Is it true that all living cells are made from other LIVING cells?

Question

My science teacher gave us notes and it put this in them and I dont know if it is true.

Answer 1

Cell reproduce by means of mitosis and meiosis... your teacher should have said cells are made BY living cells, but she's not wrong.

Answer 2

yes. there is no known instance of a living cell coming from anything other than a living cell in modern times. The idea is that ONCE a long time ago organic material were happened to be arranged into a reproducible form. Complexities grew and all modern cells are thought to be offspring of the first rare event...

Answer 3

Yes, there is no spontaneous generation of life. At one time it was thought life could arise from nonliving mater, that flies arose from manure not fly eggs in the manure. This was disproved in the 17th century by showing that if flies where prevented from laying eggs no maggots ever appeared on meat. This is when the theory of everything arising from an egg was postulated. Louis Pasteur did the experiment of boiling broth then keeping it isolated to show that microbes are destroyed and do not return, hence pasteurization.

Spontaneous generation is called abiogenesis or birth without life.
Then you say where did life arise. At one time life did arise with the advent of self-replicating macromolecules but not now. There is no evidence of continuing spontaneous generation.

Answer 4

a cell is a living organism but a cell is the smallest possible "building block" of life, cells are made up of elements. for example humans are mainly carbon hydrogen oxygen and nitrogen.

Answer 5

Yes, it's part of the cell theory

Cells come from pre-existing cells.

Answer 6

Cells make cells?

But then by her logic cells would make up THOSE cells

Then cells would make up those and so on and so on for ever and ever

So wow that is deep stuff. Seriously deep stuff.

Answer 7

yes.
