Plants: finally!!!!!!

Chapter 35: Plant Anatomy -emphasis on Angiosperms Germination: growth from a seed - differs between monocots and dicots -2 types of growth: (1)primary (2)secondary ml

Roots: Tap Root

Adventitious Roots

Root Hairs

Monocots

Dicots (Eudicots)

And finally,my favorite type of plant...

All plants are made of 3 basic tissues: (1)Protoderm: the outside

Cuticle: Epidermis:

Stomata:

(2) Ground Meristem: the inside -3 types Parenchyma: working cells -photosynthesis & storage -ex: green cells in center of leaf, potato cells

Collenchyma: support (thick walls) -rib of leaf, bark of tree

Sclerenchyma: heavier structure -can be covered with lignin or minerals -ex: cherry pit, pistachio nut shells

(3)Procambium: vascular tissue -2 types: xylem and phloem Xylem: tracheids and vessel elements

Phloem: sieve tubes and companion cells
