smallest unit that makes up a living organism is the cell. But the definition in biology books is: all living things are made up of cells (except viruses).

So a living virus is a living organism, but it is not made up of living cells because viruses do not have a cellular structure.

The words of the organism ... Viruses are contained within the confines of living things. Viruses do not have a cellular structure, and certainly not living cells. Live or die ...

I understand ...

If you look at the upstairs, it seems that the upstairs understands that all the cells of an individual organism are living cells.

I understand all species to mean all species within the scope of living things.

The landlord can combine it for reference.

Adversity.. There is also the second floor said that the red blood cells die after oxygen supply... What is the meaning?

Mature red blood cells do not have a nucleus. I don't think there's any organelles. Well, no. By definition, it can't multiply or anything. I don't think it's a living cell. In other words, red blood cells are not living cells after they mature (before?). I don't know).

Adversity.. Then, what does it mean to be finished?。。 It's not a one-time thing.

Personal understanding、、、 there is something wrong with it, please point it out.

Wrong. For example, ductal cells (transporting water and inorganic salts) and wood fibroblasts (supporting role) in plants are dead cells, but they are part of a living organism.

If it's a non-cellular organism virus, it's even more wrong.

There are both live cells, dead cells, and dying cells.

A person's red blood cells die after they are supplied with oxygen.

No. Not all living things are made up of cells.

It can only be said thatIn addition to virusesAll living things are made up of cells.

Viruses are also living organisms, but viruses do not have a cellular structure.

It is not a cellular organism.

Living cells: have a cellular structure, are alive, and can carry out metabolism.

Dead cells: have a cellular structure, are inanimate, and cannot be metabolized.

Cell product: It has no cell structure but is vital.

Living cells are cells that can survive and function normally. Dead cells are cells that are unable to carry out activities, and cell products are substances secreted by cells during activity.
