LEAF IT BE
These are a plant's primary organs for producing energy through photosynthesis and exchanging gases with the environment.
What are leaves?
Monocots have this type of venation - all the veins run parallel to each other.
What is parallel venation?
The two main parts of stems.
What are nodes and internodes?
Woody stems have their epidermis replaced by a meristematic layer called this which produces cells to protect and support the stem.
What is cork cambium?
These are the primary organs for anchoring a plant and normally grow from the stem.
What are roots?
If a plant retains its leaves throughout the year it is called this.
What is evergreen?
Dicots have this type of venation - the veins branch out and form a network of smaller veins.
What is netted venation?
Tiny structures of the nodes that will develop into branches. They are also your friends.
What are buds?
The main function of this in a stem is to allow water to flow between inner and outer layers of tissue and to exchange air with the environment through tiny pores in the surface of a woody stem.
What is the cortex?
This root system consists of one main root and lots of small roots branching from it.
What is a taproot system?
The broad part of a leaf.
What is a blade?
A leaf divided into two of more leaflets connected in one central location is this leaf type. Lucky you!
What is palmate?
Even though stems vary greatly, they can typically be divided into these two groups.
What are herbaceous and woody?
This thin layer of meristematic tissue in a woody stem produces a plant's xylem and phloem.
What is the vascular cambium?
This root system is many small roots that come straight from the stem and not a taproot.
What is a fibrous root system?
This tiny stalk attaches the blade to the stem of the plant.
What is the petiole?
These cells are modified epidermal cells that open and close a stoma.
What are guard cells?
Stems get longer through this type of growth.
What is primary?
These give us a good estimate of the age of a tree.
What are annual rings?
The root tip is covered by this, which is made of dead cells for protecting the delicate, fast-growing tissue.
What is a root cap?
This tiny leaf-like structure at the base of the petiole can protect a newly forming leaf.
What are stipules?
Also known as veins, these have tubes of xylem and phloem bundled together.
What are vascular bundles?
Stems get thicker through this type of growth.
What is secondary?
One __________________ ring and one __________________ ring make up one annual ring.
What are springwood and summerwood?
This meristematic tissue is used to form secondary roots that branch off the main root.
What is the pericycle?
