please help me ​

Answer 1

Answer:

In the microscopic analysis of animal and plant tissues, thin sections of tissue are required to achieve a slice with only one or a few layers of cells. ... The sections are then stained with differential stains to help distinguish between cell walls made of cellulose and lignin, and thus identify phloem and xylem.

This experiment is done to check the movement of water in stem in which ink is mixed with water and the stem is left in the mixture and after an hour we observe the stem and it shows that the ink is present inside the stem shows that the stem conducted the water and the ink, as well as the colored ink patches, are observing it proves that  the xylem and its elements help stem to conduct the water.

So the correct option is 'The conduction of water and ink by the stem'
