Tracheophytes – Vascular plants “Roots and Shoots”
Above ground = shoots Under ground = roots
Three tissue types Dermal tissues Vascular tissues Ground tissues
Major organs (non-reproductive) Leaf Stem Root

Meristemic Tissue – only regions where cells divide repeatedly by mitosis (sites of growth)
Tissue Description Function
apical meristem at root and shoot tips primary growth – increases in LENGTH
lateral meristem cylinders of tissue within roots and stems
secondary growth – increases in diameter
![Page 7: Monocots and Eudicots (Dicots) …the most abundant vascular plants.](https://reader036.fdocuments.in/reader036/viewer/2022062309/5697bf751a28abf838c80704/html5/thumbnails/7.jpg)
Dermal – a plants skin (protective)
Tissue Description Function
Epidermis -outermost cell layer in primary growth regions
Produces waxy cuticle – prevents water loss and infection, restricts gas exchange
Periderm -outside layer at sites experiencing secondary growth-replaces epidermis-often multiple cell layers
Waterproofs roots and stems, protects inner tissues from structural damage

Ground – all the internal nonvascular regions
Tissue Description Function
Parenchyma Spherical, thin-celled walls with large vacuoles
-Storage of nutrients, carbs (sugars and starches) and water-heals wounds, regenerates plant parts
Collenchyma Long cells with thickened cell walls -strength-supports primary growth regions-flexibility to withstand wind
Sclerenchyma -very thick secondary cell wall of cellulose and lignin-long cells
-Strength and rigidity

Vascular – a plant’s circulatory system (transport)
Tissue Description Function
Xylem -tracheids long, tapered, thick-walled cells with overlapping ends and pits (unthickened areas) on cell walls-vessel elements – short, large diameter thick walled cells with open ends; stacked like barrels to make vessels
Transports water and dissolved minerals, usually upward from roots to leaves

Vascular – a plant’s circulatory system (transport)
Tissue Description Function
Phloem Sieve tube elements – long thin cells with tiny holes at the sloping ends (a sieve), and pits along side alls; no nucleus, ribosomes, Golgi, vacuoles, stacked to form sieve tubes
-transports food (sugars etc) from leaves to the plant bodyCompanion cells: direct sieve tubes
