CBSE Class 9 Answered
According to your video (Introduction to Cell, Part 1), Anton Von Leeuwenhoek observed living cells for the first time in 1964. But in the 9th NCERT Science book (Page no. 58, Yellow box), the year is 1674. Wikipedia also states that Leeuwenhoek lived from October 24, 1632 to August 26, 1723. This means that he couldn't observe the living cells in 1964. Which is the correct year?
