I did. I've read that cell is the basic unit of life, and that cells arise from existing cells. Cell theory also states that all living things are composed of one or more cells.
Hey Daniel, did you have an advance reading on the Postulates of Cell Theory?
Hey Chris! Why are you sleeping in my class?!
How about you? Have you read anything about Postulates of Cell Theory?
Yeah, I've learned some scientists that contributed to creating the theory. First is Antonie van Leeuwenhoek, also known as Father of Microbiology. He was the first person to examine many cells, including red blood cells. In addition to that, he was also the first person to see the nucleus of these blood cells.
Oh, I see. Do you know about the book Microphagia?
Yeah he is. Hooke discovered cells when he is observing cork through his mircroscope. What he saw was tiny boxlike cavities, which he later illustrated and called it cells.
Isn't it Robert Hooke that published that book?
Oh! It's already time for Biology!
Get up and answer this question! Who is the Father of Microbiology?
You don't know? Who will help him?
I'm sorry ma'am, I don't know.
It is Antonie van Leeuwenhoek. He was also the first person to examine a red blood cell.
That is Antonie van Leeuwenhoek. Good thing I did an advance reading.
