waxy cuticle
|
water proof coating
translucent conserve h20 protect from sun damamge |
|
|
upper epidermis
|
protection
|
|
|
palisade layer
|
main phtosynethetic area
1-2 cells thick contains chloroplasts |
|
|
how palisade layer maximizes photosynthesis
|
that rotate through cytoplasmic streaming
elongated boxes w. vacuole filled with sugar solution that reflect/refract sunlight situated at top of leaf |
|
|
xylem
|
carries h2o and dissolved minerals
one direction from roots up to leaves |
|
|
phloem
|
narrow tubes to carry products of photosynthesis
|
|
|
spongy mesophyll
|
large cells with large vacuoles
lots of air spaces for gas exchange |
|
|
guard cells
|
surround the stomate
chloroplasts produce sugar fill with water during the day opens w/ osmotic pressure |
|
|
stomate
|
site of co2/o2 diffusion
|
|
|
transpiration
|
evaporation of water fro the surface of a leaf via stomates
1. water from xylem diffuses into spongy mesophyll 2. simple diffusion of water of out the leaf via stomates evaporation of water from the leaf pulls up water from the roots thru xylem |
|
|
cohesion
|
water molecules sticking together (hydrogen bonds0
|
|
|
adhesion
|
water molecules attracted to xylem
|
|
|
amount of water loss due to transpiration
|
abundance of water
time stomates are open environmen. conditions humidity, temp, wind |
