Plant Adaptations!
Changes over time…

Common Adaptations in Plants
• 1. CELLULOSE– Most cell walls have cellulose– Cellulose – makes the cell wall thick and offers
protection and support to the plant– What makes the plants we eat “crunchy”

ROOTS
• Very commonly found in plants
• Part of the plants that enter into the dirt
• Take in water and nutrients for the plant

Roots, roots, and more roots

Roots Galore!!

Types of Roots

Stems
• Provide structural support so plants can grow upright
• Have tissues for food and water transport– The more complicated these tissues are the bigger
and more complicated the plant• May also serve as a storage space for sugars
and nutrients

Stems
The secret to the flow of water and nutrients of plants lies here in the stems!!!!

Leaves•Broad Flat Structures on a plant

LeavesTraps the light so that it can be used for photosynthesis
Come in many different shapes and sizes!!

Waxy Cuticle
• Water proof coating found on the stems and leaves of some plants
• May also be found on the fruits of some plants
![Page 15: Plant Adaptations!](https://reader036.fdocuments.us/reader036/viewer/2022062315/56816620550346895dd9742f/html5/thumbnails/15.jpg)
Waxy cuticle (cont)
• The job of the cuticle is to prevent water from leaving the plant and going into the atmosphere.

Two Groups
• These adaptations help us determine how to classify the plants
![Page 17: Plant Adaptations!](https://reader036.fdocuments.us/reader036/viewer/2022062315/56816620550346895dd9742f/html5/thumbnails/17.jpg)
Vascular vs. Non-Vascular
• These two groups vascular and non-vascular plants have distinct differences.
• You are probably most familiar with the vascular plants.
![Page 18: Plant Adaptations!](https://reader036.fdocuments.us/reader036/viewer/2022062315/56816620550346895dd9742f/html5/thumbnails/18.jpg)
Non-Vascular Plants
• Less common of the two groups
• Typically found in moist or watery environments
• Smaller plants• Less structure• Get Water and nutrients
through diffusions and osmosis
• Ex: Mosses and LiverwortsCushion Moss

Liverworts
![Page 20: Plant Adaptations!](https://reader036.fdocuments.us/reader036/viewer/2022062315/56816620550346895dd9742f/html5/thumbnails/20.jpg)
Sphagnum Moss – Use to be used as a bandage to soak on blood and help heal wounds!!!
![Page 21: Plant Adaptations!](https://reader036.fdocuments.us/reader036/viewer/2022062315/56816620550346895dd9742f/html5/thumbnails/21.jpg)
Vascular Plants
• Have “Vascular Tissue”• Tube like structures for passing
water and nutrients up to the leaves
Examples of Vascular Tissue:– Xylem and Phloem– Bark – Stems
These little holes and pores is what the water and nutrients travel through to the leaves
![Page 22: Plant Adaptations!](https://reader036.fdocuments.us/reader036/viewer/2022062315/56816620550346895dd9742f/html5/thumbnails/22.jpg)
Vascular Plants (cont)
Most of the Produce Seeds• Ex:
– Trees– Flowering Plants– Ferns– Horsetails– Fruit Producing Plants

Vascular Plants
Typically they are taller plants
