Parts of a Leaf
The flat green portion of a leaf
What is the blade?
Since plants can make their own food by photosynthesis, they are considered this type of organism.
What is an autotroph?
This process is how water vapor is lost from leaves
What is transpiration?
Leaves with one blade on every petiole
What are simple leaves?
The primary component of cell walls
What is cellulose?
This structure attaches the blade to the stem
What is the petiole?
Produced in the light reactions
What is ATP and NADPH?
Water inside cells produces this type of pressure
What is turgor pressure?
Identify this leaf arrangement.
What is alternate?
This vascular tissue conducts water and minerals upward
What is xylem?
This is the large central vein of the leaf
What is the midrib?
Photosynthesis occurs in the chloroplasts in this portion of the leaf
What is the mesophyll?
These cells control the movement of water and air through the stomata
What are guard cells?
This refers to having more than one blade on every petiole
What are compound leaves?
A storage area inside plant cells
What are vacuoles?
This structural tissue covers and protects a leaf's surfaces
What is epidermis?
This sugar is produced in the dark reactions
What is glucose?
Except in the fall, this green pigment will mask other pigments in the leaves.
What is Chlorophyll?
In this arrangement, two leaves grow from each node
What is opposite?
This plant tissue allows growth and repair
What is meristematic tissue?
These tiny openings in leaves are for water and air movement
What are stomata?
This is the single most important factor affecting photosynthesis
What is the intensity of light striking the leaf?
This separates the petiole and the stem so leaves fall
What is the abscission layer?
Identify this leaf venation
What is pinnate venation?
Cork and parenchyma are examples of this plant tissue
What is structural tissue?
