LEAF STRUCTURES
Target: I will be able to identify the cellular organelle and
plant structures involves in photosynthesis and define
transpiration.
Epidermis: Outer layer of tissues.
Pg. 47
Cuticle: Waxy, protective outer layer of epidermis that
prevents water loss on leaves, green stems, and fruits.
Palisade Mesophyll: loosely packed layer of
parenchyma tissues filled with chloroplasts.
Chloroplast: Where photosynthesis takes place in
plants and algae.
Chloroplasts contain the green pigment
chlorophyll.
Chlorophyll absorbs sunlight energy to start the
process of photosynthesis.
Vascular Bundle: xylem (moves water) and phloem
(moves food) tissues.
Leaf veins.
Spongy Mesophyll: layer of tissue, loosely
arranged to move oxygen, carbon dioxide, and
water.
Stomata: openings in leaves and some stems to
allow for the exchange of gases. Usually found on
the bottom of leaves.
Guard Cells: specialized kidney shaped cells that
open and close the stomata.
Transpiration: Loss of water through leaves.

Choose a clock question and complete what it is asking. If you choose
#11 (summary in 40 words, make sure it is the best; most thorough
summary possible).
