where do all cells come from and how do they reproduce? explain in an easy way please I have trouble understanding

Cells get produced by preexisting cells which is called cell production or division.

Explanation:

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
