If you are referring to trees then the answer in general is vascular cells. In the gymnosperms (softwoods like conifers) water transport is done mainly by tracheids. In the angiosperms (hardwoods like Oak, Maple, Poplar, etc.) the transport is done by a combination of vessels, axial parenchyma, tracheids and somewhat by fibers. The interesting fact is that the water transport is only done in the outer few rings of the sapwood. The heartwood cells are dead and serve as mechanical support
The structure that brings water from the roots to the leaf is the vascular tissue called the xylem. The process is called transpiration, and as water leaves the leaf by evaporation, the water molecules are pulled up the xylem by the polar nature of water and a meniscus process in the mesophyll cells that is too complex for this level of answer.

a leaf does not obtain water, it obtains energy from light. Roots obtain water
These are the xylem cells that transport water into the plant from the roots. They are also dead.
A Root cell doesn't have any Chloroplasts on them where as leaf cells do. Leaf cells need sunlight which is absorbed into the cells of the leaf: this job is done by the chloroplasts present in the cells, but when the roots are present under the ground, the cells do not need sunlight. hope u got Ur answer.
Water from the xylem (vessel carrying water and minerals from roots to leaves) through osmosis going into the leaf cells (mesophyll cells) then diffused into the air space between these cells. When the water potential inside the leaf has a higher water potential then its soundings the water diffuses out of the stoma as water vapour. Thats the simple version!
The leaf doesn't have roots. It's the plant that has roots.
roots
the roots make the water flow up from the ground through the xylem.
The plant obtains water (H2O) from the soil, the water molecules then go into the root cells, through the vascular tissue in the stem, and to the leaves.
Because water makes plants do good growing.
By photosynthesizing and taking in nutrients and mineral salts from the roots
a leaf does not obtain water, it obtains energy from light. Roots obtain water
These are the xylem cells that transport water into the plant from the roots. They are also dead.
water
plants can absorb water through tiny pores in their roots. i dont know what the pores are called though. they also gain water by their leaves through holes which are called stroma, this is a gap in the leaf, and is surrounded by Guard Cells.
The chloroplasts in the leaves absorb the light directly from the sun. The carbon dioxide goes into the leaves through the stomata (tiny holes on the bottom of a leaf) and is diffused through the rest of the cells. The water is absorbed by the roots then carried by the xylem up to the leaf and the cells in the leaf.
The Part Of The Sunflower Which Absorbs Water And Nutrients Is The Roots Of The Sunflower
