Question

9. Give a reason why the following steps are followed when preparing cross-sections of a leaf for examination under a microscope. i) Cutting thin sections Ii) placing the sections in water​

Answer 1

Step-by-step explanation:

i)A specimen being viewed under a microscope should be thin so that light can pass, Otherwise the light cannot get through the specimen. ... If they were not thin enough for light to pass through them, the subcellular structures would not be visible under a microscope.

ii

The thin layers of material placed on slides can dry up rapidly

Adding a drop of water to the specimen (beneath the coverslip) can prevent the cells from being damaged by dehydration
