Try to find yourself. Start with google. I'm sure you will find the answers.

Mytosis is the division of diploid cells; the diploid number is preserved in daughter cell; infact every chromosome duplicates and generates another one chromatide; one of it in the anafase passes to daughter cell.
Meiosis instead involves sexual cells; they are aploid, but a fertilized eeg is diploid: for it the cell division are two; in the first one every chromosome separates from another and the cell become aploid again; the second division is a normal mitosis where chromatides of every chromosome separates.

yes that's right. By mitosis, from one cell "born" 2 daughter cells with same chromosomes number (diploid for human), while by meiosis, after 2 divisions (the last is mitosis-like), from one cell "born" 4 cells with half chromosomes number (for human only gametes have meiosis and these cells called aploid).
