The photo below is for your reference. You may simply consider that chromatin is a structure/state when proteins and DNA are loosely packed. And chromosome is a structure/state that proteins and DNA are tightly coiled and packed. During cell division (meiosis or mitosis) loosely packed chromatins will pack itself tightly to become chromosomes. That's why during prophase, we have an observation: chromosomes become visible.

@@BiologyMan Thank you for your explanation. I understood now. I found you don't have a video about photosynthesis. Can you talk about this topic especially light reaction and Calvin cycle? I love to learn more. ^^

Juno同學，我同語音答你。請click入以上的語音留言。
miss I can’t listen to this recording, it seems that it has no sound or out of date.
Miss,姊妹染色單體同非姊妹染色單體有咩分別？🙏
姊妹染色單體係一條染色體入面嗰兩條。
非姊妹染色單體係不同染色體嘅染色單體。
miss man, can you explain what the difference between chromosome and chromatin for me?
