Yum, Nutrients!

Today is April 1st, and my babies are growing strong. I water them when their soil is dry and I give them sunlight daily. Roots are necessary for the transfer of nutrients and water. 
The roots of the corn have grown so long they have wrapped around the bottom of their abode! It is more difficult to see the roots of the carrots though. I have decided to name my babies now that they are flourishing. My carrot plant's name is Kaylinn. The three corn plants are triplets and are named: Tod, Troy, and Tyson. For the four plants to gain nutrients, they must utilize their roots and various other structures. Vascular tissue, xylem, stomata, guard cells, transpiration, turgor pressure, soil, and the the casparian strip. The structures' functions are as follows:
Vascular Tissue: This is plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body.
Xylem: Vascular plant tissue that consists mainly of tubular dead cells that conduct most of the water and minerals upward from the roots to the rest of the plant.
Stomata: Tiny openings in the epidermis of the plant. Gases and water vapor pass through these tiny openings. These structures permit the absorption of carbon dioxide and the realease of oxygen gas. 
Guard Cells: Two cells that flank the stomatal pore and regulate the opening and closing of the pore.
Transpiration: The process of water flowing from the roots through the stem of the plant and out of the plant, evaporating.
Turgor Pressure: The force directed against a plant cell wall after the influx of water and the swelling of the cell due to osmosis. 
Soil's Contribution to Plant Growth: Soil contributes by nutrients, the pH balance, water, and anchoring. The pH balance germinates the seed. The soil absorbs and provides nutrients and water. The soil also anchors the plant so it can grow and develop successfully. 
Casparian Strip: A water impermeable ring of wax in the endodermal cells of plants that blocks the passive flow of water and solutes into the stele by the way of cell walls. 

For food delivery, translocation and phloem are necessary. 
Translocation: The conduction of soluble food material from one part of a plant to another.
Phloem: Vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant.
