SNC 2D1
Ms Parmar
plants convert ________
E. into chemical E., and
store it on the bonds of
sugar
plants & animals convert
stored ______________
into E. (release E. from
food)
1. Write the balanced chemical eqn for photosynthesis (“PS”). Where does PS occur in a plant? Be specific (cell
type, organ type).
6CO2 + 6H20 + Energy -----> C6H12O6 + 6O2
2. Write the balanced chemical eqn for respiration. Where does it occur in a plant?
C6H12O6 + 6O2 -------> 6CO2 + 6H2O + Energy
3. Label these parts on the following diagrams:
A. stem
D. blade
G. branch root
J. leaflet
B. meristem
C. petiole
E. leaf
F. primary root
H. hypocotyl
I. lateral bud
(hint: see diagram, next page)
Does the diagram above
model ps or respiration?

F. thykaloid
I. anther
J. upper epidermis
M. stigma
N. lower epidermis
Q. style
R. receptacle
U. ovary
V. palisade mesophyll
X. spongy mesophyll Y. guard cell

G. filament
H. carpel
K. leaflet
L. ovule
O. stamen
P. sepal
S. peduncle
T. petal
W. bundle sheath cells
I. LEAF LAYER
IV. LEAF TISSUE: ON THE
LOWER EPIDERMIS
II. FLOWER
III. CHLOROPLAST
5. Is this xylem
tissue or phloem
tissue? What 2
clues give away the
answer?
reasons.
6. Find the terminal bud, above. It releases
the hormone, __________________, which
prevents the _________________ _______
from growing too far outward.
7.
Add sketches/notes. THE BIG QUESTION: HOW DO SPECIALIZATION & STRUCTURE HELP PLANTS FUNCTION?
PLANT ORGANS
- ROOT
- meristem
- taproot
- primary + branch roots
-
STEM
lateral & terminal buds
more meristem!
xylem + phloem tissue
- LEAF
- petiole, vein, blade
- chloroplasts in mesophyll cells
- stoma & guard cells
PLANT TISSUE
FUNCTION + SKETCHES TO SHOW STRUCTURE
- anchors the plant
- absorbs, stores nutrients
- provides support
- transports _____
- REMEMBER: meristematic tissue is made
of: specialized / unspecialized (circle one answer)
- main organ for _________________
to occur
FUNCTION + SKETCHES TO SHOW STRUCTURE
- DERMAL
- e.g., epidermis
- e.g., cuticle
- e.g., guard cells surrounding
stoma (a hole) in the epidermal
layer
- outer protective covering
- keeps _____________ in the plant
- controls passage of ______and _______ gas in/out of plant
- VASCULAR
- e.g., xylem tissue
- e.g., phloem tissue
- plant plumbing
- xylem transport
_______________ and
__________________
while phloem transport

- How do their structures
relate to their functions?
- GROUND
- palisade mesophyll
- spongy mesophyll
- and this type of tissue does…everything that vascular and dermal do NOT do!
- stores starches in the form of _______________ and vegetables
- includes all areas where photosynthesis and __________________________
occur
- provides ________________ to the plant
