Vocabulary
Clusters of tissue that are responsible for continuing growth through a plant's lifetime.
Meristems
Plants consist of three main tissue systems. What are they?
Dermal, Vascular, and Ground
In general, stems have three important functions. They are:
To produce leaves, branches and flowers
To hold leaves up to the sunlight
To transport substances between roots and leaves
The leaves of the plant are the main organ of what?
Photosynthesis
Of the three forces that move water through a plant, which is the most forceful?
Transpiration
This type of root grows long and thick while the secondary roots remain small.
Taproot
The principal subsystems in vascular tissue are?
Xylem and Phloem
What are the major subsystems of the stem’s transport system.
Xylem and Phloem
Together, the cuticle and epidermal cells form this type of barrier that protects tissues and limits the loss of water through evaporation.
Waterproof
The combo of these three things are forceful enough to move water through even the tallest plant.
root pressure, capillary action, and transpiration
The area of plants where leaves are attached.
the Node
On the underside of leaves, this tissue contains guard cells which regulate water loss and gas exchange.
Dermal
In Dicot Stems, Vascular Bundles are arranged in this type of pattern:
Circular
The bulk of most leaves consists of specialized ground tissue called
Mesophyll
This type of pressure keeps a plant’s leaves and stems rigid.
a thin, flattened section of a leaf where sunlight is collected.
Blade
The cells between dermal and vascular tissues are:
Ground Tissues
This method of growth involves stems growing in width.
Secondary Growth
This layer of mesophyll is located under the epidermis and absorbs light that enters the leaf.
palisade mesophyll
Many plants pump sugars into their fruits. This movement takes place in the what?
Phloem
A force that describe the attraction of unlike molecules
Adhesion
Meristematic tissue is the only plant tissue that provides new cells by:
Mitosis
As woody stems grow thicker, the older xylem near the center no longer conducts water and instead becomes known as:
Heartwood
Each stoma consists of guard cells that control the opening and closing of the stomata. How many are there?
2
This is where sugars are used or stored.
The Sink
