Do the bottom diagram Find all th calculations Micrograph width is 0.2mm at 400x Draw a micrograph diagram and calculations
Zea mays (corn, a monocot) leaf cross section,
100X.
В
A = spongy mesophyll; B = upper epidermis; C
= upper cuticle; D = xylem; E = vein; F =
phloem; G = lower cuticle; H = stoma, I =
guard cell, J = lower epidermis
Function:
The spongy mesophyll has air spaces for gas
exchange and produces carbohydrates by
photosynthesis. The upper and lower cuticle
protect the leaf from water, sealing water inside
and preventing excess rainwater from entering.
The upper and lower epidermis produce the
cuticle and protect the leaf from herbivores and
parasites. The xylem transports water into the
leaf while the phloem begins the sugar
transport down to the roots. The guard cells
open and close the stoma, which is the small air
space between them.
E-
Tissue Breakdown:
Epidermal tissue: epidermis.
Ground tissue: spongy mesophyll.
Vascular tissue: xylem and phloem.
Meristem tissue: none (leaves do not grow new
leaves).
F
C
At 40X, micrograph width = 2 mm; at 100X,
micrograph width = 0.8 mm; at 400X,
micrograph width = 0.2 mm; at 1000X,
micrograph width = 0.08 mm.
