The stages of mitosis can be seen by preparing a root tip squash.
The list below gives some of the steps involved in preparing a root tip squash.
The steps are not listed in the correct order.
1. heat the root tip in acid
2. warm gently to intensify the stain
3. press down gently on the cells
4. cover with a glass coverslip
5. add the stain to the root tip
6. tease the cells apart
Put a crossin the box next to the letter that shows the correct order for
these steps.
A 1, 5, 6, 4, 3, 2
B 1, 6, 3, 4, 5, 2
C 5, 2, 6, 1, 4, 3
D 6, 1, 5, 4, 3, 2
The only correct answer is A – 1, 5, 6, 4, 3, 2
B is incorrect because the coverslip has to be put on before the cells are squashed
C is incorrect because the cells cannot be teased apart before adding acid
D is incorrect because the cells cannot be teased apart before adding acid
