Performance Objectives
On a demonstration evaluation, students will be able to identify and describe the various parts of the turfgrass plants and their use in the identification of major turfgrass species with 80% accuracy Identify and describe the major parts of the turfgrass
plantDescribe the difference between tillering,
stoloniferus, and rhizomatous speciesRecognize the different leaf tips, leaf surfaces,
auricles, collars, ligules, and vernation and how they are used in the identification of major species.

The Importance of Turfgrass
How many people play sports or
enjoy watching sports?
Why would it be important to know which species of turfgrass is
present?

Taking Me Back to Yesterday
Key PointsMonocots- 1 Seed Leaf at Germination,
Scattered Vascular Bundles, and have primary growth only
Dicots- 2 Seed Leaves at Germination, Concentric Vascular Bundles, and has primary and secondary growth
Photosynthesis- The Process of Turning Carbon Dioxide and Water into Sugar and Oxygen
Respiration: The use of Energy from Stored Compounds.

Parts of the Turfgrass Plants
The Stem
The Leaves
The Roots
The Seed Head
![Page 6: The Grass Between My Toes: Wait! Is That Fescue? Mr. Dale Cruzan Turf Grass Establishment & Maintenance](https://reader035.vdocuments.net/reader035/viewer/2022062516/56649d9f5503460f94a8967d/html5/thumbnails/6.jpg)
The Stem
Primary Stem Provides support for the
turf plant Supplies water, sugars,
and minerals to the plant, transports sugars downward.
The Stolon: An Aboveground Stem. Often grows roots
Rhizome: A below ground stemt. Often grows roots

The Leaves
The leaf’s primary purpose is to collect sunlight and exchange gases.
The primary site of photosynthesis
Major Parts of the Leaf: Midrib Blade
![Page 8: The Grass Between My Toes: Wait! Is That Fescue? Mr. Dale Cruzan Turf Grass Establishment & Maintenance](https://reader035.vdocuments.net/reader035/viewer/2022062516/56649d9f5503460f94a8967d/html5/thumbnails/8.jpg)
The Roots
Store sugars, absorbs nutrients and water, and provides support for the plant.
Primary Roots- The Main Root
Lateral Root- Secondary Roots off the Primary
Root Hairs- Hair like roots that uptake water and nutrients

The Seed Head
Begins as a flower
When flowers are pollinated, it begins to form a seed head.
The purpose is to distribute the seeds and start new grass plants
Often undesirable in manicured turf
