Leaves Plant Jigsaw by Philip, Julia, Jessica, Mitti, and Chris
The Function of Leaves Leaves collect energy in the form of sunlight and provide it to the rest of the plant. This energy is necessary in the survival of the plant. They also are used to store food, water, and minerals as well.
Where are leaves located? Although there are many different plants with different types of leaves, one thing is the same for all of them: Leaves are located on the outside of the plant (either on top or to the http://pichost.me/1472464/ sides) so that they can collect sunlight.
Organization of Leaves on the Plant Plant leaves are organized/oriented throughout the plant so that they do not block the sun from one-another as well as having the wide sides facing upwards to collect more sunlight. All in all, leaves are the most http://animal-world. com/encyclo/fresh/plants/StemPlants/images/F exposed part of the plant in order ountainPlant_OphiopogonJaponicusWFPS_C1 094.jpg to retrieve the most sunlight.
Microscopic Structure of Leaves -Outer protective layer of cells are tightly comprised in the epidermis -Small group of collenchyma cells exist beneath epidermis and have stronger cell walls -The leaf tissue between the epidermis is called the mesophyll, containing the vascular tissues which are composed of veins and leaf traces -Cells within the vascular tissue consist of the xylem and phloem cells -2 sections of mesophyll: spongy and palisade parenchyma

How the Microscopic Structure Works -Cells on epidermis secrete a waxy layer called the cuticles, which helps the leaves retain water -The collenchyma cells provide additional support -The guard cells beside the stromata modify their size in order to reduce water loss and regulate gas exchange -The vascular tissues transport water and minerals to diff. parts of the leaf -Parenchyma sections contain the chloroplasts for photosynthesis, these cells have thin, flexible walls
