Roots Just as important as stems and leaves…. Major Functions:1. Serve as an anchor 2. Conduct nutrients and water 3. Store food (ex. sweet potatoes, carrots, radish, turnip, beet)
Root Development Primary root develops from the embryo1. If primary root becomes the main root=Taproot System
Root Development 2. If primary root stops growing early on and new roots grow from the stem, it is a Fibrous Root System
Fibrous vs. Taproot
Root Hairs Grow from epidermal cells of rootsOnly occur in first ¼ of root tip Only live about 10 days Absorb water and nutrients from soil particles
Function of Root Hairs
Food Storage Roots Most roots store some foodSome are enlarged to store starch and other carbohydrates Examples: sweet potato, carrot, beet, radish
Water Storing Roots Produced by plants in arid regionsCan be quite large (159 lbs.!) Examples: Manroot
Manroot Grows close to ground: perennial vine Roots can be several meters long and over 100lbs.
Pneumatophores Extend above the surface of water for plants that grow in swampy areas Helps roots exchange gases Example: Mangrove
Aerial Roots Roots that occur above the surface of the soilExamples: prop roots in corn (support in high wind)
Aerial Roots ContinuedAdventitious roots in ivy for climbing
Contractile Roots Help to pull the plant deeper into the soilOccurs from year to year Examples: Lily, Dandelion
Parasitic Roots Peg-like projections penetrate host’s stemUsually in plants that do not contain chlorophyll (can’t make food) Examples: pinedrops, dodder (one organisms benefits, one is harmed)
Dodder: NO Chlorophyll—Not green!
Buttress Roots Huge roots near base of trunkUsually in trees that grow in shallow soil Rainforest environments Example: many tropical trees
Dicot Root Tip

Students will be able to know the 3 different types of roots systems and identify them by going outside.

Roots, Stems, and Leaves. Roots Types of roots –Taproot: primary root that grows longer and thicker than the secondary roots (grows deeper) ex. carrots.
Roots and Stems. Functions of Roots Anchor the plant Absorb water and nutrients from the soil and transports them to the stems and leaves Store.
The Root System.
Plant Structures and Functions. Structures and Functions Structure- means a part. Examples: roots, stems, and leaves. Function- means a job.

Roots Main function: –Absorb water & nutrients Transport them to the above ground plant –Anchor the plant in the ground –Some store energy as carbohydrates.

PLANT STRUCTURE AND FUNCTION
Plants Why do Plants Need Roots & Stems?. How Roots Help Plants… The root system of a plant is often found below the ground where you can’t see it.
ROOTS!! The place where the journey begins. There are 4 jobs that roots do: 1.Anchor – The tree failed before the roots. – Why do most trees fall when.
21.3 Roots and Stems KEY CONCEPT Roots and stems form the support system of vascular plants.
ROOT SYSTEMS. ROOT ORGANIZATION Roots systems are usually either: Tap root (dicots) or Fibrous root (monocots) some plants may have both; e.g. clover.
