Vascular System (veins): Xylem and Phloem
• There are two tubes found inside most plants: xylem and phloem.
Xylem : transports nutrients and water from the roots of the plant to every area of the plant.
Phloem : transports nutrients (mostly sugars that are made during photosynthesis from the leaves to the rest of the plant

Stomata
Is a small opening on the bottom of a leafthat gases pass in and out of (CO2, O2, H2O).

Chloroplasts
This is where photosynthesis takes place.Chloroplasts produce oxygen and sugar.

Upper Epidermis
Is the top layer of a leaf.The cells in the epidermishave a waterproof coatingthat prevents water loss.

PhotosynthesisIs a process performed by chloroplasts in a leaf in which sugar (glucose) and oxygen are produced. This process requires sunlight, carbon dioxide, and water.

Is the green pigment of plants that traps the energy of sunlight from photosynthesis.
