External Structure
Large, central vein
midrib
This type of vascular tissue carries sap upward from the roots to the leaves
xylem
The vascular tissue that carries sugar from a plant's leaves to the roots and stem
phloem
The pressure produced by water within cells
turgor pressure
Storage compartment within a cell
vacuole
Stalk that attaches the leaf to the stem
petiole
Protects and covers the leaf
epidermis
Main type of plant tissue that forms most of the body of a plant
structural tissue
Plants whose special leaves trap and digest insects
insectivorous plants
This type of venation is when a leaf has small veins extending outward from a single main vein
pinnate
Leaves, stems, and flowers are part of this system
shoot system
Opening in the leaf
stoma
In photosynthesis, a plant uses light energy, water and carbon dioxide to produce these
glucose oxygen
This type of special leaf holds a vine upright by coiling around a support structure
tendril
Middle layer of the leaf, where most photosynthesis occurs
mesophyll
A leaf having more than one blade on the leafstalk (single petiole)
compound leaf
This type of cell controls the flow of air (and water) into and out of the leaf
guard cells
These compounds are produced by the light reactions of photosynthesis
NADPH ATP
The process by which water vapor is lost from the leaves of plants
transpiration
This carbohydrate strengthens plant cell walls
cellulose
A leaf that lacks a petiole
sessile
Cork and parenchyma are this type of tissue
structural tissue
Plants are considered this because they conduct photosynthesis (produce their own food)
autotrophs
An abscission layer is involved in this
loss of leaves
This type of plant tissue is responsible for the growth and repair of plant parts
meristematic tissue
