You have been given a plant sample and asked to identify a specific tissue. Upon investigation, you find the cells are all long in length and some of them have small pores. They all contain fluid. You test the fluid using various biochemical tests and discover the fluid contains an abundance of disaccharides. What type of tissue are you looking at?

The tissue is called phloem.

Explanation:

Phloem is a living tissue that is present in vascular plants.During the process of photosynthesis, it helps to transport sucrose (Disaccharide) and other minerals to the different parts of their body.Phloem is composed of sieve elements, parenchyma, albuminous cells, supporting cells etc.Phloem contain small pore that contain fluid which is transferred by supporting cells ( the primary function  performed by this cell)Sieve elements also helps to transport phloem sap fluid throughout the plant body.Sieve element contain vacuole and other organelle like ribosome, endoplasmic reticulum etc.
