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
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
Leaves Traps 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
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
Vascular vs. Non-Vascular • These two groups vascular and non-vascular plants have distinct differences. • You are probably most familiar with the vascular plants.
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 Liverworts Cushion Moss
Sphagnum Moss – Use to be used as a bandage to soak on blood and help heal wounds!!!
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
Vascular Plants (cont) Most of the Produce Seeds • Ex: • Trees • Flowering Plants • Ferns • Horsetails • Fruit Producing Plants
Vascular Plants Typically they are taller plants
